Do TPI bikes foul plugs? Sensor problems? The TPI air screw mod? How does TPI KTM or Husqvarna compare to the carb models? The TPI bikes typically have a softer bottom end power delivery, but similar top end. The main reason is a softer ignition curve, but the location of the injectors also contributed due to a reduced opportunity for fuel/air to mix properly at low revs. So this is a TPI review. Some models have spluttered at low revs. But the carb models can have problems too. Since 2017 the jetting has caused spluttery power and poor fuel economy. We will talk about TPI sensor problems soon. The finicky Mikuni carb is extremely difficult to get running consistently. Both carby and TPI bikes respond very well to basic mods. And once set up correctly both have very similar power delivery. Do TPI bikes need rebuilds more often? We suggest top end rebuilds every 80 to 100 hours maximum for a 250 or 300. The TPIs are especially sensitive to top end wear as blow-by past the rings will begin to alter the crank pressure readings sent to the ECU. How reliable is a TPI bike? Generally they are reliable but there have been issues with some of the 17 ECU maps released by the factory. Some caused problems, others have been much better. We find the TPIs are reliable once a few basic mods are done. The most important mods? Incorrect TPI air screw setting. This is used to adjust the idle speed, but it has effects on midrange revs too. Remove the stock grub screw and fit a longer bolt that can be adjusted by hand while the engine is running. Incorrect settings result in a weak or hanging idle, spluttery power delivery, and poor throttle response. Use the latest extreme mapping from the factory, which uses more oil. And fit an idle bolt, which allows separate tuning of the air and idle settings on the throttle body. Lets look at specific issues. Has a lack of oil caused problems? On some TPI models, yes. Fouling spark plugs. A lack of oil can cause significant wear up the back wall of the cylinder, usually centered over the rear boost port. You can check by removing your exhaust and looking at the back wall of the cylinder for vertical black or grey marks. The 2018 and 2019 models used a reasonable amount of oil, although some used less than others. The oil tank did not have a screen in it so it was important to clean the tank and test the output of the oil pump. 2020 models had a screen fitted to the tank but unfortunately the mapping used less oil, causing a high number of failures on low hour bikes. The factory has now released new extreme maps. These bring the oil level back to roughly the same level as the 2019 bikes, Fouling plugs at startup. This emerged with 2020 and 2021 models. A simple solution was to pull out the cold start knob on the side of the throttle body when starting the bike cold, and let it idle for a few minutes before touching the throttle. A more permanent fix is to update the ECU with more appropriate fuel maps. The ECU reflash that we offer addresses this issue and virtually eliminates plug fouling. If you consistently foul plugs you can use the cheaper NGK BPR7ES or BPR8ES plugs. These still perform very well but at a fraction of the cost. Remember if your bike suddenly starts fouling plugs it might be a worn top end or a faulty crank pressure sensor. Spluttery power at lower revs. Some 2018 and 2019 KTM and Husqvarna TPI models had spluttering and unpredictable power delivery at part throttle and lower revs due to issues with the stock mapping. The only complete solution is to reflash the stock ECU with improved maps. But it pays to check other possible causes first: a faulty crankcase pressure sensor, an incorrect air screw setting, low fuel pressure, or a worn top end. Do I need to replace the oil pump regularly? Generally the oil pumps are very reliable unless they get dirt or grit inside them. As mentioned the 18 and 19 models had no oil screen and were susceptible. Faulty Crankcase Pressure Sensors (CCP).The ECU uses the data from these sensors to determine the fuel, ignition and oil needs of the engine. But it will usually be fine at higher revs. The easiest test is to swap the crankcase pressure sensor with the ambient pressure sensor as they are identical.

My riding buddy had a ‘21 seize in less than 10 minutes of total run time. KTM gave him a replacement which made it to 20 hours before seizing. KTM rebuilt it, but it took several months because there was a shortage of top end parts. They ended up getting spare parts from one of their race teams in US (we are in Canada). That shortage of parts, along with KTM’s hard enduro riders recently spotted riding bikes with a different injection system tells me all I need to know about buying a current TPI.
That must have been frustrating. We had that issue in Australia apparently... there was a shortage on top ends due to the number of bikes seizing and getting fixed under warranty. 😢
My 2022 got a remap runs amazing and uses a fair amount of oil compared to before. Rebuilt my bike at 180 hrs and the piston was in perfect condition, I’ve never fouled a plug either. Loving my set up!
I have a 2022 TE150 tpi that ive not been able to ride yet but next summer I will. I let it sit too long and now it wont start, turns over fine but wont start so need to figure that out. Where did you get you ECO flashed?
Jeeesus! Top end rebuild every 80-100 hours. I'm nudging 500 hours on my 2014 Beta 300 Race edition, and its still on its first replacement piston and rings!! Go the might 2 stroke carb!
did mine on 300 hours and old piston was still fine. could easily ride it more. 250 tpi 2019
I’d say that’s more on how you ride
500 hours! Is this an experiment just to see how far you can go? I figure you can do the bottom end at the same time in that case lol. All the mechanics I know are unofficially saying 200 hours should be fine if you aren't pushing a two stroke carb model hard. I should point out quite a few TPI owners have gone that far (or more) without problems, although chances are these will be 2018 and 2019 models which had mapping that used a reasonable amount of oil.
@@crosstrainingenduro I had over 300 Hr on my 08 xcw before a rebuild ,piston and rings were still within specs. Lost the plastic cage on the big end bearing after I drowned the bike in a pond. No other damage ,Optimal at 100:1 ,no racing.
@@jamesdenton3692you made 300h at a 100:1? You're officially introduced to my list of reason why 2 stroke are amazing
Priceless video Barry… great info 👏🏼👏🏼👏🏼
Glad it was helpful, Gordon. Lets hope the system works better in 2022 models.
Great info for owners of these bikes, Barry.
Also good to put into perspective the fact that no one brand is free from problems and they each have little niggles to work through.
Cheers mate. A lot of TPI models have treated their owners well but a significant percentage haven't. KTM seems to specialise in not quite getting things right then using their customers as guinea pigs lol.
@@crosstrainingenduro
Agreed
niggles?
Glad I snapped up the last 2018 carbed xcw at my local dealer…at a HUGE discount because nobody wanted them at the time! 😎👍 All the carb needed to get it running 100% was a $10 gasket and a JD jetting kit.
A friend of mine did the same, snapped up the last carb 250EXC. We tested it against a TPI 250 that was full remapped and had an aftermarket head... no comparison! The carb is just so much more responsive and far more grunt. The bikes are only comparable at high revs.
Great tips and all the advice still holds up. Watched this video a couple times since it came out.
Great to hear, Brian! I was just chatting with a mechanic who says he has a stream of TPIs coming into his workshop... all year models. It's becoming the majority of his work. 🤔 We can only hope they eventually iron out the bugs. My mate who bought a TM EN300 with TPI had to sell it back to the dealer as they couldn't fix the issues. Thankfully we still have carb models with other brands!
@@crosstrainingenduro my 2020 150tpi just got new piston, sx head and adjustment screw. It feels good as new 😌
Decided to swap to 2T. Owned a 350 exc-f and 1 month ago purchased a 2022 Te150i. Amazing great fun bike to ride. Still not used with the 2T smell nor the sound, however I feel I'm becoming a better rider with this one. I can lug it everywhere. Have already 25 hrs on it. I had issues with it in the beginning, had that sputter in low-mid revs that I couldn't figure out. Swapped the sensors, no change. Bought a tacho and noticed that the factory idle was way high - 1800 rpm, while the manual states 1400-1500. I've turned in the air bypass screw to have the idle as manual says and now it runs better. After an 1 hour ride, I even get now a slight oil leak on the exhaust. It still sputters ocasionally, but doesn't bother me as long as the bike performs well. I guess it's a mapping issue. I wouldn't invest another 900 on a remap and a head insert to be honest as long as I have fun with this bike. Also, in the beginning I was very frustrated because I didn't know how to properly warm up the bike. These bikes are very sensitive until they reach the proper operating temp. 150s run extremely cold. I've installed a fan, but it has never started 🙄
Greetings from Romania Barry!
Buna, Mircea! I'm glad you are enjoying the 150...
It's nice that these bikes have been around long enough to start having more reliable info, common issues and more importantly fixes
Fathers bike had a faulty crankcase pressure sensor and it was very difficult to diagnose almost 2 years ago but now its just common knowledge that those wear out
I guess it's why many don't buy the first year or two of a model with a big innovation, Spencer.
2020 KTM 300 XC-W 6 days.
Bought brand new, and traded in at 100 hours. I had ZERO issues with this bike. Performed basic maintenance as required, ran US 91 octane ethanol free, used Mgf's oil's., changed the stock plug at 50 hours with no reason to other than it is spec'ed maintenance wise. Top end was clean. The front and rear sprocket had plenty of life, and the wheels had no play in the bearings at all.
After 100 hours, minus some dings, scratches, some peeling graphics, the bike ran as good as the day I bought it. The only reason it went out the door was to make room for the 2022 model and a fresher machine. 4th 300 XC'W I have owned since 2009, and never had issues with any of them. Previous to my last 300, I owned and built a Yamaha YZ300x (Athena Top End) with tuned KYB suspension. I noticed no detriment switching back to WP, and felt the 2020 was FAR and above the best WP suspension I have ever owned.
Great video and channel and thanks for putting these things out for public consumption.
Great to hear you had no problems. Dave mentioned there have been 17 maps for the 2018 to 2021 models so I wonder if part of the problem is they were still tweaking maps in production runs? It could explain why some 2020 and 2021 have had premature wear and even seized from a lack of oil, and others haven't. I'm hoping the 2022 uses their most recent 'extreme' map or another one with more oil across the rev range.
Thanks for the info. I was thinking about getting a TPI next but I'll do more research first. 💪
With luck it will be just like fuel injection for four stroke bikes, they'll iron out all the issues and eventually it should be very reliable for everyone.
Yikes! I believe i'll stick with carbs (for now).
yikes! carb bikes
Thanks for a great summary!
Our pleasure Dave, credit goes to Dave from TSP for a lot of work he put into this.
Great video and thanks for the heads up. 👌
No problem 👍
I have a 2017 XCW300. I mix 60:1 and that’s it. In 2 years I took the plug out, looked at it and put it back in.
I am so happy to still have a 300 from 2017. Running with a Smartcarb and i nearly beat the guys with tpi in fuel consumption also.
I have a 2018 and haven’t had any problems. Ran it stock for about 40 hrs then Switched to a GET ECU and a high compression head. Will probably rebuild this top end around 120 hours. It’s been a great bike for me. I personally like the linear powerband.
I would inspect your cylinder.
@@johnhoward4977 Cylinder looked great.
Great to see manufacturers thoroughly testing their products before release. Not surprised really.
It does seem to be a regular problem with KTM. 😢 And sometimes their suspension mob too.... e.g. the WP 4CS forks.
@@crosstrainingenduro yes agree. I bought a new 300EXC back in 06 and the suspension both ends was stictiony and didn't work all that well. I recon an old DR250 had better suspension. I'm not a fan of gimmicks and I think WPs needle set up was just that. Who wants a needle cutting off the damping and in effect making the suspension solid just as you need it on the big hits. And it was 5 speed and all dirt bikes need 6 gears imo. Hell, even my old IT and my TTR230 have 6. Rest of that KTM was damn good though. It went like a rocket.
TPI runs very well! I ride 2019 Husky
Mine too! 2019 Husky 250 (with flywheel weight. And 1:150 to 1:200 premix, which might or might not help or hurt. 90h/2200km. Stock suspension is far of optimum for any type of riding)
Great info! I’m sticking to carbed Betas. Frick tpi
I’m sticking to my 300XC with Smart Carb. All the advantages of TPI without the complexity and problems
@@jjjjjjjjrifufjssjosskenf same but Lectron.
I have an older bike with the new Billitron carb on it and it makes more power gets same mileage with a lot simpler setup than TPI.
I have a ‘21 TX300i with the TSP low comp billet head and remap and it’s been faultless! Can not recommend the TSP upgrade highly enough. Dave is a wizard!
Great to hear. I've heard so much positive feedback about TSP over the years I had no problem trusting his info for this vid.
@@crosstrainingenduro yeah he’s been very helpful to me. I’ve contacted him directly a couple of times with some questions and he’s always been quick to respond and non biased in his responses.
Clean your spark arrestor screen sooner than a carb 2T. A clogged spark arrestor screen will cause severe stuttering/missing at low and high revs. That was the case for my 2021 TE300i before I knew it needed more frequent cleaning. Unforntunately the ambient air pressure sensor on my bike came from the factory with the "nipple" broken off, so it could not do the swap test. Although the pressure sensor was not a failure on my bike so far, I bought a spare one before they went out of stock again.
Where do you live where spark arrestors come factory? I have a 22’ TE300i
@@stevenllewellyn8906 They don't come factory. But are required in all public forests in Washington State, and most of USA. I've got the Enduro Engineering end cap/spark arrestor. Another popular option instead of a screen is to replace the entire silencer with an FMF Turbinecore which acts as a spark arrestor but is more expensive -- requires less cleaning.
I bought the very last carby model brand new 250 EXC in Australia in 2018 and it has never missed a beat, no mods either. They tried to talk me into the new TPI model but I said "it's a dirt bike, the simpler it is the less troubles I will have". No issues since new.
Awesome bikes, a mate of mine might have bought the second last one then. We tested it side by side with a TPI which had the $1000 treatment from TSP... no contest. The carb model was way more powerful and responsive.
150 exc tpi is in my list, but listening their horrendous story had made me considered in getting the yz125x. Can't wait for October to come😴🤔
Easy fix use a carb I run beta 300rr torque low down is nuts I love this youtube channel the tips and tricks is brilliant
Apart from the main bearing issue a few years back the RR engines really are a work of art when it comes to grunt.
@@crosstrainingenduro friend had constant problems with main bearings on rr 300 on 2021 model
Did Beta fix it under their extended warranty? I hope so! It was crazy they let the problem continue for so long...
@@crosstrainingenduro dont know the details about repairing
Cool music, Barry.
So, on my 300 xc-w with pwk I'm getting smooth running at low rpm low slide opening cruising, crisp throttle response, roaring top end power, and 34.4mpg average consumption. I'm pleased.
Cheers!
That's impressive fuel economy for a two stroke!
@@crosstrainingenduro
Right? It's a lot leaner now than how it was delivered six years ago!
I know there are smaller companies out there that have 2 stroke motors but I'm glad one of the big companies makes a two stroke. Wish the big 4 would get back into it. I'm sure they would have no problem making a TPI or even a direct injection bike.
Yamaha never stopped! They don't make an off the shelf, hardcore Enduro machine but I see lots of modded YZ's in the bush (flywheel weights etc) and they do pretty good!
We were really hoping the YZ250X was going to be developed into a proper enduro bike but no such luck. Everyone I ride with said they'd snap one up if Yamaha went to 300cc, put on a hydraulic clutch, gave it six gears, an electric start and put the road gear on it so we could register it.
Great video! Taking lots of notes here... My first dirt bike is also my current bike, a EXC300 TPI 2020. So far only done 38h on it due to Covid lockdowns and work taking turns in ruining my life.
Questions though: Where does one acquire said 'Extreme Map'??? Is this something I should ask at the dealership? What's the process?
Cheers!
That was a service bulletin to all of KTM's dealers... so yes, you'd see your dealer. Not sure how the process works. I hope they don't charge you!
@@crosstrainingenduro Thanks mate! I'll give that a go then. The 'no charge' bit I'm not too hopeful... I mean, this is KTM. The dealership that actually charges for the '1 hour service' haha
Out in the wild yesterday we were all discussing that TPIs have just made their way into thailand and wether they were a good idea for use in the wild.
Thanks to your video Barry ill be keeping the CRF and later on buying a chinese KTM. :)
The majority of TPI riders don't seem to hit problems but a significant number do. And they do seem to run smoothly when they are right... the remapped ones I rode in Romania were all fine.
@@crosstrainingenduro i think ill still buy a chinese KTN and with the money left over have 3 more for spare parts. :)
Still got my trusty 18 300 xc carb, went to Keihen, big improvement but after seeing a vid , Smart carb vs TPI my interest was sparked.
I would most likely buy a TPI if i was upgrading but really cant justify the coin so SC2 inbound.
Bloody expensive to get in Australia but still way less than a new bike and having to do the suspension again.
We rode a friend's 2018 carb back to back with a 2021 TPI and there was simply no comparison. And this was after the TPI had a custom cylinder head and aftermarket ECU fitted to try and get better grunt. It was such a big difference we are still wondering if the TPI was simply a dud bike.
Rode a new TPI yesterday very briefly. Felt 'weird' in power delivery. But I just assumed it was different than my carb model and not 'bad'. I'm sure I'd get used to it just fine. It feels softer in power but I think that is just inferring smooth power delivery as soft. My carb 300 definitely hits harder up top though.
We mainly noticed the lack of grunt when we rode a carb 2018 250EXC back to back with a Gas Gas 2021 model... and the TPI was already remapped and had an aftermarket head! It was way softer than the carb at low revs.
yeah the TPI is better than a carb for hard enduro bacause of the softer but very predictable power delivery=more traction.
Holy shit! I was going to buy a new KTM 300 this year but now Iam thinking a WRF450 will be a better option. Great vid, thank you. Love ya channel.
As per the vid, most owners probably won't hit problems.... especially if they get the 'extreme' map KTM has issued to try and get the system using more oil. All the known issues in most brands only pop up in a limited number of cases.
@@crosstrainingenduro that’s true mate.
I’d recommend the YZ450FX
@@fentonpainter7907 I got the WR. It came with road reg which sealed it for me.
I rode a TM300 with a Keihin PWK. It carbureted and delivered power so well I would never need EFI.
That's because TM makes sure their bikes work before releasing them to the unsuspecting masses.
What is the optimum TPI engine operating temperature in freezing cold weather?
Tech is supposed to make life _easier_ isn't it? Call me a Luddite, but I recon a Lectron carb is a sound investment. I can with live the pre-mix life.
Greetings fellow Luddite! I, too, enjoy the hell out of my 2018 te300 carbed with a Lectron! That bike is a keeper.
Yep, I have no plans to go for a fuel injected two stroke until it's problem-free and as maintenance-free as a carb!
100% agree. Lectron all the way. 200 plus hours on a 300. No issues.
I have lectrons new Billitron and it is worth the money.
My yz125x equipped with a smartcarb is amazing and so simple.
Good evening lads, im looking to get my first Te 300i in the very near future however as a new rider thinking of getting a second hand one, will get a 2020 or newer are their anythings i need to be wary of or think about?
I think all the things in this vid would be the main issues, David.
I have the 22 and have almost 60 hours and so far so good
I assume they would be putting the 'extreme' map on all 22 models?
Within the first minute the comment about the 2017+ carbs is all about the #4 slide that they came with. Have it cut to about a #5.5 or buy a 2003 (i think) CR125 slide which is a 5.75. A "2 or "3 Kawasaki, not sure which, is a #5. Having the stocker cut is cheaper. But it leaves you down for a while.
Good info. A bit naughty for tsp to list their own product as an solution. Good product but there are others aswel. And is it possible or recomended to run tsp (or other head) without mapping?
Actually it was my decision to include a mention of Dave's stuff. He never requested this and in fact I told him I wasn't going to. But he put so much time into this I decided to give it a brief mention. Are there others doing remapping in Australia?
And tbf. Tsp do really know their stuff and have some excellent products
Are the '22s any different from '21? I notice my bike has extreme oil efficiency... hope it doesnt back fire! Have 30hrs on it and its still crisp as new.
I don't the specifics. Apparently they are making adjustments even within specific years. All I know is they always use too little oil....
GASGAS ec300 2021 model been driving 190 hours without doing any with the engine except 2 x oil pump change and 1x Crank case sensor and made a tIdle screw.
Planning to drive it a 100 hours more before rebuild the engine., like a loong time test :)
Great to hear! Did you get your dealer to swap it over to the revised map that uses more oil?
@@crosstrainingenduro Asked my dealer about this 2 times, but was told it came with the newest map and this should not be any problems. I'm pretty sure people who have oil problems have been using premix oil and not oil made to be mixed in the engine. Here some call it snow mobile oil, more liquid and made for mixing in the engine.
Never had any problems even while driving in - 25 degree C
But boring/hopeless to drive a 2-stroke on the road, so bought a GG 350 F to. Good to have two bikes.
Feel some difference between this two bikes, 2-stroke are more agressive and feels lighter to drive, my pulse belt tells me the same 10 HBS lower on the 2-stroke, but same time around the track.
Man I love my Beta's:)
Don't get me wrong I love all dirtbikes but my buddy has a 2021 300 KTM and it is a really sweet bike but he is frustrated that he had to stick so much more money into the bike to get it to perform the way he prefers, like a carbureted bike. He also converted the forks to springs, way better according to him.
It can be an issue with various bikes. I remember buying a near new KTM 690 years ago and then found out I needed to spend close to $2000 to get it running right. I'd already paid so much I just sold it. Hopefully that's not the case with recent models.
I was a little nervous about oil injection on my bike. Don’t think I’m gonna go to TPI anytime soon. I can usually fix a carburetor issue on the trail but I can’t replace a sensor.
That's like saying I don't want fuel injection on my car because a carb is easier to fix... How often does your fuel injection on your car need parts replacing?
I think the difference though is that we've had many years of mainly trouble-free driving the majority of cars with fuel injection. And mostly the same on road bikes for a long time now. At the current rate it could take a fair while before all issues are fixed and then for the long term reliability of TPI to become established.
@@supernovadw Good point but tpi on 2 strokes is still pretty new…and when a sensor goes bad on my truck I can call a tow truck.
@@davehowe_just_an_old_dirtbiker when sensor goes bad bike just isnt 100% crisp anymore but can still easily be ridden. Few times people didnt even know sensor was faulty until sopmeone else tried their bike
@@crosstrainingenduro The other thing to note too is that I was around during the conversion from carbureted cars to FI and I don't recall engines seizing in the cars. Like you said, once they work out the bugs it will be a winner but until then I don't plan on being a guinea pig!
Are you shure with the crank bearings ?
My friend from Bosnia had to replace them at about 240h. Before he was riding a 16´ 300, that is still riddin by a friend that got 600h without crank bearings replaced. I would say riding style didnt changed this much.....he said its because the fuell mix didnt have to pass the crankshaft and so lubrication is not that good like on carb bikes
Me? I know next to nothing about mechanics. But this is coming from a specialist with years of development and work on two strokes.
You forgot no kickstart. Lol. I'm out on that one. Love the vids
Moral of the Story. Stick with CARB👍🏻
I bought the 2021 Gas Gas 300 tpi model. I trust ktm but if these issues show up I'm going Sherco or Beta with a carburetor .
Thanks for a good summary!
is the oil issue solved on the 2022 model or is a "extreme" map still recommended?
I own a 22 model also and would like to know this as well ...Only issue I had was a dirty CCPS which caused bogging. Mine had dirt on both sides off the small o-ring inside the trey around 10 hours. I ended up cutting the trey out and secured the hose directly to the CCPS using different hoses and fitting which has completely resolved the problem, bike has close to 40 hours now.
BTW love your videos, keep it up
I absolutely love my 22 300xcw, but it’s my first bike, so I’m relatively clueless to many of these issues described. I’m at 15hrs and I think* the bike has been flawless so far. I have a Slavens idle screw that I’ll install at some point and will inspect the cylinder and the spark plug whilst I’m in tear-down mode.
@@huskynick7562 Good idea regarding direct hose to the pressure sensor
No idea yet, Peter. I hope they put the 'extreme' map in. And apparently they'll do something new again for 2023 with a TBI setup instead.
I think the main potential problem would be the mapping if it didn't come with the 'extreme' map or some equivalent that uses enough oil. Maybe check with your dealer, John.
subscribed dear!
keep it up
Thanks, will do 😊
Great vid and great tips!!!
Can you share, where the vids were taken in Romania? Cities, locations?
Actually, very nice places to ride!!!
Hope to meet you there someday!
It's all the same tracks as used in Romaniacs, Michal. So in the countryside around Sibiu.
@@crosstrainingenduro
Thanks, Barry!
Can you please recommend any contact person to organize a trip there? It is a little difficult to ride "legally" in the mountains, as there are some new restrictions in place. Thanks!
I went with Carpathian Adventures, Michal. They are based in a renovated farmhouse in a village about 20 minutes from Sibiu, right at the start of the tracks. Most groups are actually based in Sibiu which suits if you are into the nightlife etc but you have a fair bit of road riding to get to the tracks. My guides know most of the other groups and say they are all genuine locals who will look after you well and ensure you don't get into trouble with illegal tracks etc. www.carpathianadventures.eu

Great! Thank you very much!
I'll surely contact them to organize something for the next year.
Wish you all the best with you channel!
When the pressure sensor reads high it runs rich and the spluttering starts you also lose power everywhere, when it reads low it runs lean and does the top end bog thing (runs out of map/ empty cells?).
I have 13 CCPS and use them as tuning dongles (electronic jets) I'm about 30+ meters above sea level (14.6 psi) and my senors read 14.1 for the 5 black China sensors and 14.2 14.4 14.5 14.6 14.6 14.6 15.2 15.2 a mix of KTM and China grey sensors.
I mix and match both baro and crank case to get it just right. Start with a middle range baro 14.4-5 then find a crank case one that gets it running pretty good and fine tune it with a baro sensor.
You can't have a large difference between them or the ECU gives an error code.
My bike seized 2x and probability a few minor ones in between, I think it's sticking check valves in the pump. I replaced mine then it was fine after that.
Might as well be jetting a carb lol.
That's a lot of experimenting! What year model is this?
@@crosstrainingenduro 2020 EXC150. Not that bad to do, just it only lasts a few rides or less untill the sensors start reading different. A lot of TPI's out there spluttering and the riders don't know any better.
@@Andy-co6pn At least with a carb I only needed a needle change between winter and summer.
Maybe adding a little oil to the gas in the tank as cheap insurance. Manufacturers probably have to run the gas oil mixture as thin as possible due to emissions regulations.
Waste of time. Fuel is injected straight into the transfer ports, which in turn lead straight into the combustion chamber. Therefore bypassing anything and everything that needs oiling.
I have a 2022 300 TPI and previouly a 2020 300 tpi. The 2020 had a heap of issues was an absoulte lemon. The 2022 with the new map is definely leaps and bounds better, The key I have found is starting procedure, I run the cold start out on my at first start until temp reaches about 34 degrees celsius. Turn that off then ride around easy until it reaches operating temp around 60 deg and the thing runs perfect all day. I did run the TSP kit on my 2020 but due to me not following that startup prodecure it would foul plugs and run shit all day.
Never heard of this starting procedure, but its likely this is done anyways, as no one starts a bike and runs it without stop the whole day ;-)
@@hachtenduro7824 I only do this on the intial start up for the ride, its fine afterwards even if you stop just not initally when its cold.
I did the tsp kit before I even had an hour on my bike. It made it run a lot better (carb like.)
How do you know?
@@hachtenduro7824 Because the bike had major pipe bang. That's why I did the kit. I didn't want to ride it the way it was.
@@seanwahl1000 I understand, it sounded like you did not run the bike at all without the mod ;-)
@@hachtenduro7824 .8 hours. I had enough of that surging pipe bang.
Hi friend i have a problem with my new husqy 250ti when i whellie with my bike it cut the gasoline how can i solve this?
I've never heard of a 250ti model. Did you mean TPI? I haven't heard about this issue.
Have you done a video on age ,injury and risk ?
I think it's been touched on in most of our vids that discuss injury and risk, Dave. But at some point I might do a specific vid.
@@crosstrainingenduro Let me know if you ever come to Washington State we have THOUSANDS of miles of single-track from rain forest to sand dunes to desert. I would pay for one of your seminars !!
Anyone know what the 2022 models ship with from the factory for ECU mapping?
I know yet, but I hope they get it right. So many have paid top dollar for their 'ready to race' bike then paid hundreds extra to get the mapping sorted out.
My 22 xcw has 144 hrs stock bike with idle screw and I’ve never had a problem.
Let's see this 😆
I have a KTM TPI 250 and have never experienced ANY of these problems at all. The bike is as it came from the dealership, with just an FMF full exhaust.
It all depends on whether riders thrash their bikes or not.
Actually riding style doesn't appear to have any influence for many of the issues... although if a 2020 or 2021 is going to seize it will probably happen faster if ridden hard. And issues such as fouling plugs or spluttering at low revs happen more for the casual riders...
@@crosstrainingenduro or perhaps some of those bikes are just lemons 😁
20 hours in and suddenly fouled 2 plugs. turns out was the CCPS that went bad. Swapped it out and a week later and 3 rides it fouled another plug. considering selling the bike and going back to 4T
Some riders have zero issues with CCP sensors, others have multiple run ins... I'm not sure why. It gets expensive in Australia as they are AUD$171, about four times what you pay in for the genuine part in the USA.
That's a ridiculously long list of mods required on a brand new $10,000 bike that should run properly from the factory.
Our personal opinion is they needed to do more testing and eliminated issues... or at least reduce them. But then KTM has been accused of this in the past. It's great they innovate more than most brands, but sometimes the customers become the lab rats. Or they can feel like that.
@@crosstrainingenduro To KTM's defense though, they were practically forced to introduce the TPI due to new european emission laws.
Can you talk about husqvarna 2020 cracky subframe and solutions
Probably not a serious enough issue to warrant a whole vid, Miguel. Most brands have niggling little faults like that.
The solution is…. Don’t loop your bike or smash it into the floor.
@@crosstrainingenduro Thanks for the reply and keep up the good content.
@@jamesmarchant5837 that's easy for a hard enduro rider ahahah. but a friend broke his subframe just pulling the rear fender.

Good to hear you've had no issues, Garry... that same for many TPI owners. I made this point in the pinned first comment:
"Not all TPI owners will have problems, in fact the majority have no issues. But there's a significant minority who do. We have compiled info from two specialists working in the TPI area, and confirmed with other mechanics and industry insiders. Then finally we looked at various cases reported online. Statistically it's likely that you won't have problems, or your riding buddies too. Remember main bearing failures on Beta two strokes? It occurred in roughly 5% of cases, so most riders had zero problems. But a significant number did. That's often how these known issues work. Sherco riders have similar problems with regulator and ECU failures etc."
i see，sherco and yz250x best choice now。tpi bike need more years waiting。
Sherco have quite a list of known issues too though. czcams.com/video/yoaaUiJWLTQ/video.html The main ones that stop the bike are regulator and CDI problems but hopefully they are rare now.
@@crosstrainingenduro oh…..so what about mr300.
Already did a video
I've got 110 hours on my 2020, showing no signs of wear, will be doing a rebuild at about 120 hours.
I know 5 other guys with 2020's all with similar hours no problems at all. It obviously depends how you treat it. Don't go flat out till she's nice and warm. Clean your oil screen etc.
I'm sure 2 stroke performance are good, but they do have a vested interest in selling remaps. For the average rider (99% of us) who is not a mechanical moron, there is no need to remap. My 2c
Another option is to just ask your dealer for the 'extreme' map, Luke. In some cases dealers try to charge for this but often they'll do it for free because they know there have been issues with premature wear and even seizing. Certainly a lot of guys have had zero issues, other have. KTM has released 17 maps to date so it's possible they vary these even within a specific year... certainly some of the have used very little oil e.g. as little as 150:1 at certain revs.
I'm just waiting for the day ktm makes a detuned tpi dual sport I'd pay extra for one too
The TPI bikes are not as reliable as the carb versions. Stock, the bottom end power is much softer. The oil injection fails in cold weather operation at startup as the injected oil coagulates on the reed block. The Crankcase Pressure Sensors fail frequently. The worst part for the consumer is that replacement parts are not only very expensive, but often out of stock. Waiting for months for parts for your $10,000 dirt bike that seized in less than a year old is extremely frustrating. KTM/ Husky has done a poor job of taking care of customers with their 30 day warranty. Hopefully you will have better luck.
I've heard from both Australian and USA mechanics that accessing top end parts has been tough due to the number of seizures. I just hope that KTM is offereing goodwill warranties that extend well beyond that paltry 30 days.
Mmm...sx 250 with 300 topend keihin carb 160-165mainjet 35 pilot nozi or nech(suzuki)throttle needle on 2nd clip ....very very reliable very very smooth and very very strong bottom end torque
Wow I'm glad I don't have a TPI KTM lol
my 19 husky tpi 250 has 150 hours on it right now and has not been rebuilt or had one singe problem yet. I race hare scrambles and beat the shit out of the bike pretty bad and still have not have to repair one thing mechanical yet.
As the vid says, they are generally reliable especially if you are aware of the issues and make mods as needed. But the failure rate can be high: e.g. top end parts have been scarce in various countries due to the number of warranty claims for seized 2020 and 2021 models according to relevant dealers and mechanics.
I’m glad I don’t have a ktm 😭🤣
@@exoticxenon5005 lol kinda weird that I personally know like 20 to 30 guys from my local woods spot and not one have had any of these issues this video speak of 🤷♂️ all of the bikes are 19 and up to 2022, most of the issues these bikes had were on the first gen tpi bikes
@@huskyboystv1806 my 17 RMX has somewhere around 150 hours or so (2600 miles) with zero issues. I shimmed the valves at 100 hours, the bike runs like a top. I don't race the bike, I just ride technical single track.
I met a guy in the woods with a brand new 22 husky 300 he said he was taking it back to the dealership because it was leaking oil. I would be pissed if I bought a new $10k bike that leaks oil. I'm kinda surprised Barry didn't mention the power valve leak with the new KTMs
EFI 2 stroke,best thing since sliced bread.I've had 2 TPI bikes, 250 and a 300...600 hours in total.Only minor issues.Never going back to carburettor again to deal with premixing,fouled plugs,rejetting,bad fuel and oil economy, and leaking when i lay the bike on its side...Or when you go downhill with running bike or doing low rev technical stuff and now you twist the throttle and the bike just sputters and you won't make the hill and don't have the power when you need it.No thanks.This doesn't happen with a TPI.
It definitely has its advantages and with a bit of luck it will get more reliable in coming years.
Just sounds like a pain in the arse ill stick with the old trusty keihin carb 👍

@@crosstrainingenduro been dirt bikers and lovers of motorcycles we are reprobates and law breakers and problem with authority PMSL
Idle screw mod not needed, just fitted to cover other issues, i.e. a bandaid fix for something else which is wrong
All of this comes from someone trying to sell you parts. I have over 700 hours of TPI experience between three different bikes and they run great. I did one top end at 80 hours and they look just like the top ends I did at 150 - 200 hours.
Dave from TSP does sell parts but he's well known in the industry for providing objective useful advice to many two stroke riders, Bryan... I wouldn't have collaborated with him on this vid otherwise. If you explore the forums you will see all these problems are very well documented by actual owners who aren't selling parts. And yes, there are plenty of TPI riders with zero issues. But there's a significant percentage encountering problems.
@@crosstrainingenduro I don't believe much that's posted on internet forums, most of the people that post on those are full of crap. I'm sure there are people that have had problems but they aren't as wide spread as they make it seem. Out of all the people I know personally that have TPI none of them have had any serious problems.
👍👍👍
I have a tpi and the fueling has been fine for almost 50hrs but I've had issues with the starter and clutch 🤷♂️
It just doesn't rev.
Doesn't get high rpm like the MX model can.
They should get a direct injection with high intake gas pressure like in the car engines for example.
Indirect injection is not the key.
My only problems with TPI (owned a -18 & -21 300exc) is the CCP goes bad and the mod for an idle-screw.
As I understand it TPI was and is a Euro enviro issue .Also TPI makes sense for machines that ride in various altitudes and extreme temps , but for us flatlanders I just do not see the value or payback.
I can climb up 9,000 ft above my city of Monterrey and the Lectron carb still works near perfect. So I am going to wait another year before swapping my 2014 TE 250 Husqvarna, makes no sense to fix what is not broken. Maybe TPI runs smoothly, and has engine balancing to reduce vibrations. That’s it.
@@rogermty1971 Agreed , both Lectron and Smartcarb seem to be a wise choice for a Kehin replacement . As for the new balanced engines yes they would be easy to get used to , but would still not make me a better rider. lol
My 2019 Husky 250 TPI runs well without any mod right from purchase. I have a flywheel weight, which I like. I run 1:150 to 1:200 premix, which might or might not help or hurt. 90h 2200km. I bought it, because it would not loose gas to the environment soil when you drop the bike.
Dave's info seems to suggest the 2019 mapping used enough oil to not worry about seizing or premature wear. But if you aren't fouling plugs then it won't be hurting the engine either. Initially when 2020 and 2021 models were seizing he suggested adding oil to the fuel as a stop gap measure while they figured out what the problem was.
@@crosstrainingenduro
Thx! I had only one fouled plug after approx 50h of operation. It occured at cold start, mild ambient temperature. Starting with no choke and immediately coasting to the course. This never happened again. I run the Iridium plugs still.
My reason for premix is, that I see a possible risk of short failure of the oil pump. If that happens, fuel will wash away the existing oil film like a degreasing agent. This is impossible with little oil content in the fuel.
My TPI issues were permanently resolved by a Beta
Yes bro check my new one out
yes you get keihin which is a plus but debatable. but then you get everything else much worse than ktm
@@maucina12 not at all lol do you even ride u ktm fan boys make me laugh tpi are co.ing back to shop for rebuilds at 40 hours from new that's worse than any other bike I've rode
@@1991enduro hard to judge people on the internet just based on comments. I am almost 500 hours on my tpi with no problems except 40 euro sensor, but not saying they never go bad. All bikes have faults. Betas main bearing problem is unfortunatly very often. And you cant say beta suspension is good
Just by a Sherco, problem solved!
Well they do have their known issues too. Recently we looked into poor jetting, fouling plugs, poor ECU mapping, coil/regulator failures, idle speed stepper motor issues, clutch return springs breaking, poorly fitting plastics and bendix failures on earlier models. All brands have their known issues when you start digging. czcams.com/video/yoaaUiJWLTQ/video.html
Part of two stroke ownership is "simplicity" if you are going to be pissing about with injectiors, oil pumps, fuel pumps and sensors then you might as well be on a four stroke!
And the interesting thing is the KTM four strokes are very light now... and the TPI system adds a fair bit of weight to the two strokes so there's not much difference now.
@@crosstrainingenduro I've moved to Yamaha after 20+ years of Orange. TPi was the deal breaker for me. Sold my 300 and got a brand new Yamaha WR450F 2021. Ace bike. So tunable with the power turner on your phone. Alot cheaper than a KTM also and great spec.
Sweet! I've always had a soft spot for the WR after owning a 2006 model. I'd love to see Yamaha develop an ADV model, heaps of riders do their own mods with the blue bikes.

As with most known issues, the majority of bikes will probably be fine, Con. We don't know exactly what rate of 2020 and 2021 models are seizing, but it's in the minority.
@@crosstrainingenduro most definitely it is a minority dude. i am just glad that the ktm group is putting in time to advance two stroke technology with fuel injection etc
It always is e.g. when I highlighted Beta's main bearing issues I did point out it was occurring in roughly 5% of cases. KTM has never mentioned any stats for their warranty claims though. It would be good if KTM put more effort into thorough testing before releasing their models. czcams.com/video/kxCHcoHEEBA/video.html
@@crosstrainingenduro i think with the past few years alot of manufacturers are just trying to get models out the door before doing enough testing and hoping the consumer does the testing for them realliy. you see this alot more with cars as well
I’m not lying when I tell you that in the US the most reliable most refined year of the husky’s is the 2019 just before tpi.
A friend of mine bought the last carb KTM model as he suspected things might go downhill with TPI. Awesome bike to ride. They almost got those 250/300 models under 100kg until TPI kicked the weight back up again.
@@crosstrainingenduro it really took the fun out of owning a 2 stroke for me. It smoothed out the power very close to a 4 stroke with not as much hit from power band anymore.
The ones I've ridden have had soft bottom end power... except the ones in Romania. They'd be remapped by one of their local gurus and felt closer to a carb model so it seems it can be done.
@@TheRossillini yep I'd agree. Flat feeling. Lost the zing and less torque low down. Haven't tried the "extreme" mapping to be fair however.
My tpi 250 2019 have 430 h ...no problems hah
No issues and talking to TSP won't give you an honest real answer as they are out there to sell a service.
My 2019 250tpi has been absolutely perfect out of the box with zero mods.
Explore the forums and you'll see all these issues well documented by riders themselves. Dave put a lot of time into developing this info with no expectation that I would mention his stuff too. Not everyone is having problems, only a significant minority. Your bike running well doesn't mean others won't have problems. Again, check the forums.
@@crosstrainingenduro yes exactly, check the forums and you'll get tons of reports of people moaning about their TPI's!
1) Bad news spreads! 100 people with good issue free reliable bikes won't say anything, 5 with issues will go out their way to post online about how bad the bike is etc...
2) Majority of issues with tpi come from people messing with them, fiddling with ECU, powervalves etc... Leave the bike stock standard they are solid, reliable and powerful bikes
Yes it's a small but significant percentage. No, many are facing issues without messing with their bikes. I don't rely just on anecdotal evidence when doing vids about known issues, but also discuss with industry guys. When I reported on Beta main bearing issues I had this kind of response from brand loyal Beta riders....
"My bike is fine. So is my friend's. Those other guys must have drowned their bikes or ran them out of oil".
And of course eventually Beta acknowledged there was actually a problem, something the insiders (e.g. Beta mechanics and dealers) had been telling me all along.
@@supernovadw I know plenty of people on TPi bikes with issues. No smoke without fire as they say. Oil pumps, CCP sensors being the most common. Oh and crap WP suspension on all of them. I own a 300 too. Not TPi however, friends bikes put me off if I'm honest. Lectron all the way.
Green-Enduro is becoming quite an expensive hobby.
TPI sounds like technology for technology's sake... the benefits are outweighed by the problems and often limit trailside repairs/adjustments... if the performance is very similar why bother stressing yourself out with excessive cost and complexity compared to a carby... simplicity is best and far more reliable/serviceable. If you really want TPI wait till the factories work it out properly.
Some claim the TBI setup will regain that lost grunt at low revs. But I think we'll still have the needless complexity and so many little things that can go wrong.

It would be great if the every bike was problem-free when you look at the cost, Edith! But unfortunately all the European brands seem to have known issues that can pop up.... see our known issues vids for Beta and Sherco. And if some Japanese models don't have problems, it's often simply because they haven't introduced any innovations for so long. 🤔 Having said that, I think KTM should have done way more testing and had far fewer problems with TPI...
