I 100% went to two strokes because of fuel injection. I was 4t-for-life prior to TPI, because I HATED having to pull the carb to rejet all the time.
I’ve jetted all of my two strokes exactly once. JD jetting kit…done.
@@gpaull2 Well good for you. I still hate carbs.
I just bought my first 2 stroke in almost 4 decades - 250 XC-W. I wanted FI and no oil mixing, otherwise I would have just bought another 4 stroke. I love pulling up to the gas station with my bike on my motorcycle carrier, and then fueling up both the car and the bike at the same time, and not having to monkey with a fuel can in the car.
Hello Kyle! Loving the videos! I'm a newbie that just got a 23 250sx so I've really been soaking up and studying! Thanks for the help!
My old '18 with a Billetron and head runs absolutely perfect, so smooth from a crack of throttle and tons of power. It lugs so so well and with the radius cx it's just amazing.
I love my 23 300xc. Absolutely love it.
Another great video!
I decided to go with 2023 TPI husky instead of TBI, because when I saw that 95% of elements are new I thought, great, so I am going to be testing if 95% of the bike works correctly.
You'll be fine. I love my TPI. I have 150 hours and only had to replace a CCP sensor which was about 45 bucks. Is TBI better? Probably....but I'm not going to keep forking over 15K every time a new KTM comes out....its ridiculous. For your average rider TPI works great. Super smooth...
@@davidsalinas5508 exactly... incremental improvements and everyone poo poo's what came before it and has to fork out more cash to to have the latest tech. I have a 2022 TE150i thats tpi and it has been flawless for me and I absolutely love the bike and its engine.
@@davidsalinas5508 Totally agree with you. I own both TPI and TBI bikes and the TPI's are great. The TPI is super tunable as well and they run amazing! The TBI's are super nice though... Both are winners.
First off, i love the content about these 2 smokers. Had an 05 KX back in the day and although it might not have been tuned perfectly, I still feel it ripped and loved racing it until my accident. Carburator, didn't bother me, Mixing didn't bother me, but losing the strength in my legs and not physically being able to kick start anymore is why 13 years after my accident I purchased the KTM 300. If Kawi made an electric start KX 250, i'd buy another one. Just love them 2 strokes.👍
You are soooo right about mixing fuel... I had a cr 250 2 stoke 1999 and a kx125 2 strokes... yes its "fun" the mixture process, but its a lot funnier not to bring your measuring cup and I hated seeing my buddies on a 4 stroke waiting for me loll. Tomorrow I'm picking up a 2024 husqvarna 150 TE for my wife and maybe 2 weeks after my 2024 ktm xc-w 300! It will be my first fuel injected bike!! So cant wait to see the improvement on those bike!
i have a 2022 TE150 and it has been flawless for me and its not TBI. I guess Im one of the lucky ones
I usually just pour the oil into my jerry can at home, then fill it up with gas on the way to the ride, takes about 30 extra seconds...
What you said about people moving to four strokes from two strokes because of the tuning being a barrier of entry, is exactly why electric is going to dominate this space.
My 2018 ktm 250 xcw carb model with jd jetting kit in it runs flawless all year around from -5 to +30. I set the jet once and never touch it again. From comparing with friend it still has more power than any stock tpi 250 bike.
Maybe not tbi injection tho…
I was tired of jetting and mixing gas, so 4 stroke I went. I actually missed mixing oil and the extra fun of a 2 stroke so eventually I went back to 2 stroke and kept the 4 stroke.
Mapping and porting differences. Not just mapping. Highland cycles is about to review an xcw with a TSP head and flash. That will answer what the xcw motor is capable is changing mapping only.
You mentioned the words big bore referring to the 300's. What I read was that KTM has a plan for a big bore next year which will be a 390, which sounds good because a 300 has limited power compared to a real big bore.
When I hear big bore I start thinking more in the 500 range. 😈
LOVE my two 2023 KTM 250 XC bikes. Currently have less than 11 hours on each. Have to change spark plug every other ride, as the BR8ES is fouling. Local KTM shop says switch to BR7ES for trail riding. Comments ? Thnx!
Honestly, I hate carbureted bikes! There I said it.
Is it bc you don't know how to tune/maintain one? If so a smart carb or lectron is for you . (Even though carbs are simple and bulletproof)
I have the original Cast version Smartcarb on my YZ285. It’s awesome. No jetting just a Metering Rod. It can be adjusted on the trail / track. Super easy. With that being said I’m gonna get a 24 Husky TX300 next year 👍
To me, carbs are fine but I have to mess with them way more than the EFI bikes. I just get tired out the jetts clogging and all the stuff. No worries with fuel injection
@@davidsalinas5508 Correct. My first generation Smartcarb has no jets just a metering rod. They say it’s the next best thing to fuel injection plus I bought it when no 2 strokes had EFI yet
Just watched a video with a dyno and the tbi bikes only make 27hp and there was huge differences some bikes ran nice making 32hp so like crap
What you didn't mention is that the lean condition on the Tpi made the engines run hot and destroyed a lot of topends. The Tbi is a much smarter system overall, just wish they hadn't deleted the Kickstart.
Kyle you should try a tsp kit for your xc. They have 3 different tunes so you can get it tuned for your liking.
GOOD STUFF KYLE! GREAT JOB!!
Dirt bikes are so far behind! 2 stroke snowmobiles have been efi for a long time. Still riding a 98 ZR 600 efi lol
I’m gonna get the TSP TBI Power Kit ( high compression head & ECU reflash ) for my next bike a 24 Husky TX300. It cleans up the fuel injection and more horsepower ! 👍
You better ride the TX first, I think you will find that you don't need to waste your money to get more HP. Not even really good A riders use all the power a new TBI TX can deliver.
Let me know how it goes for you and what time you get. I have a 20 xc with tsp kit and I love it.
@@coalcountryrider Everyone loves it on all the CZcams videos 👍
So how does a lectron or smart carb compare?
I've run all the lectrons on my 125/150/250 as well as mikuni and kehin. The TBI is really really good stock, and I have worked on the carbs till they're perfect. I think TBI is better out of the box but I have my kehin better on my 150 currently. Could never get the lectron that good but then again I have a custom needle and the stic on that bike.
Looking forward to tuning tbi with the TSP ERM
Can anyone explain what’s going on with TBI’s and them running rich fouling plugs and loading up constantly. Every single tbi ride with that is stock won’t stay running and foul plugs every ride.
just bought a 2024 xc 125 just because its fuel injected, if it wasn't for that i would have bought a 250 4 stroke
Most people don’t ride well enough to tell or need 98% of todays two strokes vs 80%. You and me included.
I'll never own a carb bike again. Immediate deal breaker. Also prefer oil injection vs premix but thats not a big deal.
Love my tpi
I’m pretty disappointed in my state CA for basically banning motorcycles from public land past 2023. I really wanted a new TBI bike, will need to keep this 2021 running for awhile
CA is a lib hellhole.
Can u premix an oil pump model xcw if you want?
My sons new 24 KTM 125xc fouled 8 plugs in 10 hours before he took it and had the “New Map Update”. We had no idea where to start. The dealers new map made the bike come alive. It was so bad it was sad.
Thanks for this thoughtful classroom. The probes are cool. Thanks so much.
What is the "new map"? Does that apply to 2023 XCs?
@@madsoothsayer apparently when they let him roll out the door the bike had an outdated MAP loaded. After several weeks of riding and changing plugs he was bummed out and even at the point of trading it in. He was told he was running the wrong oil and his mix was causing his plugs to foul. One of my riding buddies told me they intentionally have a rich MAP loaded so that during break in the engine has more oil. He was also told that he wasn’t warming up his bike correctly. After more plugs fouled we took the bike back to the dealership. The sales guy came back and said that everything should be good to go and that for some reason the MAP was never updated. Really? How come they charge you for set up and don’t set up the bike? This dealership is a great place and has sold umpteen bikes. Why is it just KTM’s that have this problem? I have never had a single issue with any of my 4 stroke bikes. I have literally ridden one of them for 13 years and never had to adjust valves. From the time I’ve been on his KTM I think it’s absolutely amazing. I want a 300 xcw but Dependability is a huge deal when you’re dropping $12-13 k on a bike. When you spent whatever he spent on his it should be actually race ready and not have problems like fouling plugs. I can see buying a bike in Californiastan then thinking you didn’t have to re jet for 12,000 feet in Colorado. KTM seems to have a big change from the TPI and TBI change. Hopefully they get it ironed out before I drop $13k.
