Jeff, thank you for the video. I have a '17 FE350 that I desmogged, Rocket exhaust and I put in an FX air boot with your Vortex ecu . Fit perfect, the temp sensor used different fasteners, but a really great upgrade and no snake oil used. Day/night difference!
Thanks alot for posting this Jeff. I have been reading some much stuff trying to figure out what to do. Really informative and appreciated.
Always learn a lot from your videos Jeff. You are always my go to guru for all things KTM and Husky. Thanks for making these videos and be well.
You're welcome.
I did this exact setup with my 2018 450 EXC-F a year or so ago and it ripped my arms off. The power difference is amazing and well worth the cost of the vortex.
I bought a leftover 17 husky fe350s back in March that the dealer had already done all of this to the bike for a guy & he backed out so I got a great deal !! Bike rips great video !!!
I just added the Vortex to my 450 six days. I had the EJK (JD) tuner on it prior , better than stock but still had flame outs quite often. Reeds are out as well . Vortex in -What a difference , this is the way the bike should come stock. Rode today on my tight single track and not one flame out - Big thumbs up . I also replaced the end cap
I have in 3 years now not stalled my 2019 KTM 500 EXC even once, my old Yamaha WR450 used to stall all the time... But on my bike all restrictions has been removed and ECU reprogrammed for the full 58hp. Fully uncorked KTM 500 is a tractor that have huge power from bottom of rpm and no matter what gear you have it in when twisting that throttle, and even more power at the top :) (it has surprised me more then a few times with power wheelies at 110km/h when I was passing slow cars just by twisting the throttle...)
Just did this to my 2019 six days what a difference no more flame outs why KTM would sell a bike that was trying to kill you I have know idea
Great post!!! Very helpful
So many junk products out there
Honesty and integrity are everything!!
Thank you for your kind words.
On my 2020 500EXC I removed the reeds and installed the Vortex and Pro Moto Billet end cap. Night and day difference!
did you add a computer to richen up the mixture? how does it run?
Glad to hear you do not need to put in the tube. 2017 350 exc-f brand new change the exhaust and took reads out. I set the TPS up on it but did not change out my ECU. From research that I did they said on the smaller bikes like the 350Z ECU was not needed and could make the change with just TPS. Bike runs incredibly well way more power. Does have the backfire on decel. But what I benefit by putting the vortec ECU in for the money.
I just installed the Vortex i purchased from you and removed the restrictions on my 2020 500 EXC. Wow, what a difference, well worth the $$$! Thing is an absolute beast.
Did u leave the emissions on or remove them I'm doing the same thing to my ktm 500 excf
Just installed vortex ECU and pulled the reeds on a 2019 KTM 250 EXC-F. Already had an SX exhaust on it. All I can say is WOW. Totally different bike now! Ripped around for a bit and an hour later I am still laughing and giggling like a kid!
@Keith Thurston you were able to put sxf header onto an exc-f
@@JustTip922I’m wondering the same
Thanks. Great info!!!!
Awesome video! So I have a 2020 FE 350 and it came with a 3 year warranty. I’m just wondering if I put the vortex ecu will it void my warranty? Or could I install the original ecu back on and not have the dealer know? And will the hour/ odometer still work?
Hi Jeff thanks for your video
I will buy the husqvarna fe 450 2021 I will eliminate the air box reeds. I think the fc 450 air box no longer has the reeds. I will put the complete fmf exhaust. I think we just need to put the vortex map because once we add more air we need to add more gasoline? are these 3 steps right?

great info there wow thank you Sir.....
My 2019 KTM 500 EXC did not have reeds in the air intake but a plastic funnel that was restricting air and it was a lot of work to remove it. Using reeds to do the same seems like expensive way to restrict the airflow... They did reprogram the ECU for full power (around 58hp) and disconnect the LAMBDA exhaust sensor at the dealership and for legal reasons I had to remove the air restriction and mesh in the exhaust myself. Top speed before removing air restriction was 110km/h as it was running extremely fuel rich :) After the top speed was around 175km/h.
Jeff, When I was cleaning my bike today I noticed the gasket on the reeds is half off just flopping around. Can I take it completely off without removing the reeds? The bike is de smoged -w- vortex & Pro Moto end cap. I haven't yet removed the reeds as I heard it will make the bike a bit violent on the low end and I' a bit hesitent. Thanks
Thanks Jeff
Thanks, Jeff, for being an intelligent, informed dirt bike guy. Your videos cut through the muck of CZcams content. Just a general understanding of the physical principles of engine and suspension function goes a long way in caring for and riding bikes well.
Love it!
Just installed a fastway end cap and removed the intake reeds on my 2020 KTM 350 EXC. It runs okay and doesn't backfire or anything, but it feels like my power curve isn't as smooth as it was stock. Feels like there are dead spots in certain rpms. Will the Vortex or GET ECU help with that, or am I just going crazy? I know the previous years it was more or less critical to install a new ECU when adding pipe or doing emissions delete stuff, but I know the 2020's are a bit different with the O2 sensor.
So I have a 2020 fe501 so all I have to do is take reeds out and punch the screen out of muffler and it will make a good difference with out a new ecu?
Love this video, thank you for doing it! So helpful. Any chance you know how to reset TPS points on a 2023 KTM 350 EXCF? It doesnt have a kill switch like yours but more of a traditional street bike kill switch that kills all connection to the ignition, so I am trying to figure out how to do the full open throttle point. Hope this makes sense. Thanks in advance!
Hello Dan:
Aim & Vortex will find the end points after a short engine run time. The GET ECU can be set with the app.
@@slaverace1 Appreciate this, thank you.
Could you please comment on the 2016 250xcf-w. Another great informational video! Thank you.
Sorry. That model is not popular where I live at high elevation so I'll probably never get my hands on one.
Do u have to get rid of the emissions if u put a fmf and a vortec and remove the reeds
Great info. Did you confirm that the SXF air boot is a direct replacement and good fit for the EXC?
You could just order the European market air boot for the exc without any restrictions.
SXF boot won't fit with the PDS shock. Need the euro boot.
The stock ECU MAP settings on my 2021 FE501 are fixed and won’t compensate for the lean condition the intake or exhaust will cause by improving air and exhaust flow. I’m doing the triple combo-Intake, FMF and Vortex next month all at the same time. The Vortex MAP has 10 preset tunes to choose from including altitude tunes. I can’t wait. I rode my buddy’s KTM with all the mods and I realized my Husky, while still a quiet torquey mountain goat, had asthma compared to his KTM.
Hello: Glad to hear you rode your friends bike for a little enlightenment. The combo of removing the reeds, updating to the Vortex slavensracing.com/shop/vortex-10-map-ecu-husqvarna-vortex/ and changing out the muffler to a Graves slavensracing.com/shop/titanium-diamond-muffler-by-graves-motorsports/ or FMF slavensracing.com/shop/factory-4-1-rct-titanium-slip-on-exhaust-husqvarna-fmf/ will totally transform your new scooter. Enjoy the ride!!!
Great video, Will setting the TPS end points work on 2020 ECW 300 as well ?
That procedure is for Vortex ECUs.
Thanks Jeff,!
I am hoping you and wife both heal up completely soon!
Great video, it is VERY much appreciated!
I have the 2018 EXC500F- I have totally desmogged it and changed the exhaust tip, plus I changed to the black throttle cam plate,. I felt huge improvements everywhere, it never flames out now plus has tons of torque, running 14-52 gearing for desert and woods trail riding.
I still have the "JD Tuner" piggyback device...
So, my question is about the Vortex ecm versus the JD Tuner device~ in your honest opinion does the Vortex make a huge difference over the JD piggyback tuner?
I am totally happy now but am wondering "how much happier I could be" 😊
by just swapping out for a new Vortex or the GETT ecm/ecu.
👍
MP
I'm a JD dealer and have known those guys for many years. They are good honest, helpful and knowledgeable people so I hate to say anything negative about their tuners.
All brands (there are several) of the piggyback tuners are made by the same company in Montana. I've tried them on 2 stroke and 4 stroke KTMs and have never been satisfied with the results. They help the fueling but don't go far enough and they don't make any changes to ignition timing or ignition advance curves like GET and Vortex ECUs.
If your bike runs well you might want to adhere to the old adage, "if it ain't broke, don't fix it" .
Jeff Slavens thank you Sir!
As always - good video Jeff. I know others have been working on a solution to connect the factory 2020 XCF-W KTM map switch to the Vortex and GET. Are you aware of this?
I will buy a husqvarna fe 450 2021
will eliminate a reed air box.
will buy the air box of the fc 450 i think no longer has reed values.
I will put the complete fmf exhaust. I think there is still a need to place the vortex map because once we introduce more air we need to add more gasoline?
are these 3 steps right?
Have to do anything else?
If I dont do this or put a vortex ecu on a stock 2020 ktm 500exc-f will I have issues with flameout? Can I ride a 500exc-f stock without flameout. I am sure the power of the bike is plenty for me I just dont want to have issues with the bike stalling.
On Vortex website they recommend running a FMF 4.1 with the ECU for the best power gains plus the ECU is mapped for the FMF and not the stock exhaust
Our maps are proprietary (not stock Vortex) and work well with FMF, XCF-W, Pro Moto Billet end caps and modified EXCF/FEs mufflers.
@@slaverace1can we run an sxf slip on as well?
Jeff, I just installed your Vortex ECU, wondering if you left the factory map switch connected. You mentioned one of the cables on the Vortex is for a map switch. Is one any better than the other. Can I remove it as I'm running out of real-estate on my bars? Thanks
I'm currently just using map 1 and no switches connected. I'll look and see if the OEM switch can be used by changing connectors.
So on the 22 fe501s can’t turn over with the kill switch flipped. Wonder how you’d set endpoints there
Followed you the whole way except the airbox. So do you just take the reeds our or try to outfit with a different airbox completely? Thanks and loving theses tutorials.
Sorry, sometimes I don't explain things well. The SXF air boot is just a possible option. Just remove the reed cage, remove the exhaust restrictor (if your bike has one), install a Vortex or GET and let er rip! It's a huge improvement with the same smooth power delivery as stock.
Jeff Slavens thanks and thank you again for doing all the homework and explaining this stuff to us. Be safe!
good video man. I just bought a 2020 ktm exc 500 with the O2 sensor. I'm having trouble finding if you need to install a fuel controller if you remove the reeds and put a more open end cap on the exhaust. New to EFI bikes. I always assumed O2 sensors was sort of a self tuner but when i did my first clearance check and pulled the plug, looks like the bike was running a tad on the lean side. I have seen guys on forums suggest its a closed loop system or something so the tuner would be needed. Bike does run good stock but you can tell its wanting to open up a bit more. Cheers!
Hello: Because KTM needs to be compliant with EU and US emissions standards, the programming only allows the ECU to make minor adjustments. I have an XCF-W that has different (richer) OEM mapping and I was able to remove the reed with no issue and my exhaust is stock, no restrictor. If you want your EXCF to run well, run cooler and last longer, buy the Vortex.
@@slaverace1 Ill get saving then. Thanks for reply
Did the 450 SXF air boot end up fitting? I've heard that the frame gets in the way on the EXC models but I wasn't 100% sure. Thanks!
It does not fit and not needed. Remove the reeds, add a Vortex or GET, mod or replace the muffler and let er rip!
Best Wishes Jeff, from Overseas...
Thank you.
Great vidya
I removed all the restrictions in the exhaust after that I messed with my idle and choke screws a little bit, my bike randomly backfired and shuts off while riding now I have no clue what’s going on but I think it’s the screws. Can you make a vid on adjusting the choke and idle screws
Did you ever do anything with adding fuel via programmer or ignition? If not your bike is running super lean
How do I calibrate the ECU if i installed an Athena GET ECU, instead of the vortex, on to a 2018 EXC-F 500? I don't have the wifi module.
Do you no longer offer that graphics kit? I really like it. I have a 2022 500 EXC-F
DH, I think we still have kits or can get you one quickly. Call in next week and ask for Alec. He is out of the office this week.
Should we modify the air box or side panel to open up for more air? There is a fin on side panel where air comes in that seems to block intake to airbox.
The mods in the video make it rip. I would leave the airbox alone.
Great info. Is the lambda sensor still used with the Vortex?
Yes.
@@slaverace1 I've heard the o2 sensor is not used by the Vortex. Now I see it is used by Vortex? I don't know what to believe. My 2020 FE350s currently has no lambda/o2 sensor. I'm not sure if it would be better if I did install the sensor, haven't tried it installed after the Vortex. My bike does currently run much better than stock. Current setup: no reeds, exhaust screen still intact, vortex set to all 5 and map 1, no o2 sensor.
@@kyl3dr
Sorry, I answered incorrectly. I called Vortex and the O2 sensor is not utilized.
You REALLY need to remove the butt plug.
Jeff, I have a 2021 KTM 500EXC-F. It runs really good for as plugged up as it is with lots of bottom end. I would like to just open up the EndCap or add the Fastway endcap/spark arrestor with no other changes. Can I get away with using the stock ECU or would that one change cause fuel mapping issues what will effect long term reliability? I'm not looking for more power, just better sound and a tad cooler running motor. Suggestion?
Michael: With the butt plug intact, no offense intended but your 500 runs more like a well tuned 350 so I highly recommend removing the restrictor plate in the muffler. I have a 500XCF-W and the stock ECU is different than yours that has leaner fueling. You will need the Vortex or GET if you modify or change the exhaust and you will be a happy camper. It will not rip your arms off or make make it difficult to ride. The added torque and HP will make it easier to lug the engine for improved traction and enjoyment. If you need more help, let me know.
@@slaverace1 in the video earlier you referred to the O2 sensor with compensate to a certain point would this not help by just pulling the butt plug out? Love you videos by the way
The sx-f boot will rub the shock since it’s for a linkage bike. The reeds actually improve torque. They’re only there to quiet that bike.
I'll install the boot to see if there is an interference issue.
The reeds do NOT improve torque, not even a little bit and I realize they are for noise reduction.
Jeff Slavens how much louder are we talking about and power without doing ECU change on 2020?
Jeff please let us know if the SX boot rubs when you fit it. Also do you mind specifying the part number? Thanks for the video and I hope you recover from your injury soon.
Thoughts on the JD Tuner? Will this work same as the others you recommend?
Never mind. I just saw your comments below about the JD tuners.
Where are you finding the air boxes. I’m having trouble finding one
I don't replace the air box or the boot.
Jeff , DiElectric grease on connectors ,yes or no.?
For this application, no.
So I was wondering if you new how to set the beginning of throttle and end of throttle on 2022 exc f 500. They don't Come with a kill switch just a on and off switch.
Did you ever figure this out? Having same problem
@Jeff Slavens I’ve done all these mods to my ‘17 Husky FE450. FMF Exhaust, FC450 (reedless) intake boot, Vortex ECU… my question is, what settings (MAP and Trim) on the Vortex box? Thanks!
Tom:
Most guys use map 1 but you can try other maps to see if you like them better. It's as simple as turning the clicker with a screw driver.
Before making trim screw adjustments, we need more information. Please give us a call and ask for Alec.
@@slaverace1 Thanks Jeff!
Jeff I wasn’t aware of the TPS reset after the Vortex, I have a couple hundred miles on mine but she’s running fine. Anything additional to do like unplug and reinstall the Vortex if I want to do the TPS reset now? thanks!
John In WV
John, just use the method in the video.
@@slaverace1 I have a 2019 500 EXC with a Vortex. I have always heard the TPS doesn't need adjusted. I guess I should at least try this method, seems as basic as it gets.
Thanks Jeff, in Europe we only have to remove the "removal CAT" and get rid of the cone inside the muffler.
Damn California! Altho i wish i could try a Vortex one day to see the difference with EU map
I have a eu model 250 exc f 2019. Are you saying that the intake is not like the us model ? Meaning it takes in more air? Thanks
ketchup sos yes there is no reed in the EU airbox
Cheers for that. What about the end screen cap on the muffler can I remove that without changing anything els ? Worth it ? Thanks
ketchup sos yes remove it. On the EU its even easier than the US because the screen is held by a nut. You can use the wrench that comes in your KTM tool bag (same nut size as you rear brake reservoir cap)
Oli M thanks brother 😘
Excf 250 six days 2022 .
Will i need the vortex/get/powercommander if i do the reed removal , butt plug removal ? Won’t the o2 sensor compensate for it as the bike is a smaller displacement ?
Do not remove the reeds or the butt plug without installing a Vortex, GET or Aim ECU. It will make it very lean and the Lambda sensor cannot compensate for that big of a change.
2022 KTM 500 XCF-W. Jeff, Do I need to remove the O2 sensor and block it off? I installed the Vortex ECU, added the FMF 4.1. Have not removed the intake reed valve yet either. Thanks once again for your expertise on these issues.
The Vortex does not utilize the o2 sensor. You can leave it or remove it.
@@slaverace1 thanks Jeff
@@slaverace1 Installed the Vortex ECU, FMF 4.1, and removed the intake reeds. Still experiencing flameout at low rpm. Any suggestions?

Hello:
Any mods to the intake or exhaust that increase air flow will require a different ECU.
@@slaverace1 tank you for your anwser 😊
What about for a 2015?
Can I do the same thing to my 17’ 500exc??
Thanks for your videos! So helfpul! On my 2021 500excf If I pull the reed from airbox and remove screen from exhaust I dont have to richen the fueling? bike will adjust on its own?
Hello: It will make a moderate compensation but not enough to make it run well. If you want it to rip, install a Vortex slavensracing.com/shop/vortex-10-map-ecu-ktm-vortex/ or GET ECU slavensracing.com/shop/get-rx1-evo-ecu-ktm/ .

Hi so if I remove the reed out of the air box or the screen out of the muffler on a ktm 350excf 2022 I have to get the ecu remapped?
Hello: The ECU can't be remapped. You will need a GET, Vortex or AIM ECU. slavensracing.com/?s=ecu&post_type=product
What about a 2008 530 EXC-R? Should the restrictor plate come out?
Yes. Those had a screw in type restrictor that can be easily removed.
Does this apply to a exc-f 250? The description does not include 250’s. Thanks for the video!
Yes
can I do this with a KTM 450 exc R from 2010? and what do I have to adjust? my exhaust often pops with flames
Hello:
Your bike did not come with reeds or a muffler restrictor. ECU companies do not offer anything for 2010 models. Take your bike to your KTM dealer and ask them to upload the latest map.
I understand the PC of calling out others but I am curious what Slavens considers snake oil?
Alleged performance products that do not improve performance and often degrade the performance.
@@slaverace1 I was looking for specific brands but understand if you don't want to put it out there.
Problem, 2021 500 EXCF does not have that style kill switch. It has an off/on switch in addition to start button and key. The only way the motor cranks is with the switch and key in the on position which will start it. Other positions do not allow the bike to crank.
Hello: Not sure exactly what you are talking about and I don't have time to review the video. If you are talking about setting up the ECU, the set-up procedure works on EXC-F models.
@@slaverace1 In the video you show holding the kill button,on the left side of the handlebar,then hitting the start button,on the right side of the handlebar,for about a second or so,the exc’s stock have a keyed ignition,and a stop/run switch,on the right handlebar only,there is no kill button on the left side.
My bike doesn’t doesn’t have a kill switch, it has a key. How will I go about setting up the TPS end points? It’s a 22 KTM 500 XCF-W
Plug and play. The ECU will learn the TPS end points.
Does the new ecu allow use of the stock map switch? How about traction control? Thanks in advance!
Yes and yes.
@@slaverace1 Is that hooked up to the stock xcf-w switch via supplied cables?
@@DoctorGoodnight
You're over thinking this. Just plug in the Vortex, set the TPS end points and ride it. There are no supplied cables. The OEM switch is plugged in to the OEM harness.
GREAT video and thank you for that! I have a 2021 KTM 350 EXC-F and want to do this. Can I do the same thing on the 2021 or are there differences in the model years that would prevent me from following these same steps? Thanks again for all your videos!
Hello, It all applies to your 350. We have ECUs here >>>> slavensracing.com/product-category/electrical/ignitionecu-components/
On the 21’ model will removing just the reeds do anything, saving up for a slip on
Removing the reeds will improve performance by increasing air flow but you must change the ECU to a GET or Vortex to add more fuel to match the air increase.
@@slaverace1 the O2 sensor won’t adjust for that?
do you have a similar video for the current generation?
This is the current generation. It's a 2020. 2020, 21, 22 are all the same bike with different graphics. Looks like the 2023 will also be the same.
Any reason going with the vortex compared to a Get.
Both units work very well. The GET has a lot more functionality with a lot of tuning options via the phone app but it's hard to beat the simplicity of the Vortex.
Have to do anything else?
I am looking at getting a 2013 KTM EXC-F it has a FMF Full exhaust system.
It has a piggyback tuner.
How much power can I expect out of one of these bikes ?
The new ones I hear are 55 horsepower unplugged.
But what about the older one The 2013 model ? I can't seem to find information on these bikes too easily
Hello:
Sorry, I'm not going down that rabbit hole. All unplugged, correctly tuned 500s have more HP than 99% of people can handle. If you think you're in that 1%, tape the throttle wide open and hang on. Let's see if you can ride it like a 125 pro rider. Please send the video!
If I remove the reeds on my 16 500 exc will stock ECU compensate
Sorry, no. You will need a GET, Vortex or AIM Taipan ECU. slavensracing.com/product-category/electrical/ignitionecu-components/page/2/
Is the Vortex tuner the best of the bunch?
The Vortex and GET offer very similar performance. The GET comes with a map switch and has many more tuning options.
Would this apply to the 2020 xc-f350 too?
The XCF models are not plugged up but one of our ECUs will make it rip!
Hey Jeff i have a 2020 350 exc-f in Australia. It came with no reeds in the airbox but still has a choked up exhaust. It came with the exhaust sensor but it wasn’t installed on the bike just came in the road package i was wondering if i removed the block in the end cap would i have to put the sensor in the exhaust? Cheers
I need to know this as well
Any answers on this guys??
Do you lose the stock Map 1&2 switching capabilities by doing these modifications?
With the Vortex ECU, the O.E.M. map switch and traction control still work.
@@slaverace1 Thanks Jeff for the reply. 2 more questions. I purchased the Vortex ECU from Slavens ( haven’t installed yet cuz she’s getting bigger springs for my fat ass). You stated that the stock map switch and TC will still be operable. Which maps will they use when the Vortex is installed? Next question,,, just purchased the O2 sensor block out kit from you. Is it mandatory ( or a good idea) to remove the O2 sensor with the Vortex ECU and FMF 4.1 and the intake reed removed?
Where do you get the map for the vortex pac ?
Our Vortex ECUs are preloaded with maps. slavensracing.com/?s=vortex&post_type=product
have u seen best dual sports power bundles ? do u use a exaughst manifold mod as well
that guy is a snake oil saleman. Probably the same $700 package jeff referred to
Yes, a snakeoil special.
Reducing the exhaust manifold diameter typically improves grunt at the very bottom of the powerband at the expense of reducing HP throughout the rest of the powerband. The trade-off is not worth the small gain for me.
@@slaverace1 ok thanks for heads up so his ecu are garbage ? only 200$
@@gonesleddinggonesledding6251
He does not sell ECUs. Those are just a piggyback system.
You might want to listen to Korndogger's comment above.
He has and some of what he sells works such as the exhaust manifold and the ECU tuner (same thing as everyone elses, he doesn't have some super profile). But he also sells snake oil with things like the fuel rail. Even under full throttle the stock fuel rail supplies plenty of fuel to the injector. It's hard to believe him when you know he's actively deceiving people
Did u see the snake oil guys video where he runs a tpi 300 on mixed gas with no oil in the oli tan and injectors in the stock location? He took the video down in 3 days lol.
Jeff, If I heard you correctly. Pulling the reeds is all that is needed if O2 sensor on exhaust? Does this apply to a 2021 500 XCF-W?
Hello: In the near future I'm going to re-install the OEM ECU and review how it works with the reeds removed. Please check back in 2-3 weeks.
@@slaverace1 Any updates on this? I have a '20 FE350 (non S offroad model) and wondering if I can yank the reeds and leave the exhaust/ECU for another day.
Jeff, did you ever try running with OE ECU, reeds pulled?
would a ktm 500 2021 run okay if reed remove and exhaust unplug no ecu or fuelprogrammer ? does the o2 sensor will compensate ? for it
IF you have an EXC-F, it will be too lean with those 2 mods and will require an ECU update. slavensracing.com/shop/vortex-10-map-ecu-ktm-vortex/ OR slavensracing.com/shop/get-rx1-evo-ecu-ktm/

You sell a device on your website (a snake oil product) such as an intake tube your speaking about. So why do you sell them if they are a snake oil product?
Hello: The one we sell from Mototerre is a bit different and gives a mild improvement. It has an internal twisted fin that directs the air correctly and increases velocity. We had many request for this type product so I found this one, tested it and put it on the site. It doesn't cure any issues and is not for everyone, but works well for guys looking for that last little bit of throttle response and HP.
@@slaverace1 ok thank you for clarifying. I was debuting taking my reeds out but I had no choice. The rubber seal blew off and the reeds were up against my filter. First time taking the filter off. Bike had 5 hours on it. So that ended that debut and there out. I bought a EJK, exhaust end cap and put a twin air power flow filter cage on and I’m not looking for any horse power. This bike you already have to hold the hell on lol. I just want the best running bike I can get. I had a 2019 Suzuki dr and that thing was rock solid. Never got hot, never stalled, never left me sit. And ran perfectly with idle set. I got the tuner and end cap to help reliably and the running not HP. if I could stay stock I would. But it runs like crap all bogged up. So would you suggest getting a intake tube if I have a EJK fuel tuner, reeds out, open exhaust end cap? Again I’m not looking for any power gains just smooth running.
At 12:11 you state that you don't need to stick a snake oil widget down the intake tube, so why do you sell a velocity tube for the intake? Maybe I missed something but the Vortex Intake Tube by Mototerre sounds like the same device you called snake oil that you hate people peddling.
Chad: Thanks for the comment. We handle several products from Mototerre and he asked us to sell his version of the intake tube which has a twisted internal wing that increases velocity and aims the fuel better. Also, customers kept asking for them so we brought them in. I don't use one in my 500.
@@slaverace1 Jeff, thanks for the reply. That makes a little more sense now why you sell them. I have one of those velocity stacks in my 501, and to be honest I did notice a slight and I mean slight difference in performance. Thanks again for the explanation and thanks for the videos and products, I have the air injection dongle you sell and it works great, so keep up the great work.
I bought the Best Duel Sport intake velocity tube and had to modify it to set flush into the intake boot. Did it help ? No clue but it's not hurting either.. it's staying in either way. Lol
Will this work on a 2016 xcf250w?
Your bike does not have reeds or a muffler screen but we do have ECUs. slavensracing.com/product-category/electrical/ignitionecu-components/
dose this apply to uk bikes?
Hello:
Sorry, don't know about UK spec bikes. We are in the USA.
Does the 2021 w have the o2 sensor?? Thanks.
Yes
Thanks. So by replacing the air filter box the o2 sensor should self regulate with the ecu? No adjustment needed to accommodate for the greater air flow? Then the second step would be to get a vortex and reset the parameters as you demonstrated.
I have a 2020 500 EXCF and I made these changes but I didn’t set the TPS. What difference will I notice if I now set the TPS. Also, if I put the stock ECU back in do I have to do the TPS setting again. Thank you. Great video by the 2ay
I have a 2020 fe501s and did not set the endpoints either. I thought you only had to do that with other year bikes.
@@Motorxkid1 I have a 19 500 EXC. I never did a reset with Vortex either. Trying it out today. I will try and report back any changes.
@@xnofriendsx I can't even do it with my bike since I have the fe501s
@@Motorxkid1 well for what it's worth I did that reset and it had zero effect. I thought my bike might be a bit off but it ran just the same. I thought the fe501 was similar to the 500 EXC. You can't do the reset? With a Vortex?
Did you notice any difference in between oem ecu and vortex? I just removed the restrictions on my 20 500excf but I still have the oem ecu on it
Any idea for a 2013 350 exc f? Performance mods ect?
Vortex ECU will make it rip.
I have a jd Power commander. Not sure if that’s similar? Or even If it’s good. I have it set to what they say makes it run better
What happens to that air box at 8000rpm
Works great up to 8000rpm BUT at 8100 it blows up and shoots you to the moon like a rocket. Ha!
Sombody know were the video are for removing the exhaust restrictor

When I de smog my exc can I plug off the vent hose off the gas tank or does that have to stay open ?
It has to stay open to prevent your gas tank from going into a vacuum and starving the bike of fuel.
@@ppod450 I just took the brass barb that was on throttle body and used that it still has a small hole to vent but won't allow gas to stream out in a tip over
@@michaelgreco5845 Good Idea, i will do the same, Thanks!
@@ppod450 don't know if you know already but that will break easy and there is thread locker on it twist it back and forth slowly until all the way out its a pain but it makes it easy to get out and doesn't snap off
These thing already rip. Unless you're on the competitive circuit these bikes have tons of power
Not everyone agrees and many want more HP.
What about 2021's ? ripe that stuff out ?
Yes
@@slaverace1 THX !!!
I thought I just bought a bike??? Am I gonna get a cel light!!🤣
Straight pipe FTW !!
