Top 10 KTM TPI Myths BUSTED | 2 Stroke Dirt Bikes
Вставка
- Опубліковано 29 чер 2024
- For the 2018 model year, KTM released the fuel and oil injected two strokes. It's called Transfer Port Injection (TPI). They were the first major manufacturer to produce this on a production dirt bike. With the 2022 models just around the corner, it marks 5 years of TPI bikes.
Ever since their inception, all sort of myths have flown around the internet, and many people have been scared to purchase this so called "un-proven" technology. Because I've owned nearly 15 of these bikes and ridden more than two dozen of them, it's time to help set the record straight.
Inside my small circle of riders, we've accumulated about 2000 engine hours on these bikes. Nearly everyday for the past 4-5 years I've answered questions in my email regarding these TPI bikes. These are the top 10 myths I've identified, given thousands of interactions with the viewers over these past five years.
Enjoy the video!

for the running oil in the gas myth, TPI stands for Transfer Port Injection which means it injects the fuel right before the air enters the cylinder. Running oil in the gas literally only lubricates the cylinder wall, it never even touches the the crank or rod bearings so it is a huge waste of time and can actually cause injector issues because they aren't designed to run oil through them.
I’m a simple man. I see TPI myths, I click.
haha!
Been following you for years. Your content improves every video. Thanks for the work. When I retire someday I wanna follow your lead
Excellent video neighbor! I added another horse 🐴 to my stable in February. A 21’ 250XC. It, along with my 19’ xcw have NEVER had a problem. They both run fantastic. I’m convinced those few people with problems have messed and tinkered with the fuel system: ie adding oil to the fuel, air screw too far out, etc. Some people can’t just start their bikes and ride them. They feel they must monkey 🐒 with things that don’t need touching. I love TPI and the thought of playing with a carb, makes me wanna 🤮
Great video Kyle! Lots of myths busted with this one, met a guy a year ago who had a 2020 150 xc-w tpi who had problems with it early on and he believed several myths you mentioned
Nice work buddy as usual ! Big thumbs up from Québec canada!!
Ya know some videos deserve a second like. Great vid bud
Hope everybody has an awesome day. Love the videos always.
Dirt bike chanel is awesome. Highly informative and recommended. Dispel those myths and give us the truth. I just bought a 2020 TX 300i and was about to drop $600. on a head and ecu flash. Thanks alot Kyle.
Thanks for the video! Great info!
Enjoy the channel and reviews, you are spot on with the myth busting, pulled my top end at 140 hrs piston looked good but rings were stuck on one side from carbon build up. I did adjust my power valve and enjoy the lower rpm power boost, great for my area tight woods single track N.W Wa. forest. 2018 300 WCW, Lectron carb, RK tech head, 16 oz clutch weight, Kreft suspension, Dunlop AT81EX rear tire. Keep those great reviews and tests coming
Kyle.... just a comment not related to the TPI you discuss here.
I believe you need to cover 1 significant aspect of riding which I have found to be critical to the sports safety, enjoyment, longevity and cost: it's the company you regularly ride with.
Riding mates have helped me no end in numerous ways from making sure I got home safe after a crash to saving me from making bad decisions on purchasing, on riding on the trail and maintenance.
They are the glue that has kept me there.
You might need a whole episode in this.
Cheers and thanks for the brilliant channel.
Great information, great composition, great editing, great production quality. You've really developed a great channel and I appreciate what you do. Thanks!
Thank you.
thanks mate another awesome vid . im still on my 2011 ktm 250exc , and enjoy it runs perfect for me . keen to see the 2022 models . cheers steve/Australia
I have heard several of this. Thanks for the knowledge
Totally agree with all the answers to the myths great high energy video👍👍
Thank you!
I wish I had enough time to ride 300 hours in a year
I would be happy to run mine at least 15 hours a year😂
@@cadwarrior think I just tipped 15 hours in the first year lol.
I do like 15 hours in a single weekend. You ride all day when you ride not just a run around the block. I don’t get how people use there bikes so little but spend so much for them 😂
@@jordanJohnn yup its weord how some guys ride like less than 50h/year and still change their bike every tear to a brand new one
Cool content man!
Thanks for this video!
Thanks Kyle, these myths have to be shown the door. I look forward to more setup on my 22 model
I do love me a good “dir” bike 😅 haha love the videos and keep up the great work 😄
haha! I was uploading that after 15 hours of editing! fixed it this morning after sleeping :)
Great video man and shoot for the stars. Can wait for the give aways.
Thank you.
💯 agreed great job Kyle! Thank you
Kyle you the man. Thanks for this
Support from Croatia. Love your channel very much. My 6 year old son is in motocross but hell man you are seriusly forcing me to get myself a bike and go to the wild.
Hey kyle just wondering if you have done videos on what gear you wear for enduro riding? Would be curious to know thanks!
Excellent video
I added a jd jetting power surge 6 which is an inexpensive way to add (or reduce) fuel at certain throttle positions. 2020 tx300. I do consider it worth it. Wanted more fuel to air to protect the motor a bit. I like the performance add as well, which for me is even more stall proof. Love the bike tho. Great piece by the way.
I've got a 2021 300xc-w tpi. Love it right out of the crate. I've been riding and racing for 48yrs. Hands down best bike I've ever owned. I've got about 25hrs on it now. Good video by the way.
Hi Dennis, how many hours do you have on your bike now? And how is it running. Just bought a 2022 with 5 hours and so far she’s been stellar.
They seem like great bikes. Cant wait to have my quad sold to hopefully afford a new 300 xc-w. Last bike I had was a 14 rmz250 and the last 2 smoker I had was an 86 trx250r.
Hey Kyle so I know you have already done a review on the ktm150xcw back in 2017 but I was wondering if you could do another review of it but compare that new 150 to the new te 150?
My 2020 blew up at 53 hours, just sayin! My theory, the oil pump didn’t like the cold weather (28 degrees) and it wasn’t equipped to pull the thicker oil at such temp. Yes, I used good oil 😉
You are not alone. We have had several seize prematurely in cold weather operation. The oil tank is not temperature controlled, and the recommended oil is thicker than snowmobile oil.
I just bought a used, 50h 250 tpi, first tpi in my life and after first 5min im freaking felt in love!!!
Appreciate knowing that. I have a 2022 300 XCW tpi ordered.
@@jeffcollins96 congratulations!
I sure like my 20 250xc-w with TSP high compression head ECU reflash kit. Best bang for the money. My bike did run good stock also.
Which head did you go with? Looks like a sick upgrade.
@@michaelschwab9563 High compression on my 250 and no regrets got about 30 hours on it so far.
I have 65 hard hours on mine and run Klotz it’s perfect. I did do the idle screw mod and open the power valve to my liking plus 48T sprocket
I love the idea of TPI on these bikes, however it would of been nice to see you actually bust these myths on camera, rather then just tell us your opinions based of what you’ve seen. Some dyno time would be nice 👍
I’m getting back into trail riding after 30 years , YIKES . Wondering if you have ever ridden a SWM rs 300r ? There’s a dealer close to me and the bike looks pretty nice .
So many TPI mods claim to “make it run like a carb’d bike”. That is all I need to know...it’s not time to upgrade my 2018 yet.
I own both... TPI is awesome. Carbs are awesome. Pros and cons.
On my fourth 300.... first tpi.. tpi is the best running bike I’ve had. Always added high comp head before... feel zero need to on this one at 4-10k feet elevation.
I’ve run lectron and smart carb previously. The off idle power on these is like a rekluse.
Lotta carb owners try to get their bikes to run like TPIs, just sayin'... :)
@@WASemiHardEnduro Makes sense to me as it does feel different. The first quarter throttle is less responsive/accelerates more slowly. However it's anti stall characteristics at 1/4 or less throttle is better not worse. You can clutch less.... and simply move from 0-1/3 throttle when in first gear gnar. This is why Kyle probably recommends the different throttle cam.... all you really would need to get more response at part throttle.... It took me a slight adjustment for me but the TPI is much better for gnar imo. Plus, its so easy to just ride and forget about oil, I fill up at the gas station alot now. I'm going to baja and I don't have to worry about carrying alot of oil, and can fill up whereever.
I believe KTM says 80 hours is the idea you're racing. And, if you've ever seen a pro race, we're nowhere near that, completely agree with you.
Hey Kyle, I am wondering what I need to do to help you out when I order a lectron carb? It’s for a 2002 CR250 2-stroke
Can’t wait to get my hands on a KTM 300 XC. Still riding my 2010 yz450f, thing is a monster
That bike is a dream!!! Baddest 2T on the planet
While everything you said in myth number 8 is true, I still think the older simpler bikes are more dependable, because I don't have a water hose or a fuse to go bad in the 1st place
As soon as a TPI can get over 300 hours on the same top end then I will buy one.
@@carlatamanczyk3891 That day is right now. I've seen it happen multiple times.
@@DirtBikeChannel Kyle, out of our group of 7 to 12 riders, the machines having some issues are the TPI motors and the bikes with air fork issues.
That is our experience thus far. And the 4 TPI bikes in our group are 2021 Husky (1) and 2021KTM (3) Just giving you what we are experiencing.
I appreciate and admire your 10 myths but I agree with the Dirt Magazine evaluation when they said that the TPI 2 stroke isn't ready for show time just yet.
I also see that for the 2022 models that TM is offering 2 strokes with the choice of TPI or carb.for the buyer.
For every 1 TPI bike they sell, 9 sold are carbed.
Anyway, really appreciate all you do.
@@carlatamanczyk3891 hey mate my hole family ride Ktm 3 out of 7 of them run 2021 Ktm 300 exc tpi with 340+ hours on one of them on the the top end also my buddy has a Ktm 2020 model with 315 hours on the same top end
you mentioned that these bikes don't need an aftermarket ecu to run well, and that if they run craps its due to something else.
i've read through countless forums with people experiencing the same issue as me...a random flat spot/bog in the mid range. seems to a very common complaint among tpi owners. like the bike is suddenly starved of fuel.
one guy had tried all the common things, fuel filters, sensors ect, had been in talks with KTM and his dealer, and even took his dealer to the track so he could ride the bike himself and experience the issue first hand.
after being told by KTM that is was just a "characteristic of the bike" he bought a Get ignition system and it cured the problem instantly.
you also put a Get ecu on your 300 a couple of years ago after it ran like crap.
i did about 230hrs hard shitty riding on my '18 tpi 250 before doing the piston, it still looked fine and only the rings were a bit worn. i did the oil pump at 250 because it failed and was 'leaking' when not being ridden and then fouling the plug on startup. have had other tpi owners in my circle that have had to replace the pump at 10-50hrs because of the same issue
You got a subscription from this video
This video made me feel like there is a ton of stuff I don't know or didn't grow up with understanding. I think I'll stick to the carb models for now.
Riding a 2016 husky. I think I'll upgrade to a 2018 or 2019 bike and look for a carb model.
Don’t bother with a carb. The TPIs are flawless when treated properly. They’re not as complicated as people make out. 95% of people just jump on and ride! All mine needed was idle screw mod (easy), air bypass screw adjustment (easy) and played around with the power valve screw (same as a carb bike) and it’s amazing!
@@Shoota211177 pretty much nailed it here. I spend a lot less time "tuning" my TPI bikes than I spend "tuning" my carb bikes.
@@DirtBikeChannel 100% agreed. I have owned countless bikes. My 2021 TE300i Husky was immediately my favorite bike I have ever owned and continues to be. Idle screw, tiny tweak on the power valve and it's a mountain goat.
How often do I need to check the air pressure in my forks on 2022 xc 300? Presently has 10 hors on it.
I agree, love my 2020 300 XCW TPI.. AND,,,,,, my 2 stroke snowmobiles have been fuel injected for decades and never had much trouble with those either.. ride what you like.....
All reasonable and fair
35 HARD hours on my '21 300 XC TPI - zero issues thus far.
What’s the exhaust smoke like, or is there hardly any?
Interested to know what single track trail you’re on during myth #3? Looks like Utah?
Would love to see a video about mindset. I have been comparing myself to others lately and beating myself up for not being faster/ better at biking. It is really spoiling my enjoyment of the bike, to the point where I've considered quitting.
I did a podcast on this topic with a gentleman - Episode 74 - dirtbikechannel.com/pages/podcast
@@DirtBikeChannel thank you, I will check that out
You just need to find some slower friends. 😉
@@adamclapham1153 👏
Aaaand...can you swap aux springs, or it is not good idea and you should keep the stock spring, but can tune it a little bit?
3:35 There's no way I'm replacing my piston every 2 days of riding. I'd just get a wr250r
Hi Kyle. Here all the way from South Africa. What would you say is the magic number for a new piston?? My bike has about 230 hours on and previous owner replace pistons every 60 hours. Now it’s time for renikasol and new piston? What is the magic number ?
2013 Ktm 300 xcw
Thanks
Which candle is better to put on ktm exe 300 2023 . Iridium or plain ?
What is the cost to redo the top end? Do you have to do it much sooner than a four stroke or is it about the same?
How do you think the TM 3n250es fi bikes (Italian version of a KTM tpi)?
Euro 4 emission requirements are also intended to make the motors tamper proof, even though the aftermarket has figured out ways around it.
If you can put it together. Somebody will be able to take it apart
What I find confusing is you have quite a few videos where you recommend the GET Ecu. What changed?
I'm old, like I've been riding over fifty years. I grew up on two strokes. I still have a 2000 WR200, which I still ride occasionally and love/hate lol. It never feels the same one day to the next, even to the point of one morning to the arvo. Are the new TPI's more consistent in their behaviour. I've been off dirties for a few years bar the odd run on the WR. I'm totally over riding on the road, here in Aus it's gotten crazy with the law and cameras. Even most track days are a shit fight now. So I've been thinking about a new dirty. I still love the two strokes and would be going that path on a new bike. The Husky 300 is winning so far. I keep thinking about the 350 and telling myself to go with my head and get the 350 4 banger. But my heart says I'll always regret not going the 300 TPI. Thoughts ?
I am about to buy a KTM 300 XC-W 2021. Do you think its worth it to wait until 2022's drop??
I want a TPI cause I want a low maintenance, low wrenching way to get into dirt biking. I want it to work like a 2 wheeled ATV for fun on easy trails around Sault Ste Marie, would a TPI be good for me then?
I may be looking for a ktm exc 300 2018.
This is fuel injecten.
Does these points also count for the 2018 the first tpi 300 from ktm?
Because it is the oldest of the bunch.
Hi Kyle, I was wondering what bike to buy to start out on for trail riding, I’m 14 years old, 5 10, and 140 pounds. My friend has a Honda CRF250F and loves it, I rode it and it felt great, but I was flat footed on it with my knees bent. Any suggestions?
Either the Husqvarna TE250/300i or KTM 250/300 XC-W are the best bikes out there for trails and enduro or general recreational riding. My sons friend who is 14 and a little shorter than you rides a CRF250F and hates it. He gets on my sons TE250i and just loves it. He also rode my TE300i and his dads 300 XC-W and is saving his money to get a TPI 2 stroke. The 250F is a generic trail bike that excels at nothing. After 30 minutes of riding you will out grow it and be bored out of your mind. Take the time to ride the 2 stoke slow and easy and learn how it reacts and feels. Work your way into it’s capabilities. It is a high performance dirt bike but can easily be ridden at every level.
Did your 2022 300 tpi come with a br7es spark plug ? Mine did and was just wondering.
Hey I think we live in the same state, where do you typically go riding?
gonna be a game changer when KTM and the other brands slap on e-start and tpi for the motocross versions. 85 with tpi pulling away from a race built 250?
You have lot of bikes🤩🤩can i have one of your old bikes 🤣❤️
I unfortunately bought one of these pieces of crap. 2022 KTM 300XC TPI.
The dealers cannot fix it and KTM will not cover anything under warranty even though it ran like shit from the 1st day.
I will never buy a KTM again.
I was warned I would regret it.
YZ for life
I bought a brand new 2017 KTM 200 and it's was a big lemon and just would not run properly. I just got a dud. However, I'd still buy another KTM as there's the odd dud in any dirt bike or machine .
The only person I trust with KTM's remaps the stock ECU on the TPI bikes for what they are used for, it is perfectly good as it is, but he finetunes the map for driving on the ice, sand, or light enduro, of course he doesn't give away his secrets, but absolutely everyone has been happy with his maps.
yeah! 🤘
I just bought a pro circuit platinum and a r304 for my xcw300 2022 i am alright with a stock ecu?
I think we need a four stroke myth busted video. Like 4 strokes are expensive to maintain. Rubbish! Trail riders like 95% of us are will almost never change a piston. Maybe over 500 hours we shim the valves twice and that costs 25 bucks. 4 strokes for ever......yeah I said it! Hahahah......but I love it if your having fun...that's all that matters.
New here just to confirm for 2stroke can use engine break when downhill.tnx
I strictly rode 4 strokes since i started 4 years ago. I bought a 250 tpi 4 days ago. Never riding a 4 stroke again!
Ha! Same boat. Never going back to 4 strokes EVER. We have a TE 300i and the 250. They are phenomenal bikes. Top of the food chain!
Looking at buying a second hand 2018 300 TPi, is this model worth the buy or should I stay away?
Seen a few issues online and wondering what my chances are of getting a lemon
Appreciate any help
I was hoping you'd say something about engine braking.
Wait do u have to replace parts of ur bike every few hours on all dirt bikes or just them ones
Yes when I'm racing I change all those things before manual says
which is the amount of oil consumed per 1 liter of gasoline? Or fuel to oil ratio?
On reliability...Readytoriderentals in AZ. Put 100 hrs on his 21 TPI with ZERO maintenance. ZERO!!! Not even an air filter. Blows my mind
For five years now tpi models, but why are ktm 2-stroke motocross models still on the carburetor? Power? Reliability? Can anyone tell if these tpi are so excellent ..
Can we have ten issue facts about those bikes too. Was there a tpi ktm that drove the bike backwards when in 1 gear 😄 or was that a 300 carbed version. Reverse gear ?
What kind of range are the 250 tpi getting on a stock tank? My 2021 xtrainer gets no more than 40 miles on a tank and that's with the smart carb.
Depends on riding conditions of course but I’m getting between 90-120 on my 300. For whatever reason my sons 250 get a little less.
Curious what bars you run and in what position
I back out my power valve from stock by like half a turn crank it in and watch out for that power band thats my favorite part of these bikes.
My 23 250 rips like a freight train, I have zero concerns about what ktm has done, I'll rebuild it at 500 hours and if it blows up before that then whatever so be it, awesome bikes
How do tpi bikes go after a drowning in a river just curious? Are they any worse than a carb setup ,
Pro tip. Don’t buy throttle cams from KTM unless you have a four stroke. They will sell you a set of 3 cams..1 cam for the 2t and 2 cams for the 4t. The 2t can is identical to what comes on your bike.... change the grips and throttle tube to a different brand if you want to shorten the throttle throw.
How is it on spark plugs? Do they foul plugs very often?
I bought my first dirt bike last year (2020 yz250fx) was looking through the manual and said replace the piston at 12hours. Got nervous I messed up buying this bike and did some research on some forums.. Nope dont change the piston at 12 hours
Thanks but I'll stick with my 19 300xc with JD keihin carb
My 17 carb Xcw beats my 21 300tx all day. But they are both great bikes. One day when the governments are overthrow I’ll come ride with you Kyle and show you worldly rider is the best, I’m just not a corporate sellout.
Not true about the ecu, Kyle. My bike did run like absolute crap until I got the ecu reflashed by tsp. Sure, a majority of them run fine, but not all of them.
but when would be the right time to change the oil pump, are there any signs? and if the oil pump breaks, will the engine crash?
Good question. I guess the only sign would be realizing quickly that your bike is running lean and shut er down. Great competition bikes but too many electronics to fail for my liking. I ride solo a lot and I'm not calling AAA for a tow 5 miles out into the rugged wilderness and I'd hate to leave a $12,000 bike out there while I walk home.
I start my 2021 ktm 300 cc tpi by accident all the time go to push the bike hand hits starter button it starts right up
if i buy anything from your store am i automatically entered into the drawing for one of the three bikes?
Anyone have a crappy running 2019 tpi because of ECU and installed a ktm 2020/2021 ECU into the 2019?
Hey, what trail at 7:12?? I am in Northern UT
