The REAL Way to Warm Up Your TPI - KTM / Husky / GAS GAS for 2023 [& 2022, 2021, ‘20, ‘19, ‘18]

[@rowieg2172]

Champion thanks . The bike shop sales reps didn’t really emphasise how long to warm it up for . There should be warning stickers on them new explaining all this . Thank Christ for KZbin and blokes like you

[@montanamtnmoto7927]

Have over 600hrs between a 2019 300tpi and a 2020 300tpi. Never have I fouled a plug and I live in a colder climate. Start it up with the cold start out leaving it idle for around 30 secs. Put the cold start back to normal and jump on and ride it it with around 1/4 throttle until it's warm. Good to go. Maybe thats what Kyle mentioned in his vid. No reason to over complicate. Maybe the 250s are a bit more touchy with fouling plugs.

[@WASemiHardEnduro]

Glad to hear you haven't had any issues! I believe by giving it any throttle while the engine is still cold, you're introducing MORE oil and fuel, which might increase your chances of fouling. Not every bike will have an issue though, so keep doing what works for you. There's definitely some variability with these TPIs - they all behave slightly differently.

[@MrFritz6940]

Same here. No issue

[@slintik]

Same procedure what local dealer mechanic told me... Id u re on track u can warm up 30-60s then shut down (keep dressing) and let spread heat across bike parts, then warm up again little bit and go slowly..

This is exactly what I do. Number one comment people make is "you're going to foul a plug" Its never happened.

[@imashankusobad]

I know right... and so what. I'd rather foul 100 plugs than need to do a top end sooner

[@-Just_Justin-]

This is what I do for almost every bike with the exception of older 2 stroke carbureted bikes. Tolerances are changing while bringing up to temp and when you wrap on the throttle it can cause piston slap,etc. I always recommend the factory owners manual or service manual over someone online. The manufacturer knows their product best. No engine was design to work in open loop efficiently, closed loop is what makes an engine operate where it should be. Adjustable fan settings can also cause issues with never reaching closed loop on occasion.

[@ShiftGearsMoto]

Dude, this was very detailed and informative. Thank you for setting it straight!

[@susumumori2553]

After fouling 6 plugs in 40 hours, I found this video. So far, your advise seems working. All you said in the video does make sense. Verdict is still out there, but if this really solves my issue, I can't appreciate you enough! I know there are many out there suffering from the same issue. Hope they will find this video soon.

[@WASemiHardEnduro]

Check your crankcase pressure sensor as well - if you’re fouling that much, it may be faulty.

[@danhopkinson2811]

one of the first thing i was told at a local mx shop when i started riding was always warm the bike up properly. you can actually cause a bike to seize starting it and riding immediately as the piston and cylinder will heat and expand at different rates. i've had this argument recently with some clubs and surprisingly a lot of riders who claim to have ridden for decades. i started racing timecard enduros and they don't let you start or warm your bike before you set off. you have to wait for your start minute then start and head straight out on your sighting lap. I was amazed how many riders from the club gave me abuse on the facebook page when i asked why we have to cold start. they said things like timecards are traditionally about testing a bikes reliability 😵‍💫 so in other words they believe the race is about intentionally doing something that could destroy your engine

[@WASemiHardEnduro]

Agreed on the cold-starts in enduros. I think it’s absolutely stupid. 99% of the riders are weekend warriors out there - why force them to put undue stress on their machines?

[@danhopkinson2811]

@WA semi-hard enduro. This was my argument, so these races are run by SEEC (south eastern enduro combined) which is a group of clubs in the south east of England that come together to run a timecard series and a hare n hounds series. Its only the timecard enduro’s you have to do a cold engine start. They allow you a longer time to complete that first lap saying it gives you time to warm your bike up. But warming up should not be done as you ride. They’ve had to cancel a few events this year due to low entries and that is most likely due to the fact that fuel here is around £1.75-1.90 per litre and things like tyres and oils have gone up around 30% in price. People can’t afford to race as often as events are on. It costs me around £260 to attend the race, so thats fuel in the van, fuel for the bike and my race entry fee. Thats not including any food or drinks on the day, or any breakages or parts i have to replace on the bike, nor general maintenance. They’re wondering why theres low entries when people are forced to do a cold start that could seize a bike and cost the rider £400-700 to fix ON TOP of what the day has already cost them. I think there needs to be some compromise, and race costs taken in to account if they expect people to continue supporting their clubs. However it seemed most of the riders were older and have been riding with those clubs for years and all jumped to their defence saying cold starts don’t harm engines 🙄

[@VFRCapBob]

Finally bought my first 2t in about 20 years. Took it for a desert race for my first time riding it. I knew i was in trouble the second I started it cold and began to play with the throttle and it died and wouldn't restart. I was such a clueless idiot. Now I have some good info. Thanks

I still ride it when it over heats and boils over...idk dont really care and had 0 issues with my tpi. believe it or not still has the same ol spark plug. changed the piston at 150 hours thing barely had any wear and cylinder looked fine. im wondering if you can even foul these dam things. I had to use my buddies pre mixed gas for his old YZ250 since I ran out of gas didnt even foul. I rent mine out to people also and I know they dont take care of it and still everything works as it should.

[@CrashNBurnOutdoors]

MY 2021 HUSQVARNA TE250I HAS NOW SEIZED 3 TIMES WITH ONLY 11 HOURS AND 48 MINUTES OF RUN TIME. Was told it was my fault and out of warranty(bought in Nov. - First seized in late Feb.) anyway so I had to pay full price. Didn't argue, but then after only a short ride or two, the bike started to run rough. Let it warm up for a very long time(10-15 minutes) rode down the trail 2 miles and the bike stalled out and seized. Couldn't start it so I had to push it home. Second dealership said they fixed it, but could not really give me a straight up answer to what was actually wrong. After getting back from them I rode it down the trail this time making it only 5 miles and the engine seized again causing me to almost crash. All along the way I was told these dealerships were reaching out to Husqvarna/KTM about it and once I finally got a call back from customer service after at least 3 voicemails and multiple email submissions the lady told me they had no record of cases on my VIN. The final dealership reached out and came back to say that KTM will not do anything to help and said it was all my fault. I am a degreed Engineer, have been riding for 17 years, and own 5 other bikes... so I know how to take care of them. NO YAMAHA, KAWASAKI, HONDA, TRIUMPH, SUZUKI, ARCTIC CAT OR SKIDOO THAT I HAVE OWNED/RODE HAS EVER FAILED THIS HARD, THIS CONSISTANTLY AND THE MANUFACTURER JUST TRY TO BLAME ME.

[@WASemiHardEnduro]

Wow that sucks. There must be something really wrong. A good mechanic should be able to diagnose why it seized, or at the very least point to a potential cause (cold seize, lack of oil, foreign matter, other?, etc).

[@unclegeek]

Sweet thanks, this is what I have been doing but now understand why

[@human1513]

Not sure why I get so excited on thsi subject. Maybe it is because it took KTM 11 months to fix my bike. Many but not all TPI's (~10% to 20% of all bikes) require the air Bypass screw to be adjusted. KTM labels it as an idle screw which it is not! My 2022's partial throttle vastly inproved to acceptable by turning it from stock 3.5 turns out to 2.0 turns out (in which is richening it). This helps warm up,.. and partial throttle openings. Every year of TPI came from the factory with the air bypass screw set at a different # of turns out. KTM N. America head of sales says they cannot tell the public but to get the tpi bikes to run properly they must get an after market software map, typically done via an after market ECU (I heard this from a senior bike tester at a major bike site but cannot find the video presently). I know the TwoStrokePerformance (who reflashes the stock ECU), Coober ECU from Austria and GETS ECU (which is also programmable) are 3 rather popular ones that do wonders for the bikes. A compression head from them also 100% improves everything. KTM put a brand new 300 CX TPI crate motor and oil pump in my 2022 after the original ran like crap from day 1 then seized 2 times @ 7.20 & 7.4 hours. KTM and the biggest KTM dealer in Canada told me to not warm it up at idle more than the time it takes me to put my goggles on! It now runs perfectly following their instructions (which I also followed once they told me this with the original motor. Actually they practically yelled at me to do it thier way. The way their staff riders and racers also do it). This does not mean put it into gear and scream it until it is warmer. It takes less than 60 seconds for it to get running very good once starting to ride it. Unles it is neear freezing temps out side. I now also have a rad temperature gauge (Trail Tech) also so I know the temps it is at. Warm it up while riding it is the best way. Just like cars now will never warm up idling them. Circulate the oil then start driving gently. I am a licenced mechanic and Cerified Engineering Tech, Electromics,.....not some KZbinr with his "I think this it the way.."

I have a '21 TE 300. In the owners manual on page 40 under riding instructions it says " Switch off the engine if running at idle speed or stationary for a long time. Guideline greater than or equal to 2 minutes" Kyle's advice is to ride the bike slowly to warm it up. He isn't saying to go bounce it off the rev limiter.

[@WASemiHardEnduro]

That’s right - I wouldn’t recommend you let the bike idle for extended periods *once it’s warm*. The manual doesn’t mention a warm up procedure though. Kyle’s advice puts you at an increased risk of fouling a plug, due to the way the TPI works. No, it won’t always foul a plug - some ppl will never foul a plug following his advice. It doesn’t make it good advice for everyone though. I’m just presenting information and a dissenting opinion, and people can decide for themselves.

[@evanwilliams6352]

Engines are not designed to run cold, so you should try to warm up your bike sooner rather than later. (This is one of the reasons cars use thermostats, they stay closed during warm up to help warm the engine quicker) Running a cold engine for an extended period of time can actually cause ring and scoring damage, improper lubrication of parts, etc. If it takes 10 mins to warm up a bike that’s about 4-5 mins longer than it should take. That’s 4-5 minutes of premature wear that you can cause to the internals of an engine. I’d take a fouled plug over premature wear any day. So I’d try to warm it up faster than what you’ve mentioned in this video. Now that being said, you can also cause even more damage by warming up an engine too quickly, so you need to find a good middle ground. This goes for any engine, weather it be a 2 stroke, 4 stroke, Wankle. I’d say that Kyle actually has a pretty good technique for warming up a bike, IMO. But to each their own, you do what feels right to you, in the end, most techniques are only going to change the outcome by such marginal amounts, that it really doesn’t make any difference.

Man these TPI bikes give me a headache, I just bought a new 21 300xc TPI and within the first half hour on the hour meter the bike locked up and destroyed the whole engine, dealer took it back and it turns out the head was machined in-properly at the factory and when it heated up it warped and allowed coolant to seep in and effectively destroyed the engine. I'll most likely get the bike back in April of 2021, on another hand I think people put way to much thought into this. The way I would warm up a TPI is the same as any 2 stroke, Just put your gear on. Start it with the air by pass knob and let it idle for a minute or two, turn the knob off and slowly go. Don't rip it through it's gears but lightly start riding the bike. EFI or carb the engine will load up and it's just generally not the best for a 2 cycle engine to come up to temp simply by idling it. A carb 2 stroke is a little different where I'd be less likely to have it warming up on it's idle, I'd blow it out while it's idling. just ride your bikes guys!

Do I need to let the bike Idle without the cold start button until it reaches 135 degrees ? Would it be likely to foul a spark plug letting it idle for too long ? Thank you and keep posting this kind of videos.

[@WASemiHardEnduro]

The TPI should be able to idle fine without fouling a plug. I still let mine warm up to about 130+ (on the radiator gauge) regardless of ambient temp.

[@chrisbirdsong1112]

Do you have a video on how to properly start up the bike going from low elevation to high. I'm leaving from Georgia and going to Colorado in a week for the 1st time on my 2022 te300i. I know my 501 is a simple start, stop, wait then start again. The book says the same for the 300i but I've heard of people having issues in high altitudes with the 2 stroke tpi. Thanks in advance!

[@WASemiHardEnduro]

It should adjust on the fly since it has an ambient pressure sensor. Only the 18-19 TPIs required a restart at elevation. But if you have any weird running issues, a quick stop/restart should be all it needs.

[@riders.oregon4474]

This is the same way I warm up my TPI . If it is 45 f or below outside I will also duct tape over the the right side radiator for moderate and high speed riding.

Great video. So in the summer, the ambient temp may be 80-90 degrees Fahrenheit but the engine could be pretty cold ( cold garage).... would you still use cold start button and let it idle until around 150 degrees or use cold start button for a for a little less? I followed your video when I got 250 xcw tpi home in 35 degrees on 3 different days and it worked great. Just curious about warmer days. Thanks again!

[@WASemiHardEnduro]

I don’t use it unless the ambient is 50 or less, so in that case if the garage is over 50, I wouldn’t use it.

[@AbBc-w4q]

my 2021 TE150i is spongy as hell until the ecu determines it has warmed up and there really is ZERO point if even trying to ride it. And Im pretty sure trying to ride a cold piston in a cold cylinder on a 2 stroke is a good way to accelerate wear. MY problem now is I let the bike sit for 1 and a half years in the garage and now it wont start. It turns over but seems like its not getting fuel if I had to guess. I'm wondering if fuel sitting in an injector gums them up if not used. Only thing I can think of since all it did was sit there.

[@WASemiHardEnduro]

You'll probably have to go through the whole fuel system after letting it sit that long. Could be anything from the pump to filters to injectors.

[@gonyg5316]

Also forgot to mention that it needs to have the latest extreme enduro map uploaded and the standard plug fitted. One dealer tried to tell me that the tpi models are going back to iridium plugs but this is rubbish. They run like a bucket of shit and it costs you $38 Australian to find this out and then the dealer says oh well that’s what KTM recommend.

[@hermitrob5481]

Slavens says its not a cold start button, but a fast idle button. Says it has nothing to with adding oil, but it adds air. Basically refutes everything you say. Not sure what to think. If thats what the manual says it is that must be what it is.

[@WASemiHardEnduro]

The manual calls it cold start, but physically it’s just an air bypass. The ecu adds more oil during startup regardless of cold start position. You don’t *need* to use it, but it definitely helps when the bike is cold, and can help prevent fouling. Also Slavens is an idiot who deletes any comments that disagree with him. Feel free to disagree and debate here though. 👍

@@WASemiHardEnduro Omg he’s the grouchiest MF on the internet. Bad wording sorry. Wasn’t doubting you. Just got the thing use it every time so far.

[@WASemiHardEnduro]

@@hermitrob5481 👍 They’re pretty solid bikes as long as you warm them up before getting on it hard. Keep the air filter clean, change the gear oil, and don’t drown it. :) I have 260 hours on mine, did the top end recently. I’ve had to replace some CCPS sensors - that’s the only thing to really watch for. If it seems to be running rich down low/stuttering more, just replace the CCPS.

[@beauclose2235]

I let mine idle for about 20 seconds then rev it about double idle for 60 seconds seconds without riding it then ride off I do lots of desert so I don't foul plugs I just don't have the patience to wait 10 minutes for it to warm up

[@SteveKiziak]

Do you recommend tapping up part of the rad when ambient temp is below 5-10c? That temp is what we have (on average) 6-months out of the year in Vancouver B.C It seems engine temp can vary greatly depending on how fast you’re going.

[@WASemiHardEnduro]

I’m in about the same region. I haven’t seen the need to tape up a radiator yet, riding at those temps, but it probably wouldn’t hurt if your speeds are a little faster. Maybe if it was below freezing, I’d try it.

[@joshpodolsky7740]

Don't worry about that unless you are actually riding in snow. I know snowbike riders will cover up both rads if they are gonna plow into some powder. But cruising down ghe trails they will uncover the rads cause it will actually run hotter just going down a trail.

[@lambrosmaouris4092]

[@scannorse]

What would be the procedure on a carb bike, and how to avoid fouling spark plugs ?

[@WASemiHardEnduro]

Really depends on how the carb is tuned. Generally don’t want to let carbed two stroke idle for very long at all though.

[@kirkwilliams4942]

First thing... get ride of TPI injectors and relocate them where they should be. At the reed block.

[@user-qx1zt8mq4q]

Ok so i just picked up my 2022 Husky te 250i. Got it home and put some bling on it and then decided to start it. Umm i used the cold start nob but ever so often the motor has a knock that resonates threw the bike ! This can't be normal .

Carb bikes are just so much better than these new tpi bikes. Ill stay with my carbureted ktm for a lot longer. With a 4 stroke fuel injection is great but this tpi still needs a lot more work.

[@WASemiHardEnduro]

TPI has some strange variability for sure, but people are starting to really figure them out. I’ll never go back to carbs.

[@kimojon9665]

It's the internet, not the TPI. These systems are amazing and work solid. I will never go back to carb bikes. The response and lugging on these TPI's are just outstanding. When you look at the complete system it's super simple. The internet has to make everything much more difficult than in real world.

[@keef902]

Hmmmm. Weird I only fouled plugs when I followed this type pf procedure in my first 40hours....now that I dont let it idle long and just go for an easy ride to start....no fouled plugs. Thanks for the mis information though!!

[@stillcantride7159]

What bike?

[@keef902]

2019 ktm 250 xcw tpi 💪🙏

[@rusty78364]

I was gonna say the same thing. tpi or not, a 2 stroke functions the same. Oil is mixed with fuel in the combustion chamber one way or another. and the combustion point of oil does not change so letting the engine just sit an idle and come up to temperature wont change the fact that oil still needs to combust at a certain temp. Im not saying start it up and go rip but definitly dont let it sit and idle for 10 minutes... or else there will be unburnt oil regardless of how lean the bike tunes it.

[@chrisboon4526]

Thank you for this video, that was very informative and easy to understand. I plan on buying a TPI dirt bike in 2021 (hopefully).

[@louisdriscoll8084]

It’s funny how some of the riders in park think up doing it all wrong

[@gonyg5316]

It’s simple. Let the bastard idle with the choke out for at least 5 mins. Otherwise get the spark plug spanner out. I always wait until the right hand side radiator starts getting some heat into it. This does however vary a little if you are running the thermostat eliminator hose kit.

[@WASemiHardEnduro]

I highly recommend NOT deleting the t-stat on these bikes. They’re cold blooded enough.

[@charlesswiger2260]

Do you do the same warm up on the 2023 tbi husqvarna tx300?

[@WASemiHardEnduro]

It's a different system on the new TBI bikes. It's still important to fully warm up your engine before getting on it hard, but the new TBIs may not like sitting and idling for too long.

[@fullblownMS3]

I must be doing something really wrong. All my life I have let everything warm up before I ride it, but my 20 XC loves to foul plugs if I let it idle to warm up. I even switched to iridium plugs which seemed to muscle through the oil a little bit better but are not impervious to fouling.

[@WASemiHardEnduro]

1. Try using the cold start for a bit first - sometimes extra oil can seep into the TB when bike has been sitting - cold start will help it burn. 2. You could have a bad CCPS which is causing the bit to run a bit rich.

[@fullblownMS3]

Why is this so hard for people? If its cold and the bike wont start, use the choke. Remember if you have changed elevation the TPI system needs time to alter the air/fuel mix. Once its started if its idling way too high just close the choke. Leave to idle for 5 mins. Ride.

[@jswervy16]

So my buddy deleted his thermostat. I can't help but feel he stifling the warmup process and possible heading toward cold siezure situations. With coolant flowing from startup, the piston and cylinder dont warm together. Thoughts?

[@WASemiHardEnduro]

Yeah, I'm not sure deleting the thermostat on these bikes is a good idea. I don't see any benefit, and the TPIs are cold blooded enough already.

[@rayrayray4116]
