KTM TBI FUEL INJECTED 2-STROKE PROBLEMS TO BE AWARE OF

[@defconsupply3990]

[@goinhot9133]

Well this is a bummer, however expected with all the new crap.. I have a restored ‘07 250sx.. there’s like 3 wires on the whole bike lol carbs are easy, sure you can’t get the most performance out of them but it’s fractions of percentages anyway. My model carb bike comes with more HP according to KTM. The new stuff is so complicated & requires so many systems..

[@moto-x]

The carbed bikes are more reliable right now and similar or better performance. The efi bikes are smoother less of a hit but that is all manageable with a carb bike with the power valve adjuster and gearing. Stick with the carb bike, in a few years everyone will be seeking them.

[@moto-x]

Lol, you’re dealer won’t cover it, mainly because they can’t figure it out. KTM can’t figure these out and if your past your first piston change in hours you won’t even have a shot. Glad your bike is good. These aren’t isolated incidents, there’s more then a few of these bikes having issues. Additionally when you have to buy tps tools, diagnose electronics, reseal ccps, and try to fix your new bike that’s a poor customer experience. This isn’t 1979 where all bikes were not reliable. Shame on KTM for putting out unproven technology.

[@JasonTylerS]

@@moto-x everything you’re saying makes no sense. First of all I still have my dad’s 1979 Yamaha YZ250 and it’s very reliable. You say there’s more than a few but they’re not isolated.

[@craigwicke4835]

When you start any engine let it warm up and ride easy for 2 or three minutes. Don't redline it with no load. This stretches the clearance out of rod and stretches the rod. If the squish clearance is a little small it might let the piston hit the head. Increase your premix oil. You can try 32:1. Maxima 927 or your favorite high rpm premix. More oil may need a richer fuel mixture. There should be a procedure to richer up the TBI. Just clean the spooge off the silencer. It means you are getting plenty of oil.50:1 ratio premix has more additives in it to make up for less base oil. More oil gets up the bottom of piston to lube and cool it. My 2 cents.

[@moto-x]

Thanks for the advice, been around the block a time or two with two strokes. Aside from all the normal things we knowledgeable two stroke folks do, these bikes have issues. The bike was already warmed up, it’s illustrating the surging while holding the throttle steady. These issues are well beyond basic two stroke warm up and premix.

I can't recommend this bike based on my experience and two close friends, plus the countless others. I would give these bikes a few more years. There are many known issues and many unresolved issues that you simply can not fix, nor can the dealer. Buy a carbed two-stroke or wait until these get sorted out.

[@onthethrottle7104]

KTM sells thousands of these bikes each year - some guys run them in ways they are not built for so you're going to see some crazy photos and videos. So if this is such a major issue across the board like you're saying, where are all the posts on the internet? Now days if your new bike doesn't hold up owners plaster the complaint all over the internet. I don't see the problem you show...happening. Also, all bikes have their issues and you can find every type of bike with blown engines. I guess we'll need to come back to your post here in a few months and see if there are just tons of people posting about this issue or if this is just another one man internet story with a few people that got unlucky and that will join your story.

[@wernerxldata]

Without disrespect to the problems you have a few remarks and questions. There is always a change stuff breaks, you can have bad luck or a production failure in parts. It happens with every brand, model, car or bike. I worked at a Mercedes dealership where a customer got his new C220 CDI, normally an engine good for at least 500.000km, the guy called half an hour later, engine was exit. It happens. I'm curious about statistics of these failures, where do they come from, it's quite normal people with complaints (right or not) post videos or messages on forums, while satisfied owners usually don't. So I'm really interested in seeing how many bikes fail if it's really a deviation to other bikes. It's new tech so it attracts attention. It's easy to have conclusion but is it true. By the way, some of the broken pistons look like detonation failures. For me one of the reasons not to buy a 300SX yet, can't change the mapping. I'm lucky to have pretty good fuel here for a decent price, that helps but not being able to change mapping is a problem in my opinion. The 2025 model seems to get an ecu / app where you can, at least the 2024.5 fourstroke models have this option. My experience in 12 years of ktm's, containing 125's, 150's, 250, 250f, 350f, 450f is they all run a bit too lean for my conditions stock. The past few years they also closed the fourstroke ecu's, so we were forced to run GET or Carrot ecu's, not fun in means of costs. Anyway, it really sucks if you have a fairly new bike and it still breaks, not really used to that anymore, in the 90's it was more normal. Hope it will be fixed for you so you can enjoy the bike again.

[@moto-x]

Thank you. Unfortunately there was nothing they could do, not KTM, not anyone. So you either have a bike that runs terrible randomly and don't ride or you move on. It's disappointing because I have had three other KTM's and they have been great, but these new TBI's need some time. Nonetheless, KTM should not have put these out to the masses yet.

[@wernerxldata]

@@moto-x You're right, this needed more testing in more different situations. KTM moves forward quite quickly, and while that creates innovation I've got the feeling it's sometimes a bit too quick. In the end it's really people paying their real hard earned money for these bikes. It's really shitty if you pay a lot for a bike and you can't ride it. Hope this works out for you.

​​@@moto-xAll single track. The others in the riding group. Have 23 XC 250's and 300's. All hitting well over 100 hours before a first rebuild. I guess we were lucky....ha,ha. Love my 300 and wouldn't trade it for any other bike on the market. It's a ripper in the woods

I’ll add to the list make better maps and measurement systems for 2t these behave awful.

[@Pinionaire]

Throttle Body injection has nothing to do with this, in fact the relocation of one of the injectors into the throttle body allows for a better combustion of the oil air mix, which increases reliability. Now I'm not sure if I'm judging to quick, but that warm up procedure you filmed was quite abusive... CRINGE If that bike wasn't properly warmed up. Let it get up to temperature and ride it gently going through all the gears before wailing on the throttle.

[@moto-x]

That wasn’t a warm up, bike had already been running and was up to temp, that was to illustrate a steady throttle and what the bike does. The reference is between TBI and carb as you can hear in the video.

[@zydecbro]

someone should come out with a carb conversion kit for the tpi bikes

Tbi runs at 6volts alot of people have bad batteries and cuase half these issues

Have you ever actually checked internal clearances or are you just repeating what you’ve read online?

[@moto-x]

Yes we’ve checked clearances. Have you?

[@path5362]

Sure have. On stock and Wossner. What did you find as the closest area and how close is it. Would help to compare multiple setups. I have pictures as well

[@path5362]

That’s the same thing that I found, and that’s not going to cause contact. So now the question is what is really happening. Did KTM accidentally put some of the longer skirt pistons in from the factory? Something to think about.

If a piston is contacting the crank it’s ALWAYS going to contact the crank. Not only that. If a piston contacts a crank the engine isn’t even going to spin over. It will lock up in place it wouldn’t even run. Revs have nothing to do with it. Ktm doesn’t use such a cheap rod that it stretches….. so that being the case you might want to rethink your mechanical analysis of this. Bogging? Check your fuel. Bikes with injectors especially ones you put oil through can clog easily. Especially if you run castor as it changes consistency a lot with temps. Still Bogging? sounds like a lean condition these bikes are known to have. Run good fuel. Haven’t had any issues yet with any of the ones that have been through my shop. Doesn’t mean there won’t be but there’s been 0 of the issues your reporting on.

[@moto-x]

Not true at all… Production tolerances, some made it through, some didn't, some riders are slower and don't rev it hard and some do, causing it to smack the crank halves. Look it up it’s a known issue hence why the manufacturers are making different pistons…The bogging isn’t one or two guys having the issue, there’s a ton of them that do this regardless of the fuel or oil used. The issue isn’t just bogging, they cut out, load up and there’s a number of mechanical items that can cause them. Go look at how many low hour TBIs are for sale for dirt cheap, there’s a reason…skirt smacks crank, cracks skirt, pieces break off, wedged around the motor, motor locks up, want to keep running, cranks snap, etc.

[@user-mo8tm4jw2l]

@@moto-x regardless of production tolerances your trying to tell me an engine can spin through metal on metal contact. Factually It cannot. Engines like that wouldn’t leave the factory. If you want to tell me there’s a faulty casting I could believe it and believe a piston to crack or break. It happens. However for you to claim the piston skirt is contacting the crank and the engine can turn over properly is pure and simply impossible sir. It would be noticed during assembly.

[@krazed0451]

@@user-mo8tm4jw2l Did you listen or read at all? It's only occurring at high RPM, you're not gonna notice it turning the engine over during assembly.

[@user-mo8tm4jw2l]

@@krazed0451 yep. Sure did. this is kindergarten level engine building for ya bud. If it doesn’t contact the crank when you rotate by hand it won’t contact the crank at rpm. Speed of rider doesn’t have anything to do with a piston skirt contacting a crank. You’d have to use a spaghetti noodle for a rod. This isn’t rocket science. 😂😂😂😂😂😂

[@krazed0451]

@@user-mo8tm4jw2l No, it's a 2 stroke engine. I'm aware of how they operate, if you think the additional forces and heat expansion involved at high RPM don't close up tolerances at all you're detached from the real world. Your cute little supposition that a piston can't rotate past the crank if there is any contact at all is laughable, too. Have you ever built an engine of any kind? I've built one or 2 over the years... I'm guessing you stopped at kindergarten engine building.

I love watching these video essays about how their KTM's blew up because they ride with no discretion and blame KTM for it. Stop gaslighting people with your outlier issues that 99 percent of people don't have.

[@moto-x]

@drpork1360 alright I’ll be blunt pork boy, Maybe you’re a ktm fanboy or something but the reality is these new TBI bikes have issues, those are facts. Your claim is like most people who don’t like the truth, unsubstantiated. Do you have hundreds of real world examples of how great these new bikes are first hand? Didn’t think so…

[@drpork1360]

​@moto-x No, YOU had issues with YOUR bike. I own a KTM, and I've had no issues with it. Instead of making a video complaining, you should've brought it to KTM or talked to your dealer and ask them to expedite your issues and message to KTM. Also I'm a fanboy of any bike I own, I happen to own a KTM so I like them and will stand by them but when there's real issues to talk about I will talk about them. But your issue sounds like a warranty dispute. My dad for example had a leaky fork seal after 20 hours and the warranty took care of it. You could've done the same but you went on youtube and complained about it first to get some hits and to piss some people off who know better. 😂
