My model carb bike comes with more HP according to KTM. The new stuff is so complicated & requires so many systems..
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.

The biggest problem with today's engines is the high emissions requirements, which means they get too little fuel, which makes them much hotter because fuel also cools the engine.
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.
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 have had a pre 2017 xcw 300 and a xc 250 that were fairly trouble free. After watching this video I will buy a Rieju 300 for my next bike. KYB suspension, carburetor, kickstart and premix works for me. Plus you get a two year warranty.
Also, the endless electronics, sensors like I want to ride not chase down electrical diagnosing for hours on end - oh part is backordered out in the ocean for a year.
I have a 2024 Husqy TE300 and it’s the best dirt bike ever IMO. If this issue does happen for some crazy reason then my dealer will handle it. Came from a carbureted bike and there’s just no comparison especially riding at high elevations above 13,000 feet in Colorado.
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.
@@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.

Hello i live in ivory coast and My friend got the sx 250 2023 all new last year. The first day the bike started to bug ! He has tried everything until now, the bike is still bugging! Very dangerous ! Sometimes the bike works et sundenly start to bug! He is selling it and doesnt want to buy a 2 Stroke injection anymore! I also wanted to buy the 300 sx but because of that I am buying a 250 Yz !
The Thermostat helps your engine to heat up quicker before it opens it up and lets all the coolant go through. Deleting it will just increase the time it takes to warm up the bike, plus remove the potential issue of the thermostat failing and overheating your bike due to it closing off the flow.
KTM are ruining 2 strokes, we buy 2 strokes because we want fun, cheap and easy DIY maintenance with zero electrical gremlins and these new TBI bikes are the total opposite of that. I bought a 2022 TC250 and that will be the last 2 stroke I ever buy. I just can’t trust these new ones
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.
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.
@@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.
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.
There are tons of these, I only showed but a handful. Also look at how many low hour TBIs are for sale for dirt cheap right now. There’s two groups on FB that you can find.
You cannot take that as an indicator. The entire market is fucked right now. You can’t give away a used bike right now damn near. People want them for free. Thusly the reason you see so many bikes up for dirt cheap right now. Not because there’s anything wrong with them. It’s across the board. All manufacturers and models. If you sell bikes you know this.
@@user-mo8tm4jw2l I agree the market is softer overall but there’s a ton of single digit hour TBIs for sale dirt cheap. I’ve had dealers themselves tell me because they can’t remedy the poor running bikes people sell them before a fox can be found. Plus ktm isn’t very helpful in this regard.
When u tip out a bowl full of metalic gravel its hard to assess what bit failed first.. crankshafts will chew up extra bits before they come to rest.. the way some of these new age riders treat their bikes i wouldn't even offer them a push bike to get home..🤣🤣🤣
@@gasnxt6805 I actually bought a 23 gasgas mc250, last of the carbed bike, adjustable powervalve. Only have a few hours on it but it’s as good or better then my TBI. And it’s consistently reliable.
My friend died riding his 23 300SX this past spring, he was having problems with the bike cutting out and it bogged on a jump face, cause him to wreck. While i'm not directly blaming KTM for his misfortune, but its evident that this models have been far from successful. I hope things will look better for the future of KTM
@@Nicky_Pin_It I’m sorry for your loss 🙏 If I’m hearing you correctly it happened at 207? I heard about this as well this spring. Shortly after we had two of our bikes cut out the same way. There was no fix from Ktm.
Wow, spending 12/13K for a KTM or Husky and find with such a major issues is disappointing. Go for a cheap GPX, or if you got money for a TM or Sherco.
I guess you haven't seen the TM's that blow up in less than 5 hours with crank bearings with blown and locked motors? Or the Sherco's with transmission gears blowing up? Or the GPX that melts down with nylon gears?
Interesting if the piston hit the crank under extreme load , I doubt ktm would off released it , Dino test should stuff them all, this reminds me of the xr400 days youtube says all xr400 cranks would blow ,but I never met anyone to blow one . Just saying.🎉
ktm has to get their head out of their ass cuz we all pay a lot for their "high quality austrian" bikes but they keep lowering production quality control which makes them have these issues. more recently they have been getting taiwan to make engine parts. Taiwan or even chinese produced engine parts isnt inherently bad, if the company puts a lot of money into production they can secure great quality parts and great quality control but Ktm seems to be lacking there. the electrical issues are purely from poor quality control and not putting enough money into testing and development (pocketing it all) and the piston/crank contact may just be a one time engineering mistake but still, we pay a lot so we want a good product. if i get another bike it'l probably be a kawasaki, yamaha, or honda until ktm stops this crap.
I have respect for KTM for keeping the two stroke going but in my opinion they have also kind of ruined the two stroke with all the electronic crap, rev limiters etc. I understand what they are trying to do but honestly some things are better left alone.
Thats like saying, "They ruined cars by adding the rev limiter and EFI." Rev limiters are there to protect the engine, and if any engine needs it, it's a 2 stroke. I've heard nothing but good things about TBI, and even one guy said it feels like a perfectly tuned carb to him. So don't give people that "oh they ruined it by doing this" because that's bullshit and you know it.
@@drpork1360apparently you forget to read the part where I said "It is my opinion" and yes I stick to what I said! Like I said I have respect for KTM just not a fan of all the electrical crap they have put on them even if it does make it better for some riders even though the biggest reason they put rev limiters is because they are using cheap parts, just look at all the problems they have now and how many top ends are doa or dead after a couple rides and that is with a rev limiter. I get what you are saying though and for some it is a good thing and I give KTM respect for furthering two stroke tech just not a fan of it, just old school I guess!!!
Well im in market at moment for a new 24 cant decide 300 sx or 350 sxf watching this video kinda makes my mind up i really fancy a 300 sx how dissapointing

@@stephenhumphries9550 ouch sorry to hear about your injuries, heal up fast! 350 is an excellent bike and a great all around bike as well. 300s are awesome when they don’t have problems, still I’m not a fan of the rev limiter and the fact that ktm can’t diagnose their own bike and consumer is left with a 10k paperweight in their garage. There’s a lot of new unproven tech, they need a few more years to sort these bikes out.
@@moto-x thankyou enjoyed your vids i always like to hear other riders input ...the 24 350s are great deal at this time of year and maybe bit more forgiving on this 56 year old body
Cant anyone open a class lawsuit? Ive had my 23 tc250 in the dealer and i turned it in with 16 hours due to random scary bogging, the bike now has 32 hour from them testing it and not being able to determin the cause. Ive had the bike and paying for it over a year only to enjoy it for 2 months. Its lieraly been about a year at the dealer.
Sorry to hear that, been there myself. Shame on KTM the parent for not being able to diagnose their own bike. It’s not the dealers fault, but it’s not our fault either! And as a customer who ends up with a 10k paper weight in their garage it’s a nightmare.
@moto-x I'm super cool with the dealer I've known almost everyone there over 10 years I go there just to hang out every saterday ( wife hates it) but I just can't believe thousands of people at this point have been scamed and there is nothing we can do, I really can't swallow that pill
@al-ew3mj well you struck gold then with this video didn’t you? Because I’m the owner, two bikes all my problems and a bunch of others problems thrown in to spice it up. Just saying…
I almost did and will have another one again. There’s something cool about simple bikes that just run reliably and are still competitive and that’s a yz250
lol! These bikes can’t take half of what a carb bike takes. There’s a difference between beating a bike vs riding it. In the video I’m holding the throttle steady and the bike is doing that. The bikes need some things sorted out to be reliable, when ktm can fix their own bike I’ll buy another one, until then I’ll stick to a carb.
I have a friend hew had this happen 2 times on his 23 and ktm said its his problem!! I'll never biy another one again!! And now there going to be made in China!!!!! Good luck ktm
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.
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.
The video at 2:35 is useless. Engine sounds normal. Why is he is revving the crap out of it? And the next video of the 250xc on track we can't see the clutch action but it looks like a fried clutch. He clearly hits the gas and it revs up high but doesn't go anywhere. Either his wheel is slipping or the clutch is.
@moto-x The XC sounds just like my bike at lower rpms. My bike has plenty of power at low rpms and his bike sounds just like mine. I can't hear his bike missing or anything besides it revving out, but we can't see if he's pulling in the clutch or not.
@@SpeedDemonExpress yeah may be hard to hear. He’s tried everything and still no remedy, neither does ktm have one for him. The first video is the bike being held at a steady throttle yet you can hear the surfing and cutting out. Spent 2 months at ktm with a ktm rep not just a dealer and they can’t diagnose nor fix it. Same thing to another riding buy Edy at 37 hours on his tx300. I hope you have great luck with yours, there’s just too much unproven tech and issues with these for me to go back for at least a few more years. I’ll take a carb reliability over the efi today.
*bogging (usually first thing to address is the simplicity of changing spark plug / confirm.) These absolutely have to warm up at idle upon cold start (*if that example of sitting immobile and revving to moon No Bueno)
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
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.
@@jamesoso259 do some research before you sound more like a “dork” as you put it lol. You obviously don’t know much about how engines actually work. All good though, stick to being a keyboard warrior 😂
@@moto-x lol 😆 do more research hahahaha so you’re trying to say the clearance in the engine changes depending on the rpm your argument for the piston hitting is illogical. You know nothing I get it it’s fine, you’ve never been on the right side of thinking.
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.
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.
@@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 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. 😂😂😂😂😂😂
@@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.
@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…
@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. 😂
@@drpork1360 you obviously didn’t watch the video lol. Both of my bikes were at ktm and they couldn’t figure it out! You’re obviously uneducated on the subject, so it’s pointless speaking with you. Anyway good luck with your bike.
If you rode like a man instead of a woman (but who can tell these days so your good), you'd prolly blow yours up too. Keep up b1tch ridin and you'll never have to deal with the problems the 1%'ers who actually know how to ride have. Good day porky.

Are they not pumping enough oil???
The biggest problem with today's engines is the high emissions requirements, which means they get too little fuel, which makes them much hotter because fuel also cools the engine.
these bikes dont run on homologation. they can emit whatever
Gotta picture off the crank assembly including piston to show us we have ?
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.

Yep, common for the flash but they fixed that now. Glad to hear you’re is going good 👍, hopefully it continues. Friend had the same thing, ran great for 37 hours then it didn’t.
@@moto-x sounds like your friend didn't have the same thing
@@dumbdumb572 he had the same thing happen to his bike, cut out off jump faces, wouldn’t run, bogging, intermittent.
I have had my 23 250xc for about a year. I rode it 2 times it ran horrible, heavy spooge, 9 hours and I've all but given up on this bike. It's frustrating to look at unfortunately.
What’s your mix ratio man it’s a 2t bike it wants 60:1 of either motul 2t or moterex oil only
@@yingyang203 60:1 the oem dealer ktm premix, crosspower i believe. I drained the tank after the 1st ride on the dealers fuel, initially I believed the poor running was due to bad dealers fuel. But no change with new premium fuel mix, then ethanol free made no difference. Runs great when giving it the beans.
my rm 465 runs just fine, no bs to mess up. more tech the more failures . cr 500 runs fine , all i hear is new bikes are so awesome , but when i txt them to go ride,,, lol can't bike is in the shop???? then just tell them ,, make sure you make that payment. some get upset because a 60 yr old flies right by them to. had a chance to ride the stark,, sweet until tech issues come. and no poker runs with it unless you haul around a generator with you. give me old school with belray
Makes me glad I have a 2019 carbureted model. :)
Hello i live in ivory coast and My friend got the sx 250 2023 all new last year. The first day the bike started to bug ! He has tried everything until now, the bike is still bugging! Very dangerous ! Sometimes the bike works et sundenly start to bug! He is selling it and doesnt want to buy a 2 Stroke injection anymore! I also wanted to buy the 300 sx but because of that I am buying a 250 Yz !
Ill keep to older carbed 2 srrokes sithout any uneccesary electrics
What I tend to do is buy secondhand bikes because I'm poor.
I would never buy first year production from ktm, unless I'd like to be a beta tester
So glad I got a '22 TX and not a Made in China model.
..just solved my dilemma and got me a BETA! 👍 😃
What does the thermostat delete do ?
I'm going to guess it gets rid of the thermostat.
Yeah, it's because the o ring at the bottom of the 'T' leaks and you can replace it or just go Samco and delete the stat.@@ronwest7930
The Thermostat helps your engine to heat up quicker before it opens it up and lets all the coolant go through. Deleting it will just increase the time it takes to warm up the bike, plus remove the potential issue of the thermostat failing and overheating your bike due to it closing off the flow.
@@peterreichert2104 Thank you. 👍
KTM are ruining 2 strokes, we buy 2 strokes because we want fun, cheap and easy DIY maintenance with zero electrical gremlins and these new TBI bikes are the total opposite of that.
I bought a 2022 TC250 and that will be the last 2 stroke I ever buy. I just can’t trust these new ones
I run 50:1 in mine just because I don't trust the 60:1. And I'll probably upgrade the piston when it needs it
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.
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.
@@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.
I got a honda but I'll show this to my buddy 😂
All the tpi haters out there getting a tad bit quieter now lol…great video!
My 20 Tpi has 190 hours has run great.
@@chrispederson4157 250 hrs on my 19, bike is rock solid with one top overhaul at 130 and still on the factory installed spark plug.
This happens when you make a competition bike with chinese kymco motors
Exactly
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.
I’m convinced it’s improper fuel mixture
There are tons of these, I only showed but a handful. Also look at how many low hour TBIs are for sale for dirt cheap right now. There’s two groups on FB that you can find.
You cannot take that as an indicator. The entire market is fucked right now. You can’t give away a used bike right now damn near. People want them for free. Thusly the reason you see so many bikes up for dirt cheap right now. Not because there’s anything wrong with them. It’s across the board. All manufacturers and models. If you sell bikes you know this.
@@user-mo8tm4jw2l Stop lying to yourself
@@user-mo8tm4jw2l I agree the market is softer overall but there’s a ton of single digit hour TBIs for sale dirt cheap. I’ve had dealers themselves tell me because they can’t remedy the poor running bikes people sell them before a fox can be found. Plus ktm isn’t very helpful in this regard.
When u tip out a bowl full of metalic gravel its hard to assess what bit failed first.. crankshafts will chew up extra bits before they come to rest.. the way some of these new age riders treat their bikes i wouldn't even offer them a push bike to get home..🤣🤣🤣
These bikes are way too expensive for this to be happening. Not worth it!
Until you get your 2026 ktm tb300 you could always just get a beta 300rr and enjoy the 2 years of normal 2 stroke life. Just a thought.😊
Was very close to buying a beta!
@@moto-x even i have to admit, the ktm engine with its balance shaft just feels so much better. I think beta need to follow suit.
@@gasnxt6805 I actually bought a 23 gasgas mc250, last of the carbed bike, adjustable powervalve. Only have a few hours on it but it’s as good or better then my TBI. And it’s consistently reliable.
KTM + Kymco = Junk.
My friend died riding his 23 300SX this past spring, he was having problems with the bike cutting out and it bogged on a jump face, cause him to wreck. While i'm not directly blaming KTM for his misfortune, but its evident that this models have been far from successful. I hope things will look better for the future of KTM
AND WOW, i didnt even realize it happened where the video footage happened(MX207)
@@Nicky_Pin_It I’m sorry for your loss 🙏 If I’m hearing you correctly it happened at 207? I heard about this as well this spring. Shortly after we had two of our bikes cut out the same way. There was no fix from Ktm.
@moto-x yeah Mike Manos happened 05/03/23 right on the backside triple. Sad situation
Wow, spending 12/13K for a KTM or Husky and find with such a major issues is disappointing. Go for a cheap GPX, or if you got money for a TM or Sherco.
I guess you haven't seen the TM's that blow up in less than 5 hours with crank bearings with blown and locked motors? Or the Sherco's with transmission gears blowing up? Or the GPX that melts down with nylon gears?
@@onthethrottle7104 I got a Lextra 300 2T ( GPX ) no problem at all. At half of the price of KTM.
Interesting if the piston hit the crank under extreme load , I doubt ktm would off released it , Dino test should stuff them all, this reminds me of the xr400 days youtube says all xr400 cranks would blow ,but I never met anyone to blow one . Just saying.🎉
Do some research, it’s a known issue… I don’t post stuff that is speculation.
@@moto-x I did plenty of research, and talked to heaps of boys running them , as with any model or make there's always a few lemons 🍋 .
@@bigals.ktms.9937 lol. If you looked you’d find these. Plenty of things have first year woes, these just happen to have more then normal lol.
@@moto-x i have lol
The biggest failure is buying a first or second design of any ktm..
ktm has to get their head out of their ass cuz we all pay a lot for their "high quality austrian" bikes but they keep lowering production quality control which makes them have these issues. more recently they have been getting taiwan to make engine parts. Taiwan or even chinese produced engine parts isnt inherently bad, if the company puts a lot of money into production they can secure great quality parts and great quality control but Ktm seems to be lacking there. the electrical issues are purely from poor quality control and not putting enough money into testing and development (pocketing it all) and the piston/crank contact may just be a one time engineering mistake but still, we pay a lot so we want a good product. if i get another bike it'l probably be a kawasaki, yamaha, or honda until ktm stops this crap.
How do a company alow carp like this to happen...
With the amount of money they change this should never
Ever happen...
I have respect for KTM for keeping the two stroke going but in my opinion they have also kind of ruined the two stroke with all the electronic crap, rev limiters etc. I understand what they are trying to do but honestly some things are better left alone.
Thats like saying, "They ruined cars by adding the rev limiter and EFI." Rev limiters are there to protect the engine, and if any engine needs it, it's a 2 stroke. I've heard nothing but good things about TBI, and even one guy said it feels like a perfectly tuned carb to him. So don't give people that "oh they ruined it by doing this" because that's bullshit and you know it.
@@drpork1360apparently you forget to read the part where I said "It is my opinion" and yes I stick to what I said! Like I said I have respect for KTM just not a fan of all the electrical crap they have put on them even if it does make it better for some riders even though the biggest reason they put rev limiters is because they are using cheap parts, just look at all the problems they have now and how many top ends are doa or dead after a couple rides and that is with a rev limiter. I get what you are saying though and for some it is a good thing and I give KTM respect for furthering two stroke tech just not a fan of it, just old school I guess!!!
I agree with you. Two strokes are supposed to be simple and cheap to run. They've absolutely ruined them. I guess there's still Yamaha.
Well im in market at moment for a new 24 cant decide 300 sx or 350 sxf watching this video kinda makes my mind up i really fancy a 300 sx how dissapointing
I’ve had both, from a pure trouble free customer experience I’d say the 350 for sure.
@@moto-x oooft didnt expect a reply but thankyou im in scotland injured at mo 3 broken vertabraes slight argument with other bike landing on me ( non fault) of course im riding 450 at mo but was thinking 300 or 350 but stsrting to look like 350 thanks for your input
@@stephenhumphries9550 ouch sorry to hear about your injuries, heal up fast! 350 is an excellent bike and a great all around bike as well. 300s are awesome when they don’t have problems, still I’m not a fan of the rev limiter and the fact that ktm can’t diagnose their own bike and consumer is left with a 10k paperweight in their garage. There’s a lot of new unproven tech, they need a few more years to sort these bikes out.
@@moto-x thankyou enjoyed your vids i always like to hear other riders input ...the 24 350s are great deal at this time of year and maybe bit more forgiving on this 56 year old body
someone should come out with a carb conversion kit for the tpi bikes
Cant anyone open a class lawsuit? Ive had my 23 tc250 in the dealer and i turned it in with 16 hours due to random scary bogging, the bike now has 32 hour from them testing it and not being able to determin the cause. Ive had the bike and paying for it over a year only to enjoy it for 2 months. Its lieraly been about a year at the dealer.
Sorry to hear that, been there myself. Shame on KTM the parent for not being able to diagnose their own bike. It’s not the dealers fault, but it’s not our fault either! And as a customer who ends up with a 10k paper weight in their garage it’s a nightmare.
@moto-x I'm super cool with the dealer I've known almost everyone there over 10 years I go there just to hang out every saterday ( wife hates it) but I just can't believe thousands of people at this point have been scamed and there is nothing we can do, I really can't swallow that pill
@@kevroq6139 I agree! If you have a bike that ktm can’t fix they should make us whole, period.
its always my friend or i know a guy that has these problems not to often the owner ,just sayin
@al-ew3mj well you struck gold then with this video didn’t you? Because I’m the owner, two bikes all my problems and a bunch of others problems thrown in to spice it up. Just saying…
Just by a YZ250. Sure its less infurier, but it works
I almost did and will have another one again. There’s something cool about simple bikes that just run reliably and are still competitive and that’s a yz250
its gonna grenade the way you ride throttle pinned all the time how long is the motor suppose to last under these conditions ?pinned
lol! These bikes can’t take half of what a carb bike takes. There’s a difference between beating a bike vs riding it. In the video I’m holding the throttle steady and the bike is doing that. The bikes need some things sorted out to be reliable, when ktm can fix their own bike I’ll buy another one, until then I’ll stick to a carb.
I have a friend hew had this happen 2 times on his 23 and ktm said its his problem!! I'll never biy another one again!! And now there going to be made in China!!!!! Good luck ktm
I’ll add to the list make better maps and measurement systems for 2t these behave awful.
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.
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.
Is this the new Chinese KTM 🤣🇨🇳
Carbs and kick starters
The video at 2:35 is useless. Engine sounds normal. Why is he is revving the crap out of it? And the next video of the 250xc on track we can't see the clutch action but it looks like a fried clutch. He clearly hits the gas and it revs up high but doesn't go anywhere. Either his wheel is slipping or the clutch is.
The video at 2:35 is holding throttle steady rpm… clutched aren’t fried. Listen to the xc again, its bogging, cutting out etc…
@moto-x The XC sounds just like my bike at lower rpms. My bike has plenty of power at low rpms and his bike sounds just like mine. I can't hear his bike missing or anything besides it revving out, but we can't see if he's pulling in the clutch or not.
@@SpeedDemonExpress yeah may be hard to hear. He’s tried everything and still no remedy, neither does ktm have one for him. The first video is the bike being held at a steady throttle yet you can hear the surfing and cutting out. Spent 2 months at ktm with a ktm rep not just a dealer and they can’t diagnose nor fix it. Same thing to another riding buy Edy at 37 hours on his tx300. I hope you have great luck with yours, there’s just too much unproven tech and issues with these for me to go back for at least a few more years. I’ll take a carb reliability over the efi today.
Learn how the bike works, i would suspect the 2nd injector is clogged.
Send me your broken unwanted KTMs, ill be riding that bitch next week
@@jangoreo well aware of how the bike works…
Wtf … I have 24 TX300 and FX350
That's what I would call an engineering fault followed by a made in China problem 👍
*bogging (usually first thing to address is the simplicity of changing spark plug / confirm.)
These absolutely have to warm up at idle upon cold start (*if that example of sitting immobile and revving to moon No Bueno)
Yep we’ll aware thanks 👍
Have you ever actually checked internal clearances or are you just repeating what you’ve read online?
Yes we’ve checked clearances. Have you?
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 .032-.035 on the three bikes we checked. 23 300sx, 23 TX300 and 24 300sx.
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.
@@path5362 that’s what we believe
Keep Taking Money.
they cant produce a reliable quality for 13000 bucks after all their experience.....triumph, ducati, stark varg are hopefully better
Convert it back to a carb model
I sold it and bought a carb model 👍
The piston is not hitting the crank lmao
You know nothing LMAO
@@moto-x you know nothing lol if a piston was touching the crank it would do it all the time not just at high rpm ya dork
@@jamesoso259 do some research before you sound more like a “dork” as you put it lol. You obviously don’t know much about how engines actually work. All good though, stick to being a keyboard warrior 😂
@@moto-x lol 😆 do more research hahahaha so you’re trying to say the clearance in the engine changes depending on the rpm your argument for the piston hitting is illogical. You know nothing I get it it’s fine, you’ve never been on the right side of thinking.
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.
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.
@@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.
@@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.
@@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. 😂😂😂😂😂😂
@@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.
Ktm 300s the most reliable bikes i know ever
Not the new TBI’s…
LOOOOOOOOOOOOOOOOOOOOOOOOOOL you have to be fucking kidding me.......
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.
@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…
@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. 😂
@@drpork1360 you obviously didn’t watch the video lol. Both of my bikes were at ktm and they couldn’t figure it out! You’re obviously uneducated on the subject, so it’s pointless speaking with you. Anyway good luck with your bike.
If you rode like a man instead of a woman (but who can tell these days so your good), you'd prolly blow yours up too. Keep up b1tch ridin and you'll never have to deal with the problems the 1%'ers who actually know how to ride have. Good day porky.
