After uploading the first video, I received many messages from people that they experienced the same problem with their 2023 model, now I don't know if the cause is the new KYMCO cylinder. Also, the S3 low compression head caught the attention of many people, and they ask me if it happened because of her. I wouldn't say, with it even the life of the engine should be extended because it creates less compression, there is less resistance and the whole machine becomes more relaxed. If I had installed the S3 high compression head, then it would have been the other way around, then it would probably have caused the rings to get weaker sooner on the piston. But certainly, it wouldn't cause the piston to blow up.

This is obviously a bad material used for production, because the same problem is repeated on several engines. Which means that I didn't just have bad luck, but that there is something hidden there that we don't know yet. I want to work on this topic a little deeper and find out what happened to the KTM EXC300 TPI 2023, because the same engine is used in the KTM XC-W300 2023, so that is important for many people in USA also. I would like the most if this happened only to me and it was my fault, so that all the other riders don't have to worry about this. We riders must stick together, and if there really is a problem, let's divide it among ourselves and try to find a solution to prevent this problem in time, when we save one KTM TPI 2023 RIDER from this happening to him, I think we have succeeded a lot. Because parts are expensive and it is not easy to set aside money for repairs.

If you want me to investigate why this happened, leave a like on video
Are Kymco cylinders on all ktm exc/xcw 300 2023?
The kymco cilinders is ok,my apinion. Something is problem with pistons???
How many hours on that engine?
Yes please! My '22 ktm 300 xc-w just did the same with 79.2 hrs... Let me know what you find and how you diagnosed please!
Your video just saved me a lot of money. I was going to buy a new KTM 300. Now I will look for an older one. Thanks man.
You cant write off a whole era of bike because one guy on the internet had a problem. There are 10s of thousands of these bikes out there without issue.
@@dirkdiggler3009 I didn't write off a era. EFI is great. My truck motorcycle and snowmobile all use it. I found a 2013 KTM for 4 grand. A 2023 is $ 13,000. I have the electric start problems and out dated front forks and shock. I don't want to risk it with the engine. I'm old this will be the last dirt bike I need to buy. My riding days are numbered.
@@TheXcr800dude Myself and my friends all ride TPI bikes. All up we have over 1000 hours of ride time on these and nobody has had any issues outside of standard engine wear. If you have them adjusted correctly, warm them up before riding them hard, and use the proper oil filter maintenance techniques they are very reliable. If this is the last bike you will ride the treat yourself to a smooth running bike. You are still going to have to maintain it. You can take your money to the grave.
So glad I switched to Yamaha after 30 years with KTM. Very happy with my 22YZ250X
I'm going to get a YZ250x too but ill keep my 19 300xc
I would have done exactly the same. There is something wrong with this whole KTM TPI thing ? Stick with the carburetor bikes. 👍
04 WR450f built to YZ top end wise, WR crank and flywheel on bottom. Best bike I've ever owned. Supermoto street legal build and drive it like its stolen everytime, Yamaha is as solid as a rock. Only one who i feel like even compares is Honda. This is my opinion though. Don't get your little orange panties in a twist love every bike really, and have owned many too, yamaha/Honda is all I will touch these days! 2 wheels 1 love ride safe
If you bought a YZ 30 years ago it would still be nearly identical to the one you have now, it’s a great bike but they just forgot what innovation is at Yamaha
Excellent video. Just imagine those of us who do not have the skills to fully repair an engine and have to pay to a local dealer for the repairs 😞
Great point! At least I will save some money, because I don't have to pay a mechanic.
It’s called B,O,H,I,CA. Bend over here it comes again
So change your piston because this guy tried to get too long out of his, entirely ignored ktms recommended service limit
the newest ktm models don't have the good quality pistons like previous years, they often shatter after 60 hrs (wich is not a lot for a tpi bike), alse the cyl are made by kymco.. so yea its a no go 4 me on the 2023 ktm's
@@movitiate7634 my '22 failed at 79.2 hrs... didnt even hit the 80 hr recommended piston interval.
I’ll happily stand corrected if I’m wrong but didn’t you say in an earlier video that you had 100-200 hours on that piston?
I find it strange that enduro guys go that long on service life compared to mx, where I got shot down in flames on social media for having a failed piston at 35 hours.
What do ktm recommend for the change intervals?
I know that vertex recommend 40hrs max for enduro on 250cc+ pistons.
I know enduro isn’t as hard on engines, but those hill climbs must take their toll.
they say 80 hrs.. mine blew up at 79.2 hrs ironically.
Like the engine stand, never bothered using one rebuilding bike engines but that looks a lot easier than propping it up on a couple bits of wood lol. Fortunately my carbed exc has proven rather reliable lol
I've also often worked without this and it's really possible without a engine holder, but with this it's much easier. Especially since you never need the help of another person to hold the engine while you take something out
@The Dirtbike Rider the reason for the drop in quality is because KYMCO is produced in Taiwan compared to Elco in Austria.
I think I spoke to you before about the dealer here in Australia lying to me saying nothing had changed on the EXC's since 2021. Which I then found to be false when visiting another dealer and looking at a 2021 bike with an Elco head, while all the 23's had Kymco.
Theres a reason there going to TBI and pre mix. In really wet conditions around here were seeing more starter failures too.
I agree, TPI did not prove to be the best model
It must be nice when you know what you are doing, great video.
It sure is, But believe me, my heart hurts when I disassemble my 2023 tpi
Thanks for giving me the run down. I just had this happen to me on a '22 ktm 300 xc-w with 79.2 hrs. Let me know if you do a rebuild video. Thanks! Also, how are you going to diagnose the root cause? As I am a little disappointed with my bike at the moment (I have the engine out and ready to tear down once I get the right gear/flywheel pullers). Can you inspect the injector?
Seen two of these now in the same condition BOTH had aftermarket heads.
I just had a 2023 ktm 250sxf lock up on me today. 25 hours total on the bike and meticulously maintained. Oil filter and oil changed every 4 hrs. Air filter constantly cleaned. All fluids consistently topped off. Majorly scratching my head, I figure I just got a bad engine from manufacturer.
Put a wiseco forged piston in it and never have a piston explode again
Unreliability s a common problem with KTM. All the forums are full of KTM horror stories since decades.
The word KTM gives me skin rashes when 40 years ago a 250 GS Enduro ruined totally my 83 racing season. I had all from engine failure, gear box failure, broken frame, to oil pissing rear shocks. KTM didn't gave a shit. The official KTM bikes have little in common with the production bikes; so they can win, otherwise it would break.
After paying the debts caused by the KTM, I bought on 1984 a used Honda CR 250 prepared Enduro. I made a complete season with the same piston and cylinder and not a shadow of problem. After I stayed with Honda, none 2S or 4S gave me trouble. The XR 400 R of the nineties was as reliable as a truck even with a 440 cc kit 38 HP at the rear wheel and you could make complete seasons of competition or long distance raids with just good maintenance.
I am suprised KTM doesn’t use Austrian or German cylinders and pistons anymore. That’s like buying a Japanese brand bike and getting Taiwan parts in the motor that would be sad.
All of that crap is made in India now.
Now i am 100% sure that my RM250 wont left my yard til i die
I believe Kymco is Taiwanese (although I'm sure they have factories elsewhere).
Pretty bad when you pay so much $$ for a new KTM just to buy new generational unreliability built into such an expensive package.
But Dirt Bike Channel will brag that bike up to no end....
Excellent video this will show all thats brought a 23 pumpkin model how to strip it down when there piston brakes up
Thanks for the advice, I was thinking about the forged piston, what do you think about it?
56hours on my 23 300xc tbi and the bottom end has a hole through the case.
Nice work, i'm really interested in know what happened
Какое топливо использовалось? Похоже на детонацию
I also think that the problem is in the piston
Was this not covered by warranty given the low hours on the engine?
me happend the same by a 2019 250 sx. + damaged engine cover in the area of the intake and broken zylinderhaed to :( i used a vertex piston and this happend after 44 hours by fullgas hahaha :D
and it happend with the elko zylinder, i think the problem is the piston konstruktion .
shame KTM for using poor parts...i remember my guys years ago, they had KTMs with Nicasil cylinders and they could go with the assembly over 100 hours of function...this is unbelievable....this days it seems the more new the bike it is, the more problems and fails occur...
Some people say there might be a manufacturing error in the 2023 piston. Still they are cutting costs definitely on the 2023 model.
@@Taitohaukka I would believe so maybe with the material of the piston or possibly even the design if this failure was under heavy load..
Stop with the blasting music !!!!!!!
3:20. See I tell everyone 2 stokes have different colour power bands in the engine! 😂😂😂😂😂😂😂😂
I was curious if you didn't set the squish band if you think maybe the Piston impacted the new cylinder head I said you have put the high compression head on there it was curious if you thought maybe that was part of the issue or not
I used a head with less compression, the measurements of squish were checked and everything was ok. This same head is also used by many top racers
Ktm are using cheap pistons 60hours then pop am I right?
Idk bout that but I heard that some people suspect manufacturing errors in the 2023 piston. Had a 300 ktm that wasnt 2023 and easily went 160h with one piston.
let me guess. you heat cycled the motor?
Should have stayed with beta
I'm going back to the beta, brother
Did you decide which kind of piston to use? Forged or cast?
I am doing research but for sure i will not trust KTM pistons anymore. There are some good stuff in germany, i will let you know when i know. Also i am talking with few riders which are top 50 at erzberg rodeo. So i will follow them and what they are using.
@@TheDirtbikeRider Ok thank you. I am worried about this too. I have the 2022 GasGas EC300 with S3 low comp head, idle screw mod but no special ECU.
@@lostinpa-dadenduro7555 I see you’re in PA? does your tpi feel lean when you rip on it up a hill climb? Mine feels lean sometimes. 22’ te300i. Riding around RORR elevation
@@stevenllewellyn8906 I’m riding at FRO. I don’t think it feels lean. I did the idle screw mod and I adjusted the air bypass screw towards rich, and then adjusted the idle. I have various videos on my channel. You can examine the sound of my grandpa riding. 😄. There’s a video called the Megs Eric Warmup where we hit a steep hill at the beginning of the video. In that video I have all my mods and had been riding with that adjustment for awhile. Also in the video Sh1t Burrito at 7 minutes 51 seconds I go up a long steep one.
@@lostinpa-dadenduro7555 haha I’ll check it out. I just rode at Locust Gap yesterday. I have the idle screw & air screw mod as well. Just a fmf turbinecore silencer. Stock tuning. Maybe I’ll play with the idle and air.
Ktm group is 👎👎😤🤮anymore ,money money but quality is getting donw
Yup
Yea
They are made in India...like Husquarna...both have cheap smell
what changes does the aftermarket head? If the compression has been increased, it might caused this failure?
It’s lower compression head
Why would you put a lower compression head on a brand new bike? Are you having issues with detonation or have to use lower grade fuel? Is there any chance that foreign debris may have gotten into the cylinder when the head swap was done?
That bike was some metal fense or aluminium bowl in India.....the material have cheap smell
I've heard stories that a lot of KTM parts are made in India, but I can't confirm that
@@TheDirtbikeRider The dealers in my state told me the story that last 3 years ktm comes from India
@@TheDirtbikeRider I believe Kymco is Taiwanese and has factories in Indonesia and China, not in India.
23 ktm 300xc 56hours just blew a hole in engine. Bottom end.
Did you check the squish band when you put the new head on?
Of course I did, it was accurate according to the dimensions listed in the ktm service manual. And in comparison with the original head it was same and perfect !
@@TheDirtbikeRider that makes me wonder if this is a problem with vertex then. Maybe just a bad piston or couple
@@TheDirtbikeRider How about the mapping or timing?
🔥🔥
Unlucky. Air filter maintenance and warmup.
This video is misleading. Its obvious that the engine is not stock and have been modified. If would be nice if that was disclosed and the modifications were listed. Anytime you change stock parts or settings you run the risk of reliability problems.
At how many hours did it fail?
14 i think it said in the first video
@@Tpitill I think in the first video he responded 111 hours. Should be perfect at that time, still.
On my old 19 tpi i took the first piston out at 250 hours and was still putting out 175 psi 👌
Great Skills! Is it possible to go to HARD on your Bikes?
Sometimes, I wouldn't say that I'm too fierce or too gentle on the bike.
👍👍👍👍
Anyone know who makes the spikey filters?
Funnelweb filters
@@brentrutchick9381 thanks man ✌️
funnelweb-filter.com With FWF, i don’t ask myself if i need to take a lot of filters when i will ride few days; i know one filters for many days is enough!
Absolutely shameful KTM put out such GARBAGE ! My 1976 RM 125 went through years of abuse between top end changes and never too a 💩like that !
Just goes to show, complexity is the enemy of dependability!
Ktm warranty? Or he knows the product is not ok😀
Just a bad batch of Vertex pistons?
Well I will NEVER EVER buy a VERTEX PISTON!!!!
Just another failed KTM living up to its reputation
It's strange but in conversations with fellow riders I predicted that. I was quite sure that the gas crisis in Europe and high electricity bills would also affect KTM and they will try to do some short cut saving in production and materials. !!!
Sorry, but there is NO EXCUSE for this happening on a new bike. Absolutely unthinkable for the price they are asking for these bikes. KTM you will pay the piper for this kind of penny pinching, and for cheating your customers out of their hard earned money. 😞
shit dude, why you still with ktm? you had beta, sherco, but you got back to the orange.
I have fixed LOTS of 2 stroke engines in my time (and 4 strokes too) I have never seen a piston covered in carbon when it’s almost new . It’s time for KTM to make you a visit. Hopefully they serve you with defamation court proceedings,
Well at least it was an easy fix!
It is easy to fix, but the problem is that it is expensive
Πάρε τμ να μην έχεις αυτά... Πιο ψεύτικα από τα ktm δεν είναι ούτε τα lifan. 😆
What’s your email my ktm locked up and blew the bottom case out
How many miles? What year is engine?
2023
I bought it 3 months ago, 2023 model and it has about 2500 kilometers
