Change out the piston now to avoid it, get a forged pistonn if you look up JBub Ktm on facebook he has the fix for this. If u watch my other video of splitting the cases you'll see it even broke the cases
@@thedirtdigger5990 on the RHS of the power valve when your setting the Z height it looks like the carbon is polished off. This is what I’m seeing in mine.
Oh that’s just lovely. Just bought a new 24 250sx. Swear If this happens that early I’m gonna lose it!!

Dang
My thoughts also
I have the same issue with mine. Done 13 hours. Looks like the piston ring caught the power valve. Looks like yours also caught the ring?
The powervalve didn't look like the ring caught it but it's possible

@@J4M54UK actually I had to polish that part because some of the aluminum chunks of piston had messed it up and lodged it open
manufacturer error or lack of maintenance I wonder?
I think the piston hit the crank. There's been quite a few of the 250s and 300s having that issue
Good to know, thanks.
