just rebuilt the top end on my 07 kx 250f and I had the head shaved down a bit at a machine shop I got it running has a loud clattering noise rode it for maybe an hour then I took it home took it back apart and the exhaust valves had cut down into the piston slightly didn't really damage it bad would this be from timing or because I had the head shaved down? it also drips oil out of the breather tube. any help is greatly appreciated.
The valves need to be shimmed more.
Why did you have the head shaved? Was it warped?
The Shop
