So i just finished my 2007 rm125 build and i have around 3 hrs total on the bike and I’m now on my second top end. The first blow up had me replace everything up top so it’s l now oem stock. Brand new cylinder, head, piston and power valve. So it blowing up after fresh oem parts has me confused. It looks like it hit the power valve. Any ideas?
This is the first blow up
Looks like blowby on the piston. Was ring to cylinder clearance correct?
