What was ur bike doing mine is bogging down under load so im splitting cases to see what went wrong im thinking a seal is bad im changing all seals an mabey the bearings i have yz125 2003 same engine as urs
Mine lost all compression and wouldn’t run, I had the ring seize due to a lean condition from a ripped carb boot. You definitely could have a bad crank seal that’s pulling oil into the cylinder. Good luck with the tear down!
