got it apart. the bore was too tight. takegawa/webike is processing the return. didn't crack it but smeared the piston skirt. replacement on way.




 
obviously not running lean:



no stuck rings:








I mean, a new cyl and piston are under 200 bucks shipped so no big loss. shame on me for assuming it was machined right being sold as a set.

2 stroke problems on a 4 stroke. lol.

The obvious solution is to re-power the poor thing. Got another LT250R engine?

I don't know what you're talking about. I merely pointed out the only logical and inevitable conclusion!

Go big or go home, right? Oops.  :lipsrsealed:
