new trail 125

[m in sc]

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 was going to go full 500cc quazilla.



however the replacement cylinder & piston showed up today. from japan. i ordered it sat upon warranty.    going to make damn sure the cyl clearance is at .002" this time, because it sure the fuck wasnt last time. .

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.
