Thats your choice.... I'd never run any marginal parts in my motor for fear of ruining a cylinder or a case.

I'd imagine parts in Canada are harder to get too if you launch the motor.

Whats a bore and a piston 175$?? Or better yet, upgrade that bad boy!!

You need a program that reduces picture sizes. May be easy to find one at Downloads.com or some other gys here probably know where to get an easy one...

A piston is just a carrier for the rings, some little scratches in the skirts of the piston wont hurt anything, as long as the ring grooves arent worn id say run it.

why did u take it apart? was it loosing compression? i would never put a piston back in unless it was tight in the cyl. and only if i couldnt catch the scratch with my fingernail same with the cyl. because it will just damage a new piston
