Doorstop. Between the seize, the blowby and the fact that it started life as a 20mph cylinder, it's not worth doing anything with.

Re: This piston/ wall still good or nah?

theres scores of scores. the only thing is w any upgraded cylinder youll have to take out that nub in the case.

Ha . That looks like a bit of fun . See what you can get out of it before throwing cash out the window .

I'd hone the cylinder . Clean and carefully open the ports a little , at first .

Clean the piston ( remove any high spots on the skirts ) . Relieve the piston crown at the ports .

Clean the head and take some off to increase compression .

Clean the exhaust and maybe open it a bit .

Might have to lower the needle clip .
