was wondering, i have a barely used ST 3000 with a busted ring, and a chip from the edge of the piston. I was thinking maybe a piston, ring , and liner from a ST 3250 would slip in there.?. The tech guy at Supertigre could not say yes or no.
What do you think? Has anyone else tried this? Thanks, George
