Picked up a 1987 KDX80 to fix up for my son by christmas. Bike is in good shape and even has a Works Performance rear shock. Well it would not start as it only had 30psi in the cylinder. Today I removed the cylinder only to discover it had a stuck ring and it put some nasty grooves into the cylinder. The piston in the bike is a 514P2 Wiseco and it is 48.50mm. I see there is a 49.00mm piston available but I think the gouge is too deep. Been looking for a used cylinder but they seem rather hard to come by. There is one for a 1980 KDX80 on Ebay. Will this work? If not any ideas as to where to find a cylinder?
