Go with the nika-cell, buddy. It is perfect fix for your problem. Hope you don't have to wait for a month to get it back like I did. They hone it out fill it in and machine it back out to stock spec's. I had some damage to my ports and still come out ahead by having them fix it. Fresh, stock-cylinder with a new piston, and a little time to clean her up, oh heck ya. Put on a nasty back tire with the money you save!!!!!!
