[QUOTE="jumpingjoe628, post: 1017252, member: 59921"] I was wondering if the 78 CR 250 cylinder wall was plated or sleeved. I want to hone it out and install a new set of rings. I already have the rings, and the piston and the cylinder looks to be in good shape. But there are a few scuff marks that concern me.I plan on racing this bike in ACR events pretty hard as an expert, but I will do regular topend maintenence on it so I just want to get a few more practices and a couple of races out of this configuration before I start replacing parts. I took a couple of pics to show as well. These were taken on both the intake and exhaust sides.
