[QUOTE="blackduc98, post: 1188709, member: 65764"] It's very hard to tell from your photos, but it looks like a 4-point seizure. Assuming that you were not jetted overly lean, and you didn't have air leaks at the manifold and/or crank seal, then I'm thinking that whoever honed your sleeve didn't leave enough piston-to-sleeve clearance. Did your cylinder originally have a cast iron sleeve? If not, then did you account for the fact that aluminum piston expands more than the iron sleeve as the temperature rises? [/QUOTE]
