Finally getting around to my '85 CR500 conversion, and opened up the motor last night. When I bought this bike, it had low compression, so I never heard it run.
Now to the topic:
The sleeve appears to have spun nearly 1/4" inside the cylinder(I'm guessing). The bore is stock at 89mm, so I'm thinking whoever bored the cylinder out for the new sleeve had their clearances wrong, and as the cylinder got hot, the sleeve torqued a little. Have you guys seen this before? Im hoping the cylinder can be bored for an oversized sleeve, and everything will be fine.http://uploads.tapatalk-cdn.com/20160706/0daffbb1878d6e99e2bbb99de4a0d725.jpghttp://uploads.tapatalk-cdn.com/20160706/a6ac2bcdeeed8339471d680e264aeb06.jpg
