Just purchased a bunch of used yamaha parts. In the batch was this 61x ported cyl.
no idea who did it? Its basically race porting. Probably home done?
its not terrible and should run ok. I put a quick hone thru it and bore as is can be run.
not perfect by any means. Its has wear. Current bore is 82mm
selling as is! $150 shipped cont US
