Transmission works great. Small repair on case near counter shaft was done well as it doesn't leak oil. I ran this engine for about a year until it quit on me. Sold the bike with my other engine so don't have use for this one. Crank is questionable but spins fine. Full clutch included. Clymer owner's manual & miscellaneous parts also included. Power valve is missing a few parts. Will separate top end if needed. Used piston with minimal damage included.
