Immensely helpful, cant thank you enough for taking the time to do this!! Definitely learned a lot! I will be getting myself hook spanner, I will check out the FB group. Love the advice about boring the head to fit a KX60 cylinder/rings, i've heard that finding a cylinder was a big headache so I'll take your advice and go the KX route. And thank you for the heads up on the linkage bearings, I'll press those out and replace them. I do have a questions about the swingarm "bearings" mine appear to be just collars and bushings with no bearings. I'll send you some pics via email, but please no rush on any response, this is just for fun and I really appreciate your time! Happy Days indeed, thank you man!
