February 23, 200620 yr Any Ideas on taking off the fly wheel on a TY 80 if I do not have the specific Yamaha, puller bolt, extraction thingy?
February 23, 200620 yr you need the right puller, can damage the cases or the flywheel. It is a generic japanese, 27 mm LH thread if I recall correctly. Dennis Kirk has them maybe $15 or 20. You may need a spanner to hold the flywheel from turning also, I made from a bar stock with some pins. Also made another one by welding bars onto an old vise grips. kcj
March 3, 200620 yr Author My latest problem! I have removed the flywheel on TY 80 and it has had a lot of corrosion/rust from mositure. With a tight flywheel spinning, no spark, but if I pull the fly wheel off the shaft a little ways then it begins to spark very well! I have lightly sanded with black fine sand paper some of the rust off the point of contact on the flywheel where the points arm rides, still no spark. Any Ideas? sam
