I would pull the studs though, and lap the cylinders deck surface, and the head as well...just to be sure everything is nice and flat, so you don't have any blown/leaky head gasket issues.

Hey Fox, thanks for the suggestion and sorry to get back to you so late. There is no pitting from what I could see. Is there a way I can lap the cylinder surface at home?

ecdeyzel:
Also a little update. I got new steering stem bearings and seals. Installed the races successfully, packed the bearings with waterproof grease and on they went. Used 2 halves of a close fitting PVC pipe to drive the bottom bearing down. It worked well. Will set the tension correctly once the bike has the wheels back on. :lol:

shop around the web...you may find cheaper shipping to your area through someone else.

Hey guys, check this out. I have an issue with the kick starter. The boss and the kick start arm are a miss match. I'm not sure if it's the boss or the kick start arm thats the incorrect part, but they clearly don't fit. The boss fits onto the engine though. A new OEM boss is heavily overpriced, as well as the whole kick start mechanism.

Any advice?

SOHC:
Could you get the kick start leaver welded up and grind and file it back to match the steel part?
