Valves

I finally got the girl back together last weekend. Installed new shims, brake and clutch lines. When I started it up I had to shut off right away. Lots of valve noise from the rear cylinder. Removed the tank and rear valve cover. Low and behold the exhaust cam was off one tooth. Corrected the issue and now she sounds great. Can't wait to get her out on the road.

Next time I'm going to pull the radiators. By then I'm sure the it'll be to re-seat the valves. Ugh, not sure I'll be up to pulling the heads.

The gear drive did make it a lot easier. When I first started her up I had to kill it quick. Lots of clatter coming from the very cylinder. The rear exhaust cam was off by one tooth. I blame my assistant for distracting me.

I do have a worry, after a few heat cycles would the the cam retainer bolts need torquing?
