Valve adjustment - need some expert advice.
Posted October 28, 2000 - 08:32 PM
Q. Should the flat side of the decomp shaft be facing the exhaust valve? Should it be pushed all the way into the motor?
Q. When reinstalling the cam chain tensioner, is it simple enough to let the tensioner "spring back" and unwind onto the chain? Does that make sense to anyone? What is your method for resetting the chain tension? I accidently stripped some of thread from the 12mm adjustment bolt. By using loctite on the remaining thread will that be enough? It does not seem like a critical fastener.
I plan to order the replacement valve shims this week and hopefully will have them in the bike by next weekend. Any further advice/encouraging comments from the likes of Taffy "cam master", James Dean "jet king", Clark "guru" Mason would be greatly appreciated.

PS. By wrapping the frame in a plastic bag prevents mud and dust from falling into the motor.

When I reinstalled the cam chain tensioner, I held a small screwdriver as best as I could and kept the tension off while I slipped the assembly into the cavity and then gently let go of the screwdriver. I could feel and hear the tensioner release but not all that violently. after snugging down the two anchor bolts, I then reinserted the screwdriver and took a little tension off the chain and then let it go again. I could tell that it was operating correctly. By the way, I oiled the tensioner before I reinstalled it.
That bolt is more of an access plug than anything else. As long as you have it sealed and loctited well so that it doesn't leak and won't fall out, you're fine.

you have relieved some of the doubts I have had on completing this job. I have never opened the top end of my bike before let alone muck around with valve adjustment. I'll let you know at the end of the week how everything turned out.
