Topic: How to tell if a Chain is too Tight?

[LoopsAndLogic]

With the engine running, how would you tell if the cam chain is too tight??

At idle, I barley here a whine, but with the engine running at 2k, I can notice a small consistent whine.

And when  you rev to 3k or above and I let go for the throttle to come back to neutral, you can definitely here the chain whine.

 Is this all normal?? I've never manually adjusted a cam chain before.

Which Model are you talking about first of all. The adjuster mechanisms differ somewhat from model to model. However, the SOHC-4's are not "manual" adjusters - they should be more correctly referred to as "semi-automatic" IMHO.

Too tight a chain is not generally a concern with these type adjusters as too loose of one- meaning they will only go as tight as their internal springs will allow, but will wear loose if not properly adjusted according to procedure, or if the mechanism is worn or faulty. Theres a post in the FAQ's under Engines on camchain adjustment that says it all.

I thougt the rule of thumb on this was to sit on the bike, "not running" and lift the chain with your finger.
1 inch or so of play is about right.
