    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Cam chain noise

Have been dealing with this for a while, some cam chain noise which gets louder with throttle. Did a top end rebuild on this engine this last winter, been running great and no noise till last few rides. Took the cam chain tensinor off two times and took apart and cleaned and reset knob spring tension, reset properly when installed( per manual). Seemed better but still noticeable. Took valve cover off today turned engine several times to check chain was tight. Nice and tight till get to "T" mark for 1-4 and right before "F" for 2-3, it is loose enough that you can push down on it and it moves a little in front of chain idler. Didn't know if this is normal? Checked every bolt inside and made sure all tightened to torque, that all were fine. Took idler off and checked chain timing, perfect at 20 pins. Checked valves all between .05 -.07. Did find a very small scratch on inside of cover right behind where idler is, saw no evidence of any scraping on chain. Even when chain is a little loose at top end it doesn't seem enough to let chain slap around. Measured gasket (can't remember if oem), is in great shape and not really very old, it's .073 in.(1.87mm) thick. Did check to make sure chain was still in spec when did rebuild and it was good. Even took left side cover off few days ago to make sure starter clutch or rotor was loose, seemed tight. Any thoughts welcomed! terrylee

I'm afraid that I'm not possible to give any advice but to ask a question instead:
Do you notice the sound when giving a little amount of throttle or only when throttling full?
I noticed the same noise last week (but not before) but only when I give a lot of throttle and it appears to come earlier when driving upward and with sozia --> with higher load of the engine.
Did you observe similar behaviour?

More noticeable at lower throttle, but if listen carefully can hear it at full speed. terrylee
 
No one have any thoughts? At least any on the slight looseness of the chain at tdc? terrylee
