    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...

  • Returning Visitors

    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.

Having problems adjusting the cam tensioner

So on Saturday I took of the cam chain tensioner and followed bwringer's advice on setting it. Put it back on and the engine became really quite like normal. Went for a 100km run and the cam started making noise again. Any ideas why it would not be keeping the tension?
 
There are parts inside that can wear as well as springs that lose tension. If the initial startup is quiet, I would suggest then loosening the locknut on the side and taking the bolt in until it bottoms (thus locking the plunger in place), and taking the locknut down after that. This is where it would be locked if you had a manual adjuster. I would call this setup automatically adjusted/manually locked.
 
I have heard of the tension not being enough for some bikes. So they would change to a manual tensioner. Which is the same only you screw in the bolt to hold the tension.
 
Well, we had it apart to replace O-rings and while doing it also replaced the spring inside. Up to that point it worked flawlessly. No idea what is happening at this point.
 
The external spring on the large plastic knurled knob, did you put enough tension on it.
I found I had to put 2 turns when I rebuilt the one on the 650!
