    Cam chain tensioner? When do you know when it's time to replace it? On my 1985 ZL900 of course. When it sounds noisy?

    You can reset it per the manual. The upgrade includes replacing it, the guide, the chain and top guide with the parts for a 2006 Connie.

    Thanks, is a 2006 Connie a Concours? Does the Concours have the same motor?

    I understand you'll only have a problem with automatic adjusters if the RPMs drop too abruptly from high revs. The fast spinning camshaft pulls on the tensioner side which forces the tensioner to back off, stripping teeth off the wedges. After that happens, it can jump timing.

    :hello: I have a manual cam chain tensioner on my ZL 10 which was installed by the PO. I had to adjust it at 10 K miles then again at 20 K miles Both times I only had to go one full turn. Some guys go to tight. You only go enough until the chattering goes away. Adjustments should be done at idle. When the chain is to tight you should here a whining noise.
