manual cam chain tensioner upgrade

[bigbabee]

I want to install an Ape manual cam chain tensioner on my `79 gs 1000e. Do I merely remove the old auto tensioner then install the manual one or is there a specific procedure that I should follow? Do I need to have the motor at TDC before I begin the upgrade

I have one on my KZ750. There are instructions on the package. It seems to work OK. Takes a bit of adjustment to get it working correctly. There is a tendency to want to over tighten the tensioner. Once you get it properly adjusted it does what its supposed to do. I don't remember putting the engine at TDC just don't rotate the engine once you remove the tensioner. Basically you remove the stock tensioner, install a new gasket and bolt the manual tensioner in place. You need to turn the bolt on the tensioner to remove the slack in the chain and then back it off and tighten the locknut.

I have installed them on a couple bikes and you just follow the instructions.
It is pretty easy to feel the tension, as mentioned don't overtighten.

I'd put the engine on 1-4 TDC and verify the cam timing hasn't jumped after install. Wouldn't call installing one an "upgrade", unless you have aftermarket cams/springs, and run the bike at high rpm's regularly.

Like everyone mentioned, there is a tendency for people to adjust them too tight. One trick that i use, that isn't really the best method, is to adjust while the bike is running. As soon as your cam chain stops making noise, lock it down. Rev it up some, and as long as it's quiet, leave it set there.

I have also done this, its just hard to get at the adjustment nut with the carbs in the way.
