Hey all,
Has anyone had their valve cover off recently and can give a general sense of how tight the cam chain is when using the OEM cam chain tensioner?
I have a manual CCT and recently snugged it up a little tighter because I was getting more valve train noise than I was used to. My last few rides have returned lower than average MPG and after reading some threads online I'm wondering if I over-tightened it.
I adjusted the chain until it was tight but not fiddle string tight. Similar or slightly tighter than the freeplay seen in this video:

I could still easily turn the engine over by hand by spinning the back wheel in 6th gear. Did I go too tight? Am I damaging anything?
Personally I would delete the manual tensioner, and fit a new standard Suzuki one.
The standard tensioner has worked perfectly for many many years, why imagine you can 'out-think' the Suzuki engineers.
I've seen the mess a loose camchain can make to the inside of the engine... bent valves, damaged pistons etc. Don't risk it!
When you hand crank the motor there should be no point in the cycle when the chain sags between the 2 sprockets.
Cool.
Buddha.
