Thank you all for response. I think I was a bit vague instead of painting the whole picture and went straight to the point.
And the picture was a bit bigger indeed.
Biltonjim, I've researched the subject but didn't find scotch's conversion info (thank you!). I just remember him making a list of 'must things to do', and one of the first was to scrap the supplied automatic tensioner, as it is a failure waiting to happen. The ZX11 tensioner - I found out about it after I've already bought the manual one I have. Why not to use it! It wasn't cheap! So, after my searches and reading done, I still had a question particular to my own circumstance.
Today I see scotch's new mod - great! Yet another new chip added to the learning curve. Am I going to do it - but not right now. I am trying to make the one I have working.
I've tried a few approaches but without previous hands on experience, I just have no idea about that 'sweet spot'. What might seem like an obvious one to one person, might not to another, especially one with no experience. Even Formula 1 drivers practice moves a lot, and some win and some loose.
I didn't follow the resetting and trying the original tensioner because I have no experience with it and couldn't really have a piece of mind reading what I see as a result of this experiment. It's an old piece which has a reputation for failure. I have no idea where mine is and what it delivers, I don't know it's history except that of sitting abandoned for 30 years in some shit environment. It's a crucial and a sensitive little gadget. What result would I get might not be equal to a properly working one. Therefore I left it alone searching for a solid measurable answer.
So.. where are we now.. Kawboy, I actually measured how far there is to the chain with a wooden stick, how far there is to see the chain move when poked. I screwed the tensioner that far. Would that be THE 'sweet spot'? Seemed loose. When tightening the tensioner further I can move it inwards quite a way. We are talking millimeters of course. Thus it feels like I am sort of shooting ducks in a dark.
I know it's not easy to pin point the absolute correct answer because all sprockets and chains are warned out to a different degree in all different bikes. What I am used to is measuring how much the chain or belt travels when pulled or depressed, and I was hoping there would be this kind of measurement applicable here as well. Maybe there is, but I haven't found yet such info.
I will be playing with it more. The pistons stay at the top dead center for a bit longer!
A question still lingering in my head is - is this tensioner to simply limit the straight line of chain from moving away from gears when spinning (preventing the discussed fatal jumping the teeth), or also applying extra tension ? Based from what I read from you guys, it is the first (based on advise of not going beyond the light contact and even backing off a tad).
Is this what you meant scotch?
NEVER tighten the CCT with a wrench on the Bolt-Head !!!! My personal experience has always been to turn the BOLT in by hand !! Using a wrench on this bolt will most likely over-tighten the adjustment !
Sorry guys for what might seem like a broken record, but I am still processing
