l think this is a great idea, can you please post details?I think the point is being missed here. Correct me if I am wrong, but like the final drive chain, the driven side will always be under tension when the motor is running, so the valve timing will not change.
The function of the tensioner I would have thought is merely to stop an overly slack cam from slapping around as heat expansion and wear occurs.
So, my answer would be to set it on the loose side and forget about it for 10,000 kms. I have regularly popped the valve cover to check the CCT, and the adjustment required is minimal. FWIW I have cut a longer internal rod for the CCT so that if the ratchet ever fails, the plunger cannot retract enough that the chain can skip a tooth.
