I'm designing the eccentric tensioner for our car this year running a Yamaha YZF-R6 engine, but I can't find any information on the 'magnitude' of chain elongation. It's a pretty situational thing, since good lubrication habits can reduce it to it's minimal. But does anyone have any data on the elongation with respect to distance run, for example? Then I can easily get the incremental angles to adjust the tensioner.
