I've been looking into pulling the cam cover off my 2000 Fatboy engine to replace the inner cam bearings, since mine are the ones that did not get upgraded in mid-production that year, as verified through HD. Bike was bought used with no history of maintenance known (Hock Shop sale). I am also looking into tensioner replacement, if needed. I noticed the material for the tensioner is now a reddish color, instead of the yellow in all of the pictures I see, ie., link; Harley Twincam Secondry Cam Drive Chain Tensioner 99-05 Also says the new part #'s replace the old. Does anyone know if this material is any better or worse? Maybe just a color change? Anyone know?
