I noticed that you used a chain tensioner...Aren't those tensioners intended for the non roller timing chains? Seems like a roller timing chain. would eat into the nylon pads?
It does but then the wear stops once the rollers are making full contact. That being said I use the tensioners in tandem with the stock link belt style chain anymore--never have I seen a failure yet. As long as the chain isn't sloppy I'm starting to think double roller chains are somewhat over rated. J.Rob
