Being new to my max I have noticed one of the first mods was the chain tensioners. I stumbled upon these from Richards Relics and installed them. Installed very easy with good fitment. For just the fronts, pricey at $105.00 shipped. I have road it a couple of times and they seam to work great. Richard stated that the roller itself should last approx. 300 hours before replacement ($15.00). You guys probably already know this, but I thought I would pass my thoughts on.
