You need to contact whipple directly. They only make a few at a time. Below is where I had my pulley coated.Where did you get the Whipple Adjustable Idler I looked but couldn't find one. Also where did you get the pulley carbinite coated. I think I'd rather do this than a lower. I just like the idea of having a caged lower.
