Alright, just went on a 30 mile technical trail ride on my YZ 426. Good thing I put in a new clutch!! Most people buy a WR and convert it, I am trying to go the other way. I am guessing that a weighted fly wheel is a good way to start. I'll do the gearing second? What I wanted to know is how much does a fly wheel weight help, and how diffacult it is to install? Tired of feathering the clutch!!
