I have a 2014 550 XT that I'm doing some clutch maintenance on. Being a snowmobile racer for many years, as I'm working on the clutches I'm thinking of ways I can improve clutch performance. The ATV clutches are a little different than what I'm used to working on. Have any of you done any clutch tuning to the 550's? If so, what did you do and how did it effect performance? Thanks for your help!
