Hopefully I have the right person here! I heard somewhere on the forums that you have done alot of testing with clutch setups for the pro rmk. I have a 2012 and ride alot at 2500 to 5500ft here in BC. Most of the riding I do is around the lower end of that. I am a heavier rider in the 235 range before getting dressed. Its all stock except for an HPS can and I have just changed the gearing from 20/42 to 19/43. What do you recommend?
