I need some advice on what to do for my clutching. 09 crossfire 800 141 slp pipe kit, powerclaw 2.25. Ride 0-7000 ft. and some 6-9000 and weight 170 with no gear. I was looking at torsional kits, but i need to have reverse so those are out. What can i do to improve my clutching? I was thinking shift assist and rollers, either rock or Hi Torque??? Should i change springs or helix, or are those better left alone with my large differences in altitude?
