I've had my 600T for 2 years now. Around 500 miles on it. One thing that always sort of bothered me was the high RPM engagement of the clutch. Most of the trails on my property are steep, slow, and technical and the machine seems to need to rev pretty high to move at slow speeds. I understand this is normal and how these bikes are set up. Is it possible to change this with a MSC clutch kit? I am willing to give up some top end for the sake of gaining bottom end and torque. There are different stage clutch kits. Which would be best to accomplish my goal?
