Brother has a 13' XF1100 Turbo HC. He has 3'' exhaust, EVOPS three stage programming w/ launch control, EVOPS cold air intake and BRV. We ride in Michigan and out west so 1k-10k in elevation. He needs a clutch kit and wants to clutch it for his middle tune (240HP). What do you guys recommend, was going to call EVOPS tomorrow. He don't want a team tied. So looking for spring, helix and weight recommendations. Thanks.
