Trying to help out a buddy with a 08' XP w/ Boondocker nitrous kit. Any info on what gearing and clutch weight settings would be a great help. Sled is geared down ( not to sure what it's geared down to but has stock gears in trailer ) and is hitting the rev limiter when on nitrous. He has adjustable clicker weights and primary spring # 415034900. Any help is appreciated.
