    Bully 3 disc

    Wanting to engage the clutch at 3350-3750 stall... on a 3 disc bully...

    Is it better to use stiffer springs and more weight or use weaker springs and less weight?
    Right now it has roller levers, red springs and a bolt in every space outer position...

    It will be used on a smaller displacement motor with low torque and high rpm..

    Thx

    ^ Exactly.

    Weight bolts in outers with springs @ .240" should get you close to the upper end of the rpm engagement that you want.

    I would prefer to add some bolts to the inners as well, and get your spring heights down around .210" or so to be in the meat of the rpm band that you mentioned.
