    You need a stiffer or heavier diaphragm spring for your pressure plate to hold the extra force.

    Our bikes were designed to put down what 80-90 hp / 90-95tq to the ground? When you increase the output 35-40% on a clutch design that is not all that different from what you find in a 883 to 1200cc bike you will break something. Usually at the weakest point, which on our bikes is the teeth on the lifter rack assembly.

    The Barnett diaphragm spring is rated to be at least 25% stronger than the “green” OEM spring. That is enough to lead to a failure of the lifter rack teeth more often than not.

    The easy fixes are to use the older Victory lifter rack, or modify a Indian lifter rack to work in your Victory.

    The cheapest is to not make any upgrade to the power pack at all. Ain’t NOBODY got time for that!

    There it is. Add a stronger spring, the rack may break...

    I’ve heard Rylan and others say that a stock victory clutch can handle 115/115 (or there abouts ) all day long. I’ve never had issue with holding that power.

    Some people go through a clutch in 10k miles while others can go 100k...

    Have definitely witnessed very poor clutch operation from “seasoned riders”. Was quite surprising to me. One in particular I literally said to myself (inside my helmet while we are riding together)…”you’ve been riding for how many years and ride the clutch like it’s a piece of taffy?”

    I felt sorry for the bike/clutch.
