I have to baseline the clutch on the Banshee, my boys don't believe in doing that. The 1st thing is to measure the spring installed height. Then measure the pressure, if I remember right, it's around 100 lbs. total. Then I have to weigh the lock-up arms. We usually stagger the weight with 3 arms the same & the other 3 heavier or lighter depending on what we are trying to do.
The clutch tuning is critical on these engines with peaky hp & torque numbers. Plus, we run a 1.94 final gear ratio, but that will probably change to something around 2.00 ratio.
These things are really hard to get off the starting line without bogging. Lots of rpm, clutch slip & delay the lock-up arms about 10'-15' out. This is with a single stage lock-up. We also have a multi-stage lock-up that delays the lock-up arms further out.
Clutch tuning is one of my most favorite things about this quad, that I enjoy.
