Now off to clutching,

Primary Spring: Pink-Green-Pink
Rollers: Stock
Weights: 60Y
Heel: Tungsten & 4 washer
Mid: Empty
Tip: Empty
Secondary Spring: Silver
Helix: Ulmer Racing "K"


This is what i have but i am way off. It hits the hard revlimter about 3-4 times every time and will hit it if rolling 20-30mph too!! But my top rpms are WAY to low right now 8350 or so. So if i add more weight to the heel and mid hole i will hurt that even more.... Any input would help, i could grind some weight off the back side of the tip of the weights i do have a scale.

Thank you Skydog
 
I do have a heavy hitter set base weight of 62.7 with TONS of washers and tunning weights. Should i try them? Or is the profile of the 60Y STM way better?

Thank you Skydog
 
You could go to a lower finish angle cam (driven clutch) to get the tunability on top and then add heel weight to get it off the limiter down low. Talk to Allan Ulmer would be your best bet.
