Has anyone figured out which helix to use for a 95 zr 580 efi with a roller secondary? I converted from the old style clutch and can't quite get what I need. I either lack top end or max rpm when messing with my 53 degree helix yellow spring. I'm thinking of going back to the button style and selling this thing, I hate trying to understand clutching :withstupid:
