I have a 98' PS efi 600. I ride at 5-10,000ft. I recently put a set of v-force and a D&D pipe and chip on it. The local shops haven't set very many of these up but I think I have enough info to get started - Yellow white up front yellow in back and 48 to 48.5 wieghts , 51 helix. Can anyone give me additional info on like setups especially the progressive or multi angle helixes. I really don't understand their benifits. thanks ,craig

I use a 52/48 helix with a PSI green spring and 49.5 weights with yellow/white spring on wifes 98 600ps EFI and seems to work well. Hope this helps.

Re: Helixes???

multi angle helixes usually have a steeper initial angle to speed up the shift or to improve acceleration and a smaller angle to still allow good clutch backshift for throttle response. If you are using a roller secondary you probably won't need a multi angle because of the smoother shift due to reduced friction. You also may not need a multi-angle if you are using some of the new adjustable primary weights set up to load the engine properly and shift straight.
