I think I will go with the HPD brown primary spring and s55 weights. Violet secondary spring set at 2-2 with a 40/36 helix. I tried 10-58s with the red/yellow primary and it seemed like the revs came up too slow on the top end but was good out of the hole. Tried red/yellow with the s55 weights and it seemed to over rev with a slower top end but was still good out of the hole. The red/yellow seems like it needs something between the s55 and the 10-58 weights to me (I could be wrong). I didn't try the brown spring with the 10-58 weights because I think that would be going in the wrong direction. Anyone else with the mods I have got any thoughts on what they like as far as clutch setup goes.

 

Try a Polaris red with your weights before you go to the brown.And set the helix at 1-1 if you dont need the hard back shift.
