Well I saw ESFR pro xr rider post about picking up some helixs and springs at the Big East show. I figured I should do the same. But I need some suggestions on my sled, Carl's is building me a 660 right now and I haven't gotten any setups from them yet. I need some clutching and gearing setups, I have a Pro XR 660 with SLP twins, 136" 1.25 Ripsaw. I ride mostly trails and do some of trail when I can. I want it setup to run corner to corner and still have alittle top end left.
