I need help getting a good clutching set up I have done alot of searching and there is so much info out there its hard to come up with good results. My 01 SRX current set up has a yellow and blue primary spring with a bender 8mm shim. Which I was thinking of switching to a White-White-White spring. 8dn-20 weights but I have no idea put much weight is in them. How much should it weigh. The secondary is a bender 47/43 with a yami green spring wrapped @ 60. I ride mostly in the trails. What would you keep and what would you change?
