Hey there guys, just wondering if this idea is feasible. I have a 350, and all I need out of a clutch kit is 500 stall springs. OK well since I have a 350, what if I put 400, 450, or maybe even 650 springs. Won't that be the same thing. I asked the parts guy at the nearest yamaha dealer, he said he didn't know. He just deals with parts numbers all day. What yall think I should order to start, 400 or 450?
