PW50 clutch spring mod problem help

[QUOTE="stalefish, post: 1096933, member: 71645"] I went through and checked it over, The holeshot springs I ordered for $20 were a larger diameter than stock. I'd say stock looks to be 7/16 and the holeshots are 9/16 and made of thicker wire. today I went to the hardware store and found some springs of the same length and wrap and diameter as stock just a bit stiffer. I took two screwdrivers and give them a little stretch to increase the length by maybe a couple mm. I installed these and instead of filling up with Yamalube4 10w30 I got some bell rae 75w tranny oil. It is actually thinner than the Yamalube4 even though it says 75w. It runs good. Takes a bit more throttle to go off the line than stock, but does not impede function, my son isnt racing the bike. Just needs some more go. And it solved my spinning back tire in idle problem as I posted earlier this month. When you give it throttle while riding it definitely has more kick. I spent $1.60 on these springs. I think I may market them :) [/QUOTE]
