I know there's a paper on tech area with yamaha number and specs for primary clutch spring but it stops at 30 spring preload and doesn't have all the spring. Would anyone have 30 and up to 55 or pass that? maybe the complete yamaha spring listing
 

PT#90501-580A2 BLU-BROWN-BLU
50........ 2.0.......... 116.......... 98.4............ 5.8
preload, spring rate, total force, free length, wire diameter

do you need more info or are you looking for a particular spring, if you need higher pre loads for a V4 with a short cover, you need to go to old Reichard springs, we used to use those and arctic springs back in the 750 days
 
Well what spring do you need I have a hundred, just tell me what you you need I have a spring tester and you just measure them
