here is my reason.. drag race and go thru more clutches in year than most do in time they own bike. in that i have tried every brand of clutches.. ebc, barnetts, all different steels, cryo, stock and such. some felt grabby, but none lasted as long as oem yamaha plates did. they had better feel, fit better, put less clutch residue into basket. all yamaha needs is stiffer springs to help clutches last longer. i have stacks of plates and steels from 00 and 04...all over my shop, trailer, every bench and table. some of aftermarkets are more expensive than yamaha, but dont last as long. so why spend more $$ for less? with 98-03, they need barnett SR3 spring conversion or run 2 stock diaphram springs to increase pressure. with sr3 run 3 street springs and 3 race springs. i couldnt run 6 race springs as i couldnt pull clutch in after few minutes of riding.. it was 2 stiff. im not big supporter of aftermarket stuff.. in my opinion it should be better than stock stuff... but in clutch department... there not up to speed.
