I read a post (I think on this forum) by someone who has replaced their clutch with an aftermarket. I'm thinking of replacing mine at the same time my engine is being replaced. Anyone with recomendations? Clutch recomendations would probably be based on the kind of driving we do. I would rate myself as 5 on a 1-10 aggressive riding scale but just can't turn down an invitation to show what the bike is capable of. Also, if an aftermarket clutch is put in, what effect would this have on the warranty?
