Oil additive for wet cltch

[firefly]

I know many feel these products a snake oil but I've been using it on my other bike & it makes shifting much smoother & acceleration very strong, one can is enough for two oil changes & does not cause clutch slipping at all.

My Amsoil full synthetic makes my clutch feel better than any other oil I've tried and liked (Repsol, Honda HP4, Castrol full synthetic, Royal Purple, etc.)

Feels like I used an additive, but it's just good oil!
