Well my clutch is starting to make noise and will have to be replaced sometime in the near future probably. Im gonna take this opertunity to replace the flywheel with a lighter one. They guy suggested the act. Does anyone here have the streetlite 12.5 lb and how do you like it? Its probably gonna go with a type r clutch if that matters at all. Oh yeah does 650 sound good to replace the clutch? add 30 to that if i go with the type r clutch. Any other suggestions for a flywheel would be helpful. Anyone know the stock weight of the flywheel?
