Slipping clutch

Which is?
My clutch is something Carpenter puts together using stock and Hayabusa parts, with Carpenter's springs. With 252 hp to the rear wheel, I've never had any problems with the clutch slipping. With a stock motor, you should be able to stop the slipping with just heavier springs.
 
Seems like a toss up between OEM or Barnett for springs and MTC basket and fibres thanks again
 
Barnett complete clutch kit did the trick for me. Stock springs turned out to be the problem. Fibers and rings were fine but replaced them anyhow.
 
@Hillbilly I hope you have it sorted. I waited too long on replacing mine and had a total clutch failure on the Freeway. Cost me an arm and a leg to have the dealer rectify it for me. That was at 58K miles...
