I've gone through the stock clutch on my 02 426. I'm looking for advice on a replacement clutch kit. Should I stay with the OEM or are aftermarket clutch kits better/worse? There are several kits out there to choose from and they vary quite a bit in price. I've done all the free mods and the exhaust cam is retarded to the YZF timing. Would a race clutch work better??? I'm not really worried about the price, I just want to make an educated purchase. Any advice would be greatly appreciated.
