If it's slipping and it's the std clutch plates often that's due to poor or the wrong oil being used, it could also be a cheap replacement clutch plates having been fitted and poor or the wrong oil.
Std Yamaha complete clutch plate set for an FZS1000 is about £350 odd last time I looked, or you buy the plates separately between £15 - 25 aprrox each, EBC it's £60 odd for just friction plates. If a clutch is in need or replacement plates it will not only be the friction plates that need changing. The drive plates can and often do warp, new fraction plates can and do take up some of that clearance but not for long or not at all. The clutch starts slipping, owners then fit HD springs which flatten the warped plates out, end result heavy clutch action, this can also place undue loads on the release mechanism, this in turn cracks/bends or knackers the bearing in that mechanism.
