If you own a Suzuki Hayabusa of any year and you have modified your clutch in anyway, then pay close attention. You may have damaged your clutch slave unit and not know it. If you have added shims to your clutch springs, installed any number of aftermarket modified clutch hubs, baskets, springs and such, then you may have a cracked clutch slave unit due to the added exertion put upon that unit. Actually, I have seen some units only fractured and have hairline cracks and some others that were blatantly broken.
