My CR5 clutch basket was severly notched. This caused a couple symptoms.
#1, the clutch would not fully disengage. If I was in first gear with the clutch pulled in the bike would creep hard.
#2, the clutch lever was harder to pull in that it used to be. Probably wouldn't make much of a difference on a vmax since its a hydraulic clutch but definitely noticeable with a cable type clutch.
#3, rougher shifting, harder to find neutral
I didn't feel like spending $$ on a basket and hub so I just removed the basket and filed the edges smooth. It took A LOT of filing since the notches in the basket were severe. Took very minimal dressing with a fine file on the hub. The fibers were fine and they still looked new (on the "fingers" that engage the basket)
Took me about an hour to file the basket. I put it all back together and my clutch felt brand new. Super easy to pull in, no creep when in gear, easy to find neutral, smoother shifts, etc.... Bad part about notching is that it creates more clearance for the plates to shift fore and aft in the basket and I would imagine it will notch even quicker than it did the first time.
Notching is pretty common on those bikes. I've heard of guys getting the OEM baskets machined and installing stainless inserts in the grooves where the plates contact it. Some of the aftermarket companies (Barnett)actually make a billet aluminum basket with stainless inserts.
