I know grooves in the clutch basket cause slippage and premature clutch failure. Do grooves in the clutch hub have the same effect or can I get by with not replacing my clutch hub as well?
Grooves on the basket and hub cause the clutch to feel jerky. Without holding the clutch handle, it should still hold. The basket has a greater affect on this than the hub. You should be able to get away with just filing the hub as much as you can.
I already got a Hinson basket and a new hub through Jason on here is like $60. My old friction plates and steels weren't in that bad of shape. So I'm hoping I can just reuse the plates and hub I have and save putting a new hub and clutch plates in for at least a couple months.
