Another issue I'm curious about - I'd removed the transmission and replaced the main seal & "O" ring. The clutch was shot. An airhead friend came over and with his tools thought all the other components looks good. I lost track of the paint marks when putting the clutch back together - the diaphragm spring when in the way it came out but the compression & pressure plates between the clutch may not have gone in exactly the same way. I used a clutch alignment tool and it went together as I believe it should have.
The clutch works good - the only issue - I notice when taking off that the bike makes a squeal sound - sorta like a "urk" like the sound of a squeaky brake. Once I'm in motion the bike shifts & drives great.
The splines have fresh moly grease too. Bike didn't make the noise when I acquired her with a worn out clutch.
