Default 1979 FXS Clutch ?????

First post I have early 1979 FXS Went to Quaker Steak the other night and stopped at a light and my clutch started lunging or whatever. I am running a belt drive primary with Barrnet 5 spring clutches. Thought maybe the cable stretched. Anyway just got into it cable is good tried adjusting and same thing. Took of the primary cover and pulled the clutch in a noticed the pressure plate will start to disengage then the whole clutch shell, hub and all will move out with it. Any idea what would cause this?

Check and make sure the clutch hub nut hasn't backed off (Left hand threads). You can take a look at everthing if that isn't the problem while
you have it that far torn down.

Good luck.

Definately sounds like the hub nut is loose. Check to see if the key is still in place when you have it down.

the belt drive needs to have the hub bearings lubed from time to time-- what you described is EXACTLY what happens when they get dry -- the old grease dries out and it locks the bearing to hub -- ya also need the clutch tamer to keep that shell from wobbeling -- myself i use the long bearings -- and the tamer -- i can put the bike in gear and rarely hear that "bang" and i can take it out of gear at a light real easy -- i run the kevlar plates that have the grooves in them and i NEVER oil them like they suggest -- ruins them..

i also found that when the hub nut is off i put a green A/C "O" ring on the clutch shaft then when the hub nut is on i put another "O" ring on the shaft before i install the plates/steels/pressure plate -- make sure your outer primary is vented -- if not your gonna toast that belt --
