Default Yamaha exciter clutch sticking?

I have a red 1991 yamaha exciter, some times the clutch sticks sometimes it doesnt, Its so bad, sometimes in order to start it, I have to spray silicone on the primary sheave so it will spin enough to start up, then at idle, it will often "pull away" even when your not on the throttle, if you set the parking break the engine dies, the idle is set a 1500, I greased the slides on clutch, still no go?

Does anyone have any idea, my next idea is to run machine inside on stand and make sure both clutchs engage and disengage?

what is your belt deflection maybe it too tight. there should be about 1 inch of up/down movment. is it the right belt? when you say sticking is it down in the secondary /up in the primary?
wide open till you see god then brake

hesitation means devastation

Is it sticking or stuck? The bushings in the clutch weights wore through on my exciter allowing them to ride up and over the rollers essentially locking the clutch slightly engaged. cant go wrong by pullin er apart and takin a look while you clean it out. most of the time they are just full of belt shavings and dirt.
