Re: 1970 RT-1 360
PULL OFF the clutch cover, go to hardware store and pick up 480 grit wet sandpaper(its black) take the friction plates and lay them flat on sandpaper, spray wd-40 on sandpaper also, move plates in a figure 8 pattern, this will remove any glaze on the plates and prevent slippage. you will also see if the plates are stuck together when the cover is off. you need to change that oil anyway. this was in dirt rider mag so i am not nutz and it does work.
When in doubt, GAS IT
