Have you removed the throttle tube yet? It's easy--two screws out of the throttle case assembly. See if there is crud built up between the tube and the bar, and look closely to see if the tube is warped. If it is straight but dirty, clean and maybe lube with a dry lube...powdered graphite for example...nothing that will hold grit. If the tube is warped, junk it.
When you reassemble, adjust the throttle cables according to the owner's manual. A too-tight return cable results in a sluggish return.
