Idle speed way too high
During my last time out with the bike (2002 VN750, 22,000 miles) -- just a short trip after a flawless 1700 mile journey -- when I pulled the clutch to come to a stop, the engine revved up to about 3000 rpm even though I had released the throttle. It continues to idle at about that speed -- turning the idle speed knob makes little difference. The throttle mechanism appears to be working correctly. My first thought is something is stuck in the carburetor but I thought I'd ask you all what else I should consider before tearing into things.

One of my choke plungers started to get sticky, but it was nothing a little WD40 didn't solve.

Visually check to make sure they're closing when you back off the choke.

Thanks for the info everyone. The plunger was not going down when the choke was pushed back. WD40 and a little pressure got it down and it is moving correctly and idling properly now. Is there some reason this would occur that needs more attention than I have given?

Easy, free fix. The best kind.

No...just needs to be cleaned now and then. A clean machine is a happy machine.
