[QUOTE="Constant Mesh, post: 837035, member: 615"] Don't see any need to clean the throttle valves unless the throttle grip becomes hard to turn or wants to stick in the closed position. In the photo shown above the buildup of soot on the edge of the valve should have no effect on air flow. The lower edge of the butterfly is the leading edge for the inrushing air. The edge appears quite smooth with no buildup. Since the valves don't close completely at idle they're not prone to stick in the idling position. Needless maintenance I wouldn't perform. [/QUOTE]
