THROTTLE AND CHOKE CABLE
ADJUSTMENTS
Idle Speed Gap / Throttle Free Play
Adjustment - VM Carburetors
1. Always set the idle speed when the engine is at
operating temperature.
2. Turn the idle speed adjustment screws on each
carburetor out at least 2 turns.
3. Reference the throttle gap drill bit size specification for
each engine. Insert the drill bit(s) under each of the
throttle slide cutaway(s).
4. Loosen lock nut(s) (on top of carburetor) and turn the
throttle cable adjuster in (clockwise) or out
(counterclockwise) until a slight drag can be felt on the
drill bit.
5. Secure the adjuster lock nut(s).
6. Slowly turn each idle speed screw inward until the tip
begins to touch the throttle slide. Remove the drill
bit(s).
7. Set the throttle lever free play by loosening both
carburetor adjuster lock nuts. Turn each adjuster out
equally until the throttle lever free play is set.
8. Secure the adjuster lock nuts.
NOTE: If the idle speed screw is adjusted inward and
the cable sleeve is not adjusted to take up the throttle
lever clearance, the engine may misfire or quit upon
initial throttle opening.
When adjusting throttle lever free play, always verify the
engine idle RPM does not increase when turning the
handle bar to the full-left or full-right positions.
After idle speed adjustments are made, the throttle lever
clearance and oil pump adjustment must be checked
and adjusted.
