Idle Speed

(Refer to the Safety Precautions on page 39.)
The engine must be at normal operating temperature
for accurate idle speed adjustment. 10 minutes of
stop-and-go riding is sufficient.
Do not attempt to compensate for faults in other
systems by adjusting idle speed. See your Honda
dealer for regularly scheduled carburetor adjustments.
1. Warm up the engine and hold the motorcycle
upright.
2. Connect a tachometer to the engine.
3. Adjust idle speed with the throttle stop screw (1).

Idle Mixture

screw (2) clockwise
engine miss or decrease in speed, then
counterclockwise until the engine again misses
or decreases in speed. Set the pilot screw

From a fully closed position, the correct setting
(between extremes of rich and lean) will be
approximately: 2.
2. If the idle speed changes after adjusting fuel
mixture, readjust the idle speed by turning the
