Idle Speed

(Refer to the Safety Precautions on page 42.)
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

1. Adjust the fuel mixture by turning the pilot screw
(2) clockwise until you hear the engine miss or
decrease in speed, then counterclockwise until
the engine again misses or decreases in speed.
Set the pilot screw exactly between these two
extreme positions.
From a fully closed position, the correct setting
(between extremes of rich and lean) will be
approximately: 1-5/8.
2. If the idle speed changes after adjusting fuel
mixture, readjust the idle speed by turning the
throttle stop screw.
