Servicing Your Honda 61
Engine Idle Speed
Refer to Safety Precautions on page 23.
Remember, idle speed adjustment is not a “cure-
all” for other problems in your engine’s PGM-FI
system. Adjusting the idle will not compensate
for a fault elsewhere.
The engine must be at normal operating
temperature for accurate idle speed adjustment.
When pushed in, the fast idle knob acts as the
idle adjust screw.
Turning it counterclockwise results in a
faster/higher idle speed.
Turning it clockwise results in a slower/lower
idle speed.
Idle Speed Adjustment
1. If the engine is cold, start it and warm it up 3
minutes. Then shut it off.
2. Connect a tachometer to the engine.
3. Shift the transmission into neutral. Start the
engine.
4. Keep the motorcycle in an upright position.
5. Adjust idle speed with the fast idle knob (1).
