5.5 - Engine Idle Speed Adjustment

The idle setting of the carburetor has a big influence on the vehicle’s starting behavior, on stable idling and on the vehicles response when the throttle is opened.

An engine with a correctly set idle speed is easier to start than an engine with the idle speed set incorrectly.

The idle speed is adjusted with the idle speed adjusting screw.

 

  1. If the engine is cold, start it up and warm it up for 3-4 minutes. Then shut it off.
  2. Connect a tachometer to the engine.
  3. Shift the transmission into neutral. Start the engine.
  4. Remember to keep the motorcycle in an upright position.
  5. Adjust the idle speed with the idle adjusting screw or knob
  6. Idle Speed: 1,500 – 1,800 ± 100 RPM
  7. NEVER ADJUST THE AIR/FUEL MIXTURE SCREW IT HAS BEEN SET AT THE FACTORY AND SHOULD ONLY BE ADJUSTED BY AN AUTHORIZED AJ1 DEALER.
