STARTING YOUR MOTORCYCLE
The following starting procedures are general guidelines for starting your motorcycle.
COLD STARTING
Cold starts occur when the engine has not been running for a significant period of time and the engine temperature is
approximately the same as the ambient (outside) temperature. Follow the instructions below to start a cold engine:
1. Place the transmission in Neutral.
2. Pull up all the way on the fuel enrichener lever, located above the air cleaner (ON position).
3. Turn the fuel valve to the “on” position (main fuel) and wait 30 seconds for the carburetor bowl to fill with fuel.
4. Twist the throttle grip once or twice only ("pumping" the throttle).
5. Turn the ignition key to the Start position. (The green indicator on the instrument panel assembly should come
on to verify that the transmission is in Neutral)
6. Pull in the clutch lever to disengage the clutch.
7. Press the OFF/RUN switch in the RUN Position.
8. Push the starter switch only once to engage the electric starter for no more than a few seconds.
9. If the engine does not start, repeat the above procedure.
10. After the engine starts, wait until it is warm before pushing the fuel enrichener lever back down to the OFF
position (pushed downward toward the air cleaner).
This process will take approximately one minute.
CAUTION: DO NOT ATTEMPT TO START YOUR MOTORCYCLE IN EXTREMELY COLD TEMPERATURES. FOR
EASIER STARTS IN TEMPERATURES BELOW 50 DEGREES, USE 10W40 OIL FOR AIR COOLED V-TWIN
MOTORCYCLES. DOING SO MAY DAMAGE THE ENGINE. IN EXTREME WEATHER CONDITIONS, THE PISTON
RINGS MAY SEIZE TO THE CYLINDER WALLS, RESULTING IN ENGINE FAILURE.
HOT STARTING
When the engine has recently been run and is still warm, or when it is very warm outside, the engine will not require
much fuel to start. It is not necessary to use the fuel enrichener lever or to "pump" the throttle when the engine is
warm; doing so will flood the engine and cause extreme difficulty in starting your motorcycle. To start a hot engine,
follow the instructions below:
1. Turn the fuel valve ("petcock") to the ON position and wait 30 seconds for the carburetor bowl to fill with fuel.
2. Turn the ignition key to the START position (the GREEN indicator on the instrument panel assembly should
come on, indicating that the transmission is in NEUTRAL).
3. Place the OFF/RUN switch in the RUN position.
4. Pull in clutch lever to disengage the clutch.
5. Push the starter switch only once to engage the electric starter.
If the engine floods, hold the throttle wide open (twisted fully counter-clockwise) and repeat the above procedure. The
engine will eventually clear the flooded condition and begin to run.
CAUTION: DO NOT RUN THE STARTER MOTOR FOR MORE THAN THREE TO FIVE SECONDS AT A TIME.
ALLOW 30 SECONDS BETWEEN STARTING ATTEMPTS TO ALLOW THE STARTER MOTOR TIME TO COOL
DOWN.
