For motorcycles not equipped with tachometers, the following
table may be used as a guide for estimating the engine RPM
in each gear based on the road speed.
PRE-RIDING CHECKLIST
Before riding or with each tank of gas, confirm that your
motorcycle is in good operating condition. The motorcycle
owner’s manual has specific information regarding this subject.
To insure safe, reliable engine operation:
1. Check oil level in oil tank.
2. Check for oil and fuel leaks.
STARTING AND WARM-UP
General:
1. Before starting engine, shift transmission into
neutral.
2. Never allow engine to exceed 2,500 RPM
immediately after cold start. Engine should run
slowly for 15 to 30 seconds. This allows engine to
warm up, and oil to reach all surfaces requiring
lubrication.
3. Idling with enrichment device lever in full-out position
for longer than 30 seconds is not recommended.
Lever may be set in intermediate position if engine
will not run smoothly with it all the way in.
4. Use oil of viscosity recommended for expected
ambient temperature range and type of operation.
Cool Engine:
1. Open petcock if it is manual type.
2. Pull enrichment device lever to raised position.
3. Twist throttle one or two times.
4. Close throttle.
5. Turn Key to IGNITION.
6. Turn Engine-Stop Switch to RUN.
7. Press Start Switch.
8. After engine starts, adjust enrichment lever
depending on ambient temperature:
a.
Below 70
°
F (21
°
C) - Push enrichment lever in
as engine warms. If idle becomes slow or rough,
pull lever up slightly. Enrichment lever should
be pushed in completely after not more than 60
seconds of operation.
b. 70
°
F (21
°
C) or Warmer - Push enrichment lever
completely in after 10 to 30 seconds of
operation.
Warm or Hot Engine:
1. Open petcock if it is manual type.
2. Pull enrichment lever to fully raised position.
3. Turn Key to IGNITION.
4. Turn Engine-Stop Switch to RUN.
5. Press Start Switch.
6. After engine starts, immediately push enrichment
lever all the way in.
JUMP STARTING
Jump start the motorcycle according to the motorcycle
owner’s manual.
CAUTION - To avoid damage to ignition system, start
engine using a 12 volt booster battery only. Confirm
that jumper cables are connected correctly before
attempting to start engine.
WARNING - Many motorcycle frames do not allow easy
access to battery terminals without touching jumper
cables to conductive surfaces which may cause sparks.
Batteries often emit explosive gas which sparks may
ignite. For this reason battery should be removed from
motorcycle for recharging.
GEAR CHANGE SPEEDS
For normal riding, the recommended acceleration shift points
to higher gears while accelerating are shown on the following
page. Note, for best fuel economy, use the smaller numbers
in each speed range.
For normal riding, the recommended shifting procedure to
lower gears while decelerating is:
1. Disengage clutch.
2. As motorcycle slows, shift into appropriate gear for
beginning next mode of operation.
