STARTING THE ENGINE
General
The engine should be allowed to run slowly for 15-30 seconds. T his will allow the engine to warm up and let oil reach all surfaces needing lubrication. Failure to comply can result in engine damage. (00563b)
Do not roll the throttle before starting. Rolling the throttle before starting the motorcycle is unnecessary.
Starting
Shift transmission to neutral before starting the engine to prevent accidental movement, which could result in death or serious injury. (00044a)
- Turn the ignition/headlamp key switch to the IGNITION position. Do not roll the throttle.
NOTE The engine lamp will light for approximately 4 seconds and you will hear the fuel pump purr for approximately 2 seconds as it operates to fill the fuel lines with gasoline. - See Figure 42. Turn the off/run switch to the RUN position.
- Squeeze the clutch lever in against the handgrip.
NOTE To activate the starting system, the clutch interlock circuitry requires the clutch be disengaged, the clutch lever pulled in against left handgrip, and/or the transmission be shifted to the neutral position (green neutral lamp lit). - Press the starter button to start the motorcycle.
- Release the parking brake before riding the motorcycle. See CONTROLS AND INDICATORS, Reverse Operation.
NOTE If the fuel tank becomes completely dry, it may take a few seconds longer to start the motorcycle after filling the tank. It will not be necessary to take any extraordinary measures before starting the motorcycle.
Automatic Compression Release (ACR)
The engine should be allowed to run slowly for 15-30 seconds. This will allow the engine to warm up and let oil reach all surfaces needing lubrication. Failure to comply can result in engine damage. (00563b)
The vehicle is equipped with an Automatic Compression Release (ACR). During starting, a small auxiliary valve in the cylinder head is opened automatically by the ECM. The open valve releases the air compressed in the cylinder heads and allows the starter motor to turn the high compression engine over a faster rate to aid starting.
After starting and during normal operation, the ACR valves remain closed.
