MC500 Cold starting
1. Make sure the vehicle is on level ground and the
transmission is in NEUTRAL.
2. Turn the ignition switch to the "ON" position and wait 3
seconds as the fuel pump pressurizes the fuel injectors.
3. Shift transmission into NEUTRAL and pull-in and hold
in the clutch lever.
4. Carefully take up the throttle lever freeplay, then take up
1mm more.
1 mm throttle lever freeplay
5. Press and hold the engine start button for no more than
2 to 3 seconds at a time. If the engine "pops" or seems
to backfire you're holding the throttle open too much.
1mm is a very fine lever movement. Back the lever off,
wait briefly, and re-try.
6. When the engine fires, hold the throttle at a fast idle for
10 seconds or until a smooth idle is obtained.
7. Always wait for the engine to reach operating
temperature (70°C) before riding.
ATV MC1000 Cold Starting
1. Make sure the vehicle is on level ground and the
transmission is in NEUTRAL.
2. Turn the ignition switch to the "ON" position.
3. Switch the engine stop switch to "RUN."
4. Pull in the clutch lever.
5. Quickly, press the engine start button and release it.
6. WAIT 5 SECONDS. This 5 second wait is required to
activate the engine management circuits. During this
time the fuel pump turns on for three seconds to
pressurize the injectors. And, the Idle Air Control Valve
(IACV) moves into position opening the idle bypass
port. If you don't wait 5 seconds, insufficient fuel
pressure and incorrect idle air bypass positioning will
prevent the engine from starting.
7. After waiting 5 seconds, press and hold the engine start
button for no more than 2 to 3 seconds at a time.
8. When the engine starts, slowly release the clutch lever.
9. Allow the engine to idle until it reaches operating
temperature (70°C) before you begin riding.
