COLD START (ALL 250Fi - ALL 450Fi)
Cold start is the condition in which the coolant temperature is below 35°C.
As it works by injection, these models are not equipped with a fuel tap.
1. Retract the side stand (page 17)
2. Shift into neutral gear (page 17)
3. Press the choke lever (page 19) corresponding to the model of your
motorcycle all the way down and keep it pressed.
4. With the throttle fully closed, use the kick starter (page 17) or, in models
with E.S., the starter (EN/SMR/SMM page 14) or the start engine button
(MXE.S./SMXE.S. page 15).
5. Warm up the engine by accelerating slightly and, after about 1 minute,
release the lever. Use the adjustment knob if the engine has a low and
irregular idle speed (page 20). The idle speed must be kept constant
between 2500 and 2800 rpm for 250cc engines and 2200 and 2500 for
450cc engines. This facilitates subsequent starts.
WARNING
ON MODELS WITHOUT E.S., EVERY TIME YOU WANT TO START THE ENGINE, USE
THE KICK STARTER 1-2 TIMES, PUSHING THE PEDAL ALL THE WAY DOWN. DO
NOT USE THE PEDAL REPEATEDLY AND/OR PUSH IT DOWN PARTIALLY. USING
THE PEDAL ON THESE MODELS (INJECTION WITHOUT BATTERY) CAUSES THE
SAME FLOODING EFFECT THAT OCCURS WHEN THE THROTTLE IS OPENED ON
MODELS WITH CARBURETTOR.
COLD START (450F SMR/SMM - ALL 530F)
Cold start is the condition in which the coolant temperature is below 35°C.
1. Open the fuel tap (page 18).
2. Retract the side stand (page 17)
3. Shift into neutral gear (page 17)
4. Activate the cold start knob (page 19)
5. With the throttle fully closed, use the kick starter (page 17) or, in models
with E.S., the starter (EN/SMR/SMM page 14) or the start engine button
(MXE.S./SMXE.S. page 15).
6. Warm up the engine by accelerating gently and after about 30 seconds
disengage the cold start knob. Use the adjustment knob if the engine
has a low and irregular idle speed (page 20). The idle speed must be kept
constant between 2200 and 2500 for 450/530cc engines. This facilitates
subsequent starts.
- ALWAYS WEAR STRONG MOTORCYCLE BOOTS TO START THE ENGINE WITH
THE KICK STARTER TO PREVENT INJURIES. YOU COULD SLIP OFF THE PEDAL
OR THE ENGINE COULD KICK BACK AND MAKE YOU HIT YOUR FOOT FORCE-
FULLY.
- ALWAYS PUSH THE KICK STARTER ALL THE WAY DOWN VIGOROUSLY WITHOUT
ACCELERATING. KICK-STARTING WITH LITTLE FORCE OR WITH THE THROTTLE
OPEN INCREASES THE RISK OF ENGINE KICKBACK.
- DO NOT START THE ENGINE IN A CLOSED SPACE AND NEVER LEAVE IT RUN-
NING IN SUCH SPACES. EXHAUST GASES ARE POISONOUS AND MAY LEAD
TO LOSS OF CONSCIOUSNESS AND DEATH. WHEN THE ENGINE IS RUNNING,
ALWAYS MAKE SURE THAT THERE IS SUFFICIENT VENTILATION.
- ALWAYS MAKE SURE THAT THE GEAR IS IN NEUTRAL BEFORE STARTING
THE ENGINE. IF A GEAR IS ENGAGED WHEN STARTING THE ENGINE, THE
MOTORCYCLE WILL JUMP FORWARD AND MAY HARM YOU OR DAMAGE THE
MOTORCYCLE.
DANGER
WARNING
- ACTIVATE THE STARTER MOTOR FOR A MAXIMUM OF 5 SEC-
ONDS AT A TIME. WAIT ANOTHER 5 SECONDS BEFORE TRYING
AGAIN.
- DO NOT REV THE ENGINE WHILE IT IS STILL COLD. THIS COULD
CAUSE DAMAGE TO THE ENGINE. ALWAYS WARM THE ENGINE
UP IN NEUTRAL OR DO SO BY DRIVING AT A LOW RPM.
