6- If the engine is cold, lift the choke lever on the carburettor.
WARNING! Lower the starter lever again as soon as the
engine starts to warm up.
7- Leave the throttle closed. Pivot the kick-start lever
outwards and push energetically downwards with your
foot to start the engine.
8- Return the kick-start lever to its rest position. Leave the
engine idle for a few minutes to warm it up.
9- Switch the engine off and remove the radiator filler cap.
Check the level of coolant inside and top up as necessary.
10- Screw the radiator filler cap back on tightly. The
motorcycle is now ready for riding.
WARNING! Risk of burns! Only check the coolant level
with the engine cold and switched off.
NOTE. Motocross competition rules forbid the use of coolant
other than water.
WARNING! Never open the throttle abruptly. The
motorcycle could jump forwards, causing you to loose control.
WARNING! Check that the engine stop button stops the
engine effectively before you begin riding the motorcycle.
3. RUNNING IN
1- Run your new motorcycle in as instructed below to ensure
that the engine and transmission bed in correctly and to
ensure continuous reliability in future.
CAUTION! The first time you ride your new motorcycle,
ride for about two hours at low engine speeds to ensure that
it runs in correctly. Also respect the following precautions.
2- Once the engine starts, leave it idle until it warms up to
normal temperature. If you switch the engine off for a
short time, wait for it to cool down completely before you
re-start it.
3- During the running in period, always ride at constant
speed. AVOID RAPID ACCELERATION.
4- Even when riding at low engine speeds, avoid extended
difficult sections of road or track that could cause the
engine to become very hot.
5- Once you have run in your motorcycle following all these
instructions, take it to a Polini Motori dealer for its
post-running-in service. Apart from a change of spark
plug and engine oil, this service also includes the
disassembly of the cylinder to check on the condition of
the spark plug, cylinder head, piston and cylinder.
The service also includes the replacement of the spark
plug and of the transmission oil.

CAUTION! Scored pistons can lead to a drop in
performance and to rapid deterioration of the cylinder.
The nature of the carbon deposits that form on the cylinder
head, spark plug and exhaust port gives important
information about the fuel mixture burning in your engine.
Remember that mixtures that contain too much oil do not
extend the life of your engine.
4. SERVICING: INTERVALS AND OPERATIONS
The servicing described below is intended to keep your
motorcycle in peak condition. It consists of tasks that should

Once the seat is firmly in position, turn the seat lock 180
degrees clockwise to lock the seat in place.
4.2 REMOVING AND CLEANING THE AIR FILTER
