3.5 ENGINE RUNNING-IN
The running-in of the engine must be performed following a few fundamental rules:
1.
Adjust the carburetion. Start with an adjustment on the rich side.
2. Warm the engine gradually for about 5 minutes at half throttle, making some laps at
low speed, gently closing and opening the carb. throttle (if a tachometer is installed
never exceed 11.000 ÷ 12.000 RPM). Never keep the same RPM for a long time.
3. Increase the speed for 5 minutes at ¾ throttle opening.
Never keep the same RPM for a long time.
4. Increase the speed for 5 minutes, at max. speed on the twisty parts of the circuit and
making the engine rich at half straight (cover with the hand for an instant the holes
on the inlet silencer keeping the throttle wide open).
WARNING:
O
nce the running-in is over and the engine is cold, check the torque of the exhaust
header nuts as, during the running-in, the nuts tend to become loose (refer to the
attached table).
3.6 RPM LIMITATION
The electronic box incorporates an RPM limiter which prevents the engine from
exceeding 14.000, 15.500 or 16.000 RPM, depending on the engine versions.
This limit cannot be exceeded otherwise the engine could be damaged by the extremely
high RPM.
WARNING:
Do not keep the engine for a long time at the RPM at which the limiter is functioning. This
would cause malfunctions on the induction and damage the reed valve.
When choosing the sprocket ratio always refer to a maximum limit which has to be
equal to the engine version max rotation limit (
i.e.
14.000, 15.500 or 16.000 RPM), so
that the incorporated limiter is not switched on continuously when the engine is running.
3.7 INLET SILENCER
Make sure that the inlet holes on the filter are towards the upper side and that they are
not plugged. Make sure that the clamp on the carburetor is not loosen and that the filter
is well fastened to the chassis.
Regularly clean the inside from oil deposits. If necessary remove the rubber manifold
with filter and clean it with gasoline or solvent.
