cause a deep discharge and damage to the battery.

Running-in procedure for the engine
¢
Attention: Pay attention to safety advice of the kart manufacturer.
To ensure that components have the longest possible lifespan, the engine must undergo a defined
running-in period at first operation or after a repair of the crankshaft or displacement parts.
¿
Note:
Cover the radiator with the mounted windshield to reach the operating temperature
earlier.
Observe the following issues:
P
Use a long gear ratio (standard or higher).
P
Use two sizes bigger main jet size based on altitude and temperature (see section
4.1.)
P
For the first 10 liters of fuel use a mixing ratio of 1:33 (= 3% or 0.3 liter oil per 10
liters fuel).
P
Make sure that the coolant temperature reaches 35 °C (95 °F).
P
Run the kart for 15 minutes at continuously changing load and engine speed
fluctuation up to maximum rotational speed. Rotational speed for max. 2 seconds!
P
Afterwards reduce the main jet size step by step until standard size is reached.
After this running-in procedure, the full power of the engine may be used.
¢
Attention: Use only fully synthetic two-stroke oil. BRP-Rotax recommends the use of XPS
Kart-Tec oil.
¢
Attention: The engine may never be operated without load. Is it operated without load (i.e. on
the trolley), rpm over 13.800 1/min are possible, which shortens the lifetime of
components (conrod, big end bearing etc.).
