MAINTENANCE WORK ON CHASSIS AND ENGINE
»
Draining the float chamber of the carburetor
Following every wet-cleaning procedure, the float chamber of the carburetor
should be drained in order to remove any water that may have penetrated into
it. Water in the float chamber leads to engine malfunction.
Make sure you do this while the engine is cold. Close the fuel tap and place
a cloth under the carburetor which is capable of absorbing the leaking fuel.
Unscrew the plug [1] and clean it with compressed air. Then, mount the plug
together with the gasket and tighten it to 4 Nm, open fuel tap, and check the
float chamber for leaks.
Fuel is easily flammable and toxic. When handling fuel, be sure to exercise
the utmost caution. Never perform any work on the fuel system near of open
flames or burning cigarettes. Always allow the engine to cool off first.
Immediately clean up any fuel which may have been spilled. Materials satu-
rated with fuel are also easily flammable. In case you ingested fuel or fuel
splashed into your eyes, consult a doctor immediately.
Dispose of the fuel properly!
Checking gear oil level
An inspection glass [2] on the left side of the engine allows easy checking of
the gear oil level.
Warm up the engine, then turn it off and wait two minutes until the oil has
flown back into the gearbox case.
Park the motorcycle straight on a horizontal surface and check the oil level.
The oil level must not drop below the „MIN“ mark of the inspection glass.
Note: If the motorcycle is not parked properly for the oil level inspection it
will not be possible to achieve a reliable result.
If necessary add gear oil 20W30 (e.g. Motorex Top Speed 4T 15W50).
Not enough oil or a poor oil quality lead to premature wear of the
transmission. Therefore, use only high-quality oils (e.g. Motorex Top Speed
4T 15W50).
Changing gear oil *
Before changing the gear oil warm up the engine and park the motorcycle on
a horizontal surface. Remove the oil drain plug [3] and drain the used oil into
an appropriate container. Clean the sealing surface. Mount the oil drain plug
together with its gasket and tighten to 15 Nm.
Remove the filler plug [4] and add 0.30 l gear oil 20W30 (e.g. Motorex Top
Speed 4T 15W50). Mount the filler plug and check the engine for leaks.
Not enough oil or a poor oil quality lead to premature wear of the transmis-
sion. Therefore, use only high-quality oils (e.g. Motorex Top Speed 4T 15W50).
