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 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
To check the gear oil, warm up the engine to operating temperature with a
low load and place the motorcycle on an even surface. Remove the oil drain
plug [2] and allow the gear oil to drain into a vessel. Clean the sealing area,
mount the oil drain plug and gasket and tighten to 15 Nm.
Remove the oil filler screw [4] and add 0.5 liters of gear oil (e.g. Motorex
Topspeed 4T 15W50). Mount the oil filler screw and check the engine for
leaks.
If the gear oil is still clean you can continue to use it up to your next service.
– too little oil or a poor oil quality will cause the transmission to wear pre-
maturely. Only use brand-name oils.
– due to a change in the fluid capacities the inspection screw [3] can no
longer be used.
Engines and engine oil are extremely hot at operating temperatures - be care-
ful not to burn yourself.
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 [2] 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 0.5 l gear oil (e.g. Motorex Topspeed 4T
15W50). Mount the filler plug and check the engine for leaks.
