Adjust idling speed *
1
Use the adjusting screw
to adjust the basic position of the throttle valve
and, thus, the idle speed.Turning in clockwise direction will increase the
idling speed, turning in counterclockwise direction will reduce the idling
speed. Normal idling speed 1400 - 1500 rpm.
Draining of float chamber of the carburetor
Following every wet-cleaning procedure, the float chamber of the carbure-
tor should be drained in order to remove any water that may have penetra-
ted into it. Water in the float chamber leads to engine malfunction.
Wait until the engine is cold before commencing to perform the worksteps
indicated below.
Close the fuel tap.
2
Put the end of the hose
that leads downward behind the engine into an
appropriate container.
3
Open the drain plug
, turning it counterclockwise a few times, and let the
fuel drain from the float chamber.
Then tighten the drain plug and open the fuel tap.

Engine oil
Automobile engine oil used to be used for four-stroke motorcycles before
there were separate motorcycle specifications. Different technical develop-
ments made it necessary to have a separate specification for four-stroke
motorcycles - the JASO T903 MA standard. Whereas car engines require
long changing intervals, motorcycle engines require a higher power output
at higher speeds. Most motorcycle engines also use the same oil to lubricate
the transmission and the clutch. The JASO MA standard responds to these
special requirements.
Only use fully synthetic engine oils that meet the JASO MA quality require-
ments (see information on the can).
KTM recommends Motorex Power Synt 4T in the 10W/50 viscosity (for
temperatures over 0°C, 32°F) or 5W/40 (for temperatures under 0°C,
32°F).
Checking the engine oil level
The engine oil level can be checked when the engine is cold or warm.
To check, place the motorcycle in an upright position on a level surface
(center stand).
If the engine is cold, the oil level should be visible at the lower edge
the inspection glass.
If the engine is warm, the oil level should be visible at the upper edge
the inspection glass.
Add engine oil if necessary.
