MAINTENANCE WORK ON CHASSIS AND ENGINE »
Adjusting the throttle cables *
The throttle grip should always provide for a backlash of 3-5mm. Besides,
with the engine running, the idling speed must not change if you turn the
handlebar all the way to the left or right.
To adjust the throttle cables, dismount the seat and the tank together with
spoilers. Slide back the protection cover [9]. Loosen the counternut [10] and
turn the adjusting screw [11] accordingly. Turning the adjusting screw
counterclockwise will reduce the backlash, turning the adjusting screw clock-
wise will increase the backlash.
Tighten the counternut and check whether the throttle grip can be
actuated smoothly. Mount tank and seat.

Be sure not to pinch the throttle cables when mounting the tank. Afterwards,
check the throttle cables for easy action.
Cleaning the air filter *
The air filter must be cleaned prior to each race or whenever dust has accu-
mulated. To clean, lift the filter box cover [1]
(see illustration) and pull off towards the front.
Detach the bottom of the filter retaining bracket [2], tilt aside and remove
the throttle cap [3] and the air filter [4] and filter support [5] from the filter
box. The XC models do not have a throttle cap.
– Do not clean foam filter with fuel or petroleum since these damage the
foam. KTM recommends the products of the company Motorex for air fil-
ter maintenance (Bio Dirt Remover and Liquid Bio Power).
– Never start your motorcycle without any air filters. Otherwise, dust and
dirt may penetrate and cause damage and increased wear.
– Dust and dirt can accumulate and damage the engine if the air filter is
not mounted correctly.
Thoroughly wash the air filter in special cleaning fluid and allow it to dry well.
Only press out the filter, do not wring it out under any circumstances. Oil the
dry air filter with a high-grade filter oil. Also clean the air filter box. Check
the carburetor collar for damage and that it is filled correctly.
Mount the air filter on the filter support. Insert the air filter and filter support
in the throttle cap and mount them in the filter box, aligning in a central posi-
tion, and fix with the filter retaining bracket.
