[. . . ] Turning in a clockwise direction will increase the damping, turning counterclockwise will decrease the damping. STANDARD ADJUSTMENT LOW-SPEED: ­ Turn adjusting screw [1] clockwise as far as it will go. ­ Turn 15 clicks in a counterclockwise direction. STANDARD ADJUSTMENT HIGH-SPEED: ­ Turn adjusting screw [2] (wrench size 17 mm) clockwise as far as it will go. The damping unit of the shock absorber is filled with high-compression nitrogen. Never try to take the shock absorber apart or to do anymaintenance work yourself. Never unscrew the black screw connection (24mm). MAINTENANCE WORK ON CHASSIS AND ENGINE » Rebound damping of shock absorber 40 By using the adjusting screw [1], the degree of damping of the rebound can be adjusted. Turn the knob in a clockwise direction to increase damping, turn it in a counterclockwise direction to reduce damping during rebounding. 1 STANDARD ADJUSTMENT: ­ Turn adjusting screw clockwise as far as it will go. The damping unit of the shock absorber is filled with high-compression nitrogen. Never try to take the shock absorber apart or to do any maintenance work yourself. Severe injuries could be the result. Breathing the fork legs 2 Breath the fork legs regularly (see Maintenance Schedule). To breath, place the motorcycle on the side stand and briefly remove the bleeder screws [2] to allow any overpressure to escape from the fork. Excessive pressure in the interior of the fork can cause leaks in the fork. If your fork is leaking, it is recommended to open the breather plugs before having the seals replaced. MAINTENANCE WORK ON CHASSIS AND ENGINE » Checking the chain tension A 41 Place the motorcycle on the side stand. The distance between the chain and the swing arm should be 7 mm (0. 3 in) when the upper part of the chain [A] is tensioned (see drawing). Correct the chain tension if necessary. 7 mm 4 3 ­ If chain tension is too great, parts within the secondary power transmission (chain, chain sprockets, transmission and rear wheel bearings) will be subjected to unnecessary stress, resulting in premature wear and even chain breakage. ­ Too much slack in the chain, on the other hand, can result in the chain jumping off the chain wheels. If this happens, the chain could also block the rear wheel or damage the engine. ­ In either case the operator is likely to lose control of the motorcycle. Correcting the chain tension 1 B 2 Loosen the collar nut [1], loosen the counternuts [2] and turn the left and right adjustment screws [3] the same distance. To make sure the rear wheel is aligned, the marks on the chain tensioners must be in the same position on the left and right in relation to the reference marks [B]. Before tightening the wheel spindle make sure the chain tensioner [4] rests against the adjustment screws and the rear wheel is aligned with the front wheel. If you don't happen to have a torque wrench at hand, make sure you have the tightening torque corrected by a KTM dealer as soon as possible. [. . . ] ­ clean motorcycle thoroughly and let it dry ­ treat engine, swing arm, and all other bare parts (except for brake discs) with a wax-based anti-corrosion agent. Keep anti-corrosion agent from getting into contact with the brake discs, for otherwise this will significantly reduce the braking power. After rides on salted roads, clean motorcycle thoroughly with cold water and let it dry well! STORAGE » 78 Should you desire to make a pause over a longer space of time, please observe the following instructions: ­ Drive the tank empty to be able to fill up with fresh fuel when starting the motorcycle up again. ­ Clean motorcycle thoroughly (see chapter: CLEANING) ­ Change engine oil and oil filter (old engine oil contains aggressive contaminations).
