Nr. 3. 210. 49 04/2002 IMPORTANT PLEASE READ THIS MANUAL CAREFULLY AND COMPLETELY BEFORE GOING ON YOUR FIRST RIDE. IT CONTAINS A GREAT DEAL OF INFORMATION AND ADVICE WHICH WILL HELP YOU USE AND HANDLE YOUR BIKE PROPERLY. IN YOUR OWN INTEREST, PLEASE PAY PARTICULAR ATTENTION TO NOTICES THAT ARE MARKED AS FOLLOWS: IGNORING THESE INSTRUCTIONS, CAN BE DANGEROUS TO LIFE AND LIMB. ! [. . . ] STANDARD SETTING: Unscrew the adjusting screw to the limit and then back 2 turns. 1 ENGLISH 28 2 1 Changing the spring preloading of the shock absorber The spring preload can be changed by turning the adjusting ring 2. For this purpose, you should dismount the shock absorber and clean it thoroughly. NOTE: ­ Before changing the spring preload note down the basic setting, e. g. how many threads are visible above the adjusting ring. ­ One rotation of the adjusting ring 2 changes the spring pretension by approximately 1. 75 mm (0. 07 in). Loosen the clamping screw 3 and use the hook wrench contained in the vehicle tool set to turn the adjusting ring as desired. Turning it counterclockwise will reduce the preload, turning it clockwise will increase the preload. After readjusting the clamping screw 3, tighten it to 8 Nm (6 ft. lb) 3 A ADJUSTMENT VALUES - SPRING PRELOAD A minimum preload . 10 mm (0. 4 in) Pivot bearing The pivot bearing 4 for PDS suspension struts at the swinging fork is Teflon-coated and must not be lubricated with either grease or other lubricants. Grease and other lubricants cause the Teflon coat to dissolve, whereby the bearing's lifecycle will be reduced dramatically. When cleaning your bike with a high-pressure cleaner, do not aim the highpressure spray directly at the pivot bearing. 4 Check chain tension A To check the chain tension, park the motorcycle. Press the chain upward at the end of the chain sliding component. The distance between the chain and the swing arm should be approx. In the course of this procedure, the upper chain portion A must be taut (see drawing). If necessary, correct the chain tension. WARNING ­ IF THE CHAIN TENSION IS TOO GREAT, PARTS WITHIN THE SECONDARY TRANSMISSION (CHAIN, CHAIN WHEELS AND REAR WHEEL BEARINGS) WILL BE SUBJECTED TO ­ TOO ­ UNNECESSARY STRESS, RESULTING IN PREMATURE WEAR AND EVEN CHAIN BREAKAGE. 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. 15 m m 29 Correct chain tension Loosen collar nut 1, loosen lock nuts 2, and turn right and left adjusting screws 3 equally far. Before tightening the collar nut, verify that the chain adjusters 4 are sitting close to the adjusting screws and that the rear wheel has been aligned with the front wheel. Tighten collar nut 1 to 80 Nm (60 ft. lb). WARNING ­ 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. [. . . ] ­ Check the motorcycle as before each start (see driving instructions) ­ Take a short, careful test ride first. NOTE: Before you put your motorcycle away for the winter, you should check all parts for their function and wear. Should any service jobs, repairs, or any refitting be necessary, you should have them carried out during the off-season (lower workload at mechanics' shops). This way, you can avoid the long waiting times at your shop at the beginning of the next biking season. ENGLISH ­ Before cleaning with water, plug the exhaust pipe to prevent water ingress. [. . . ]
