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. ! [. . . ] The preload adjuster used in the SX models can easily be retrofitted for the telescopic forks of the MXC/EXC models. NOTE: WP precisely adjusts the spring pressure by inserting pretension spacers. Fluctuations in production are compensated with pretension spacers in various heights. This can cause the fork springs in the fork legs to have different degrees of pretension. Fork springs and pretension spacers should always stay together. 1418X725 1418X736 SPRING RATE 125 SX 250/300 MXC/EXC 4, 2 N/mm 4, 0 N/mm 3, 8 N/mm 60 65 70 75 80 85 90 RIDERS WEIGHT INCLUSIVE GEARS IN KILOGRAM 1418X735 125 EXC 200 SX/MXC/EXC 4, 0 N/mm 3, 8 N/mm Replacing fork springs If you weigh less than 70 kg or more than 80 kg, you should install the respective fork springs. The type number of the telescopic fork is embossed on the caps on the top of the telescopic fork. According to our experience, the damping rate of the compression stage can remain unchanged. The damping rate of the rebound stage can be reduced by a few clicks for a softer spring or increased by a few clicks for a harder spring. SPRING RATE 3, 6 N/mm 60 65 70 75 80 85 90 RIDERS WEIGHT INCLUSIVE GEARS IN KILOGRAM ENGLISH The precise riding sag of the telescopic fork cannot be determined for various reasons. Similar to the shock absorber, smaller deviations in your weight can be compensated by adjusting the spring preload. However, if your telescopic fork bumps frequently (hard end stop during compression), you should install harder fork springs to avoid damaging the telescopic fork and frame. Adjusting the spring preload on the fork (SX) The spring preload on the SX models can be adjusted (changed) by 10 mm by turning adjusting screw 1. Turning in a clockwise direction will increase the prestress, turning in a counterclockwise direction will decrease the prestress. Changing the spring preload will not affect the rebound damping adjustment. Generally, if the spring preload is higher, the rebound damping should also be set higher. 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. ­ 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. [. . . ] In this way the carburetor jets are prevented from becoming resin- clogged by the old fuel. Actuate kick-starter 10 times in order to distribute the oil onto the cylinder walls and mount the spark plug. The storage place should be dry and not be subjected to too big temperature fluctuations. Do not use non airtight materials as a possible humidity might not be able to escape and thereby cause corrosion. [. . . ]
