[. . . ] Disassemble the front wheel, remove screw [1] from the brake caliper and unscrew holding clamp. Measure the projection of the fork legs at the upper fork stabilizer and make a note of the measurement. Loosen the clamping screws [2] on the fork stabilizers and pull the fork legs down out of the fork stabilizers. ­ DO NOT OPERATE THE HAND BRAKE WHEN THE FRONT WHEEL HAS BEEN DISMOUNTED. ­ MAKE SURE THE BRAKE DISC IS ALWAYS ON TOP WHEN YOU LAY DOWN THE WHEEL, OTHERWISE THE BRAKE DISC CAN BE DAMAGED. 1 1 2 2 4 5 Thoroughly clean all parts and check for wear. Generously lubricate seals and springs and reassemble the telescopic fork. Insert fork legs in the fork stabilizers (projection as previously noted) and tighten clamping screws to 20 Nm (top) and 15 Nm (bottom). Mount front wheel (see chapter: mounting the front wheel). THE SCREWS [1] MUST BE SECURED WITH LOCTITE 243. Changing the telescopic fork oil * Remove front wheel and fork legs (see above). ­ It is very important to keep the brake disk free from oil and fatty matters. ­ After working on the brake system, always operate the hand brake lever to apply the brake shoes to the brake disk and have a point of pressure. A Pour 170 cm3 SAE 7. 5 fork oil into each fork tube. Adjust the air-chamber length [A] to 110 mm (4. 5 in) by extracting or adding fork oil. Mount the fork legs, front wheel and brake caliper (see above). ENGLISH 19 3 Clamp the fork leg into a vise (use protective jaws) and remove the plugs [3]. Remove screws [4] at the underside of the slider tubes and pull the fork tubes out of the slider tubes. Remove the dust scrabbers [5]. MAINTENANCE WORK ON CHASSIS AND ENGINE » Cleaning the dust scrabbers of the telescopic fork The dust-protection bellows [1] are to remove dust and coarse dirt particles from the fork tube. However, after some time, dirt may also get in behind the dust-protection bellows. If this dirt is not removed, the oil sealing rings located behind it may start to leak. For this purpose, use a screwdriver to lift the dust scrabbers out of the slider tubes, clean them thoroughly with compressed air, spray the fork tubes and dust scrabbers with Universal oil spray (Motorex Joker 440) or engine oil. Then, push the dust-protection bellows into the outer tubes by hand. NO OIL MAY REACH THE FRONT TIRE OR THE BRAKE DISKS SINCE THIS WOULD CONSIDERABLY REDUCE THE TIRE'S ROAD GRIP AND THE BRAKING EFFECT OF THE FRONT BRAKE. 1 Changing spring preloading of the shock absorber 2 This is easily done. NOTE: Before changing the spring preload note down the basic setting, e. g. Change the spring preload with the adjusting ring [3] and re-tighten the locking ring [2].

USE AFTER PERIOD OF STORAGE ­ Fill up tank with fresh fuel. ­ Check motorcycle as before each start (see driving instructions). 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). [. . . ]
