Cleaning the dust sleeves of the telescopic fork
The dust-protection bellows [3] 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.
Use a screwdriver to lever the dust-protection bellows out of the outer tubes and slide them
downward.
Clean dust-protection bellows, outer tubes, and fork tubes thoroughly, and oil them thor-
oughly with Universal oil spray (Motorex Joker 440) or engine oil. Then, push dust-protec-
tion 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.
Checking the chain tension
Place the motorcycle on the side stand and switch the transmission to idle. Press the chain
upwards under the lower chainguard screw [4]. The difference to the sagging chain should
be 35 - 40 mm (1.37 … 1.57 in).
– 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.
