3- Always lubricate the chain after washing the motorcycle. Dirty chains
can be cleaned with diesel fuel. A good quality chain lube spray
reduces chain wear and improves the efficiency of the transmission.
4- If you need to remove or change the chain, remember to replace
the clip on the split link with the closed end facing in the direction
of travel (photo 33).
DANGER. Never fit a new chain to worn sprockets or vice-versa.
Incorrect wheel alignment not only causes rapid chain and sprocket
wear but also affects the handling and control of the motorcycle.
DANGER. Loose, worn or badly aligned chains can break or come off
the sprockets. If this occurs the chain can jam the rear wheel and cause
accidents with serious personal injury and damage to the motorcycle.
7.12 ADJUSTING THE REAR SHOCK
The shock is set up in the factory with standard adjust.
SERVICING:
1- Check the spring for damage or wear.
2- Bounce the rear of the motorcycle up and down and check that the
rear suspension functions smoothly.
3- Check that the shock rod is perfectly straight and that there are no
oil leaks around it.
4- Push the rear wheel sideways to check for play in the swinging arm
bushings. Replace the bushings immediately any play is detected.
7.13 ADJUSTING THE FRONT FORK
The front fork is set up in the factory with standard adjust.
SERVICING:
1- Check that the fork seals are clean and free from oil, dust and dirt.
2- Check the legs for oil leaks. Replace damaged fork seals before
using the motorcycle.
3- Before riding the vehicle, apply the front brake and bounce the
front of the motorcycle up and down to check that the front fork is
functioning smoothly.
ENGLISH
7.14 FUEL
32
Only use car petrol with an octane rating of 96 to 100 or more. In
case of pre-ignition (knocking) try a different brand of fuel or a
higher octane rating. Fuel tank capacity is 3 litres.
7.15 FUEL FILTER
The fuel filter is incorporated in the fuel tap under the tank. As dirt
builds up in the filter it gradually impedes the flow of fuel to the
carburettor. For this reason the filter must be cleaned regularly.
SERVICING
1- Drain the fuel out of the tank into a clean petrol can.
2- Unscrew the two fixing screws and remove the fuel tap from the
tank.
3- Wash the filter in water with neutral soap. Leave the filter dry, in
the sun if possible.
4- Replace the fuel tap on the tank, making sure that the seal is
correctly seated.

DANGER. Petrol is extremely inflammable and petrol vapour can
explode easily. Only drain the tank in a well ventilated area and with
the engine switched off. Refrain from smoking and avoid all naked
flames or sparks while draining fuel or refuelling.
7.16 WASHING THE MOTORCYCLE
Cover the following parts to prevent water from entering before
washing your motorcycle:
- the throttle control
- the brakes control
- the air intake and filter
- the exhaust hole.
Avoid directing jets of water directly on to the following parts:
- the wheel hubs
- the swinging arm pivot
- the steering head
- the brake callipers
- the spark plug hood.
On completion of washing, lubricate the above parts as necessary then
start the engine and leave it run for a few minutes.
WARNING. Clean the vehicle when engine is cold.
WARNING. Never use solvents or alcohol to clean the plastic parts.
Use only water and soap or the appropriate detergent.
WARNING. Make sure that the brakes are fully efficient before you
start riding the motorcycle.
