CLEANING
Clean bike at regular intervals so as to keep plastic parts surface in good conditions.
We recommend using hot water with a detergent usually available on the market and a sponge. Strong dirt can be removed with a
light water jet.
Never clean the bike with a high-pressure cleaner or a strong water jet! Water high pressure could reach electric components,
connectors, Bowden cable commands, bearing, carburettor, etc... and cause damage or lead to the early breakage of these
parts.
- For engine washing, use cleaners available on the market. Very dirty points will have to be cleaned with a special brush.
STORAGE
Should you plan not to ride the bike for a long time, take the following actions:
- Change engine oil, oil filter and fine mesh filter (an old oil contains harmful impurities).
- Check anti-freeze and coolant levels.
- Heat the engine up again, close fuel cock, and allow engine to turn off by itself.
Then open the drain screw positioned onto carburettor tank to drain off also the remaining fuel.
- Remove spark plug and pour approx. 5 cc of engine oil inside cylinder through spark plug hole. Operate kick start pedal 10 times
in order to let engine oil be distributed on cylinder wall, then refit spark plug.
- Drain fuel from tank, and collect it inside a special container.
It is not recommended to start the engine, just for a short time, of a bike during a long inactivity period. Engine would not heat
enough up and, consequently, the water vapour created during combustion would condensate and lead to rusting of easily-
oxidizable parts.
RESTART AFTER INACTIVITY
- Fill tank with new fuel
Before bike seasonal inactivity, check all parts for wear and operation. Should some maintenance, repair or change works be
necessary, have them carried out during inactivity as workshops will be less busy during this period. Long waiting times at the
workshops at the beginning of the season can be thus avoided.
