Induction Silencer Maintenance and Cleaning
For the 501/01
– 03 – 05 models
fig. 3
The silencer serves to reduce the engine noise level and replaces the normal
air cleaner at the carburettor. For its correct operation, it must be maintained as
follows:
After about 3000
– 5000 km / 2000 – 3000 miles, rotate and remove the silencer top
#1, and then remove the silencer element #3. The element must be thoroughly
washed in clean petrol. Moisten the clean element with a mixture of oil and petrol to
the ratio of 1:1 and leave it to drip. After replacing the element, the silencer top is
secured against working free by rotating the top to engage the fitting clips to the
silencer body #22. Care should be taken to ensure that the rubber sleeve #4
connecting the induction silencer to the carburettor does not become distorted or
damage to prevent dirt entering the engine. The drain hole in the sleeve must always
face downwards.
A loose silencer top will manifest as a roaring noise when the engine is
running. In such a case, the element may fall out resulting in dirt entering the engine
as well as the mixture becoming lean and the engine loosing power at high r.p.m.
and overheating. On the other hand, with the element excessively dirty, the mixture
will become too rich resulting in increased fuel consumption and the engine running
lumpy / four-stroking.
The induction silencer is fitted to the bodywork with 2 bolts #26 which are
accessible after the removal of the silencer top and the element. The Induction
silencer is accessible after removal of the under seat luggage compartment and seat
/ this job will be described in a following chapter dealing with the bodywork/.
