Special Care According to Track
Conditions
In dry, dusty conditions (such a volcanic ash or
fine powdery dust), special care must be given to
keeping the air cleaner element clean.
When riding on wet, heavy clay, mud adheres to
the tires and other parts of the vehicle. The mud
can add significantly to the weight of the vehicle
and therefore reduce performance. Take care to
remove built-up mud from the tires and chassis
after each ride, before drying occurs.
The engine works hardest in muddy conditions
and the radiator can become clogged with mud.
Take care not to overheat the engine in these con-
ditions.
The engine also works very hard when
riding in deep sand.
In muddy or sandy conditions, increase chain
slack as the chain and sprockets will be packed
with mud or sand, which reduces chain slack.
Check chain and sprocket wear frequently when
riding in mud or sand, since wear is increased in
these conditions.
In very dusty conditions, as the air cleaner collects
dust, the mixture becomes richer and it may be
advisable to apply slightly leaner jetting (main jet).
