Special Care According to Track
Conditions
•
In dry, dusty condit
ions (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 m ud
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.
•
Theenginework
s hardest in muddy conditions
and the radiator can become clogged with mud.
Take ca re n ot t o o verheat the eng ine in these con-
ditions. The e
ngine also works very hard when
riding in deep sand.
•
In muddy or sandy cond
itions, increase chain
slack as the chain and sprockets will be packed
with mud or sand, which reduces chain slack.
•
Check chain and spro
cket wear frequently when
riding in mud or sand, since wear is increased in
these conditions.
•
Sticking muds or du
sts on the front fork inner tube
and rear shock absorber rod could damage to the
oil seal, leading to an oil le ak. Clean the s ticking
muds or dusts from
the front fork inner tube and
rear shock absorber rod after each ride.
•
In very dusty conditions, as the air cleaner collects
dust, the mixtur
e becomes richer and it may be
advisable to apply slightly leaner jetting (main jet).
