Cleaning the air filter

The main air filter element and sub air filter ele-
ment should be cleaned every 20–40 hours of en-
gine operation. When servicing the air filter
elements, check the air filter case inlet for obstruc-
tions. Check the air filter case rubber joint to the
throttle body and the rubber joint manifold fittings
for an air-tight seal. Tighten all fittings securely to
avoid the possibility of unfiltered air entering the
engine.
TIP
 Replace the air filter elements if damaged.
 Service the air filter more frequently if you often
ride in wet or dusty areas.
 There is a check hose at the bottom of the air fil-
ter case. If dust or water collects in this hose,
empty the hose and clean the air filter case and
air filter elements.
