Replacing the air filter ele-
ment and cleaning the check
hose

placed at the intervals specified in the

the air filter element more frequently if
you are riding in unusually wet or dusty
areas. However, the air filter check
hose can be easily reached and should
be frequently checked and cleaned if
necessary.
To clean the air filter check hose
1. Remove the air filter check hose
under the air filter case.
2. Clean and then install the hose.
