Re
placing the air filter
element and cleaning the
check hose
The air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Have a Yamaha dealer replace
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.
