Cleaning the air filter elements

The air filter elements should be cleaned at the in-
tervals specified in the periodic maintenance and
lubrication chart. Clean the air filter elements more
frequently if you are riding in unusually wet or dusty
areas.
TIP
There is a check hose at the bottom of each air filter
case. If dust or water collects in these hoses, empty
them and clean the air filter elements and air filter
cases.
