3-20 Air Cleaner
This model is equipped with a reuseable, oil impregnated, foam air filter. It must be removed and cleaned at least once
a month, and more often if the motorcycle is ridden mainly in the dirt-preferably each time after you spend the entire
day in the dirt 10- 10 hours operation).
1) Remove the air cleaner mounting bolt and loosen
the air cleaner. (JT2•JT2M)
2) Remove the air cleaner case cap. {JT2~JT2M)
