Air Filter 

Air Filter Maintenance 

To maintain the highest performance from your 
engine and to reduce excessive wear that could 
cause engine failure the engine requires a 
continuous flow of clean air. Air is taken into the 
engine through an air filter to clean the air prior to 
mixing it with fuel and oil in the carburetor. 
 
During normal operation the filter accumulates 
dirt from the air and will need to be cleaned to 
maintain the proper air flow. The filter should be 
cleaned every 3000 miles, more often if you ride 
in a dusty or dirty environment and the element 
should be replaced every year. 
 

The air filter box is located on the left side of 
the engine under the body cover. It is a black 
box about 6” square and is attached to the 
crankcase with two bolts and the carburetor by 
a tube. 
 

To clean the filter 

Remove the air filter box cover. 
Remove the filter element from the air box. 
Wash the element in a non-flammable solvent 
such as Air-Filter cleaner from your local auto 
parts dealer. 

1.  Dry the element completely before 

continuing. 

2.  Soak the element in clean engine oil 

until completely saturated. 

3.  Squeeze out the excess oil until the 

element does not drip any oil. 

4.  Allow the element to dry then reinstall 

the element and cover.
