Safety Precautions: Refer to page 111.

Proper air cleaner maintenance is very important for off-road vehicles.

NOTICE: Using the wrong air cleaner may result in premature engine wear.

NOTICE: Improper or lack of proper air cleaner maintenance can cause poor performance and premature engine wear.

Unlatch the spring hooks (1) and retainer clips (2).

Remove the air cleaner housing cover (3).

Loosen the screw (4) and remove the air cleaner assembly (5) from the air cleaner housing.

Warning: This maintenance check requires trained personnel with PPE!

Service the air cleaner housing drain tube according to the Maintenance Schedule. Service more frequently after riding in very wet or muddy conditions.

Are there deposits in the drain tube?

If deposits are present, clean the tube before starting the vehicle.

Remove the drain tube by removing the clip under the air cleaner housing.

Reinstall the drain tube, securing it with the clip.

Sign off on the air cleaner housing drain tube maintenance.

Engine oil quality is a major factor that affects both the performance and the service life of the engine.

Using the proper oil (page 131) and filter, and regularly checking, adding, and changing oil will help extend your engine’s life. Even the best oil wears out. Changing oil helps get rid of dirt and deposits in the engine. Operating the engine with old or dirty oil can damage your engine. Running the engine with insufficient oil can cause serious damage to the engine and transmission.

Change the engine oil as specified in the maintenance schedule on page 114. When running in very dusty conditions, oil changes should be performed more frequently than specified in the maintenance schedule.

Refer to Safety Precautions on page 111.

Your ATV’s oil filter has very specific performance requirements. Use a new Honda Genuine oil filter specified for your model or a filter of equal quality.

NOTICE: Using the wrong oil filter may result in leaks or engine damage.

This procedure requires mechanical skill and professional tools such as a torque wrench as well as a means for disposing of the drained fluid (page 206). If you do not have the skills or the tools, see your dealer.

Refer to Safety Precautions on page 111.

The spark arrester must be serviced every 100 operating hours to maintain its efficiency.

Regular servicing prevents carbon build up (which can diminish engine performance) and also complies with USDA regulations for regular maintenance to assure proper function. The spark arrester prevents random sparks from the combustion process in your engine from reaching the environment.

The use of safety glasses is recommended for this procedure.

Because of the possible fire hazard, check that there are no combustible materials in the area before purging the spark arrester.

1. Select a well-ventilated area free of combustible materials and make sure the exhaust pipe is cool.

3. Start the engine and rev it up approximately twenty times while momentarily creating exhaust system back pressure by blocking the end of the muffler with a shop towel.

Use only the recommended type of spark plug in the recommended heat range. Using spark plugs with an improper heat range can cause engine damage.

Refer to Safety Precautions on page 111.
