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 226). If you do not have the skills or the tools, see your dealer.

Change the oil with the engine warm to assure complete and rapid draining.
