Engine Oil & Filter
Changing Engine Oil & Filter
Refer to Safety Precautions on page 103.
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 202). 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.
Drain the Engine Oil:
1. With the ATV on level ground, remove the oil check lid (page
125) and the oil fill cap/dipstick from the front crankcase.
