Changing Engine Oil & Filter
Refer to Safety Precautions on page 119.
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 214). 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 seat (page 130) and
the tank cover assembly (page 132), and then remove the engine
oil fill cap from the front right crankcase cover.
