1. Release and flip the toggle clamps
back.
2. Back the auxiliary tube away from
the housing (or pull it off, if
necessary), remove the top of the
air filter housing, then push the top
half of the filter toward the engine;
this will pop the bottom half free of
the ridge at the bottom of the air
filter box.
3. Pull up on the filter element to remove it.
4. When installing the new filter, make sure the bottom half engages the
ridge at the bottom of the air filter box first, then push the top half
down and back. If not installed properly, the top of the air filter assembly
will not close. Push the auxiliary tube back on (or re-install it, if
removed).
When servicing the air filter, always be sure that the auxiliary
hose is not kinked or obstructed and that it is placed back into
the hole in the front cowl near the back of the headlamp. Check
all hose and wiring positions. Failure to do so may result in
severe engine damage when driving through deep water and/or
encountering unusually heavy precipitation conditions.
