REMOVING THE AIR FILTER
The next steps are equally as important as the oil
change. The next step is to clean the air filter and airbox;
we suggest putting on a pair of good latex shop gloves for
this. First, remove the air filter by using either a nut driver
or a flat-head screwdriver to loosen the air-filter clamp.
Once it’s loose, gently pull the air filter off of the airbox for
CLEANING THE AIR FILTER
This particular air filter is a dual-stage foam filter with
the top foam layer being removable. Remove the top layer
to clean both foam filters. We inspected the base filter, and
it was still visibly clean, so we will just clean the top layer.
Using a foam-filter cleaner, liberally spray the outside
and inside of the filter, then let the cleaning solution sit for
about 10 minutes or so to do its job.
CLEANING THE AIRBOX
During this time we suggest cleaning out the airbox with
a light degreaser fluid by spraying it liberally into the airbox. Be sure to keep any of the degreaser out of the intake
tube by stuffing a clean cloth down in the intake opening.
WASHING THE AIR FILTER
Once the airbox is clean, it’s time to wash out the air
filter with warm water. Squeeze it out, but don’t wring it or
twist it, and set it outside to dry. It could take a bit of time
depending on the weather for the filter to dry, but make
sure it dries completely.
APPLYING NEW AIR-FILTER OIL
After it’s dry, take either a spray-on foam-filter oil or a
bottle of foam-filter oil and apply it to the filter. With the
spray can, apply the oil on the outside of the filter in an
up-and-down pattern. When we use the foam-filter oil
bottle, we poke a small hole into the seal under the cap to
make life easy when applying it, because getting air filter
oil everywhere is not what you want to do! Once you have
the entire filter coated, work in the oil with your hands until
it’s completely covered. Let the air-filter oil-carrier solvent
evaporate, then pat the excess oil off with paper towels.
REINSTALLING THE AIR FILTER
Reinstall the outer foam filter to the base foam filter and
install the air-filter assembly back on the intake boot. Be
sure that the filter is installed correctly, then you can tighten the air-filter clamp to finish out the process.
