All the parts needed for the standard dual
stage air foam filter.
Take the air filter connector and fit the
short side to the air filter holder.
Use a zip ty to secure them.
Cut off the extended part of the zip ty using a sharp hobby knife.
Take the inner air filter foam and put it in
a plastic bag.
The kit does not comes with air filter oil.
We used R&B transparent RICINUS/METHANOL based air filter oil.
You can use standard BLUE colored MotoCross based air filter oil too.
Apply oil to the foam.
Massage the oil thoroughly through the foam
so it is evenly spread.
Take a paper towel or an old T-shirt and
massage all excessive oil from the foam filter.
Slide the second stage foam air filter on the
air filter holder and fit the end cap.
Secure the end cap with 3 x 8 mm round head hexagon screw using a 2 mm
hexagon tool.
Now place the first stage air filter foam.
In case of very dusty track conditions you can prepare this first stage
air filter foam too with air filter oil.
Fit the air filter connector to the neck of
the carburator and use a zip ty at the red marked spot to secure it.
Cut off the extended part of the zip ty using a sharp hobby knife.
Nice the car comes with a
dual stage foam air filter.
Shame there is no air filter oil supplied.
