AIR FILTER
The air filter is the respiratory system of your
motorcycle. Its role is to filter our small particles and
impurities in the air that is drawn into the engine prior
to combustion with the fuel. Clean air will extend the
engine life.
If the air filter is clogged with dirt and oil, the air intake
resistance will be higher and this will lead to a lack of
power, increased fuel consumption, poor starting and
increased exhaust emissions.
Once blocked, dirt will pass through the filter and into
the upper cylinder area, causing accelerated engine
wear. Clean and replace the air filter according to the
service schedule and driving conditions.
TO CHANGE/CLEAN THE FILTER
1) Remove the left frame cover to reveal the air filter
case.
2) Remove the case cover screws. Remove the air
filter element.
3) Tap the filter on a flat surface to remove large
pieces of debris. Then wash the foam filter and allow to
dry. Apply foam filter oil, and wring out.
4) If the filter is torn or damaged, replace it with a new
genuine spare part. Spare parts can be
purchased from your AJS Dealer or directly on line at
www.ajs-shop.co.uk
5) Wipe the inside of the air filter case clean.
6) Clean out the air filter case oil trap.
7) Reinstall the air filter element and case covers in
reverse order. Be sure to seal the air filter correctly.
Failure to replace a dirty or damaged air filter
will shorten the life of your engine.
