Spark Plugs
When replacing spark plugs on the Kawasaki FD620D Liquid Cooled OHV Engine,
it is extremely important to pay strict attention to the specification number of the
engine being serviced. All Conquest vehicles manufactured prior to vehicle serial
number CB17857 require spark plug part number 92070-2072. Vehicles produced
from CB17857 with a specification number of HS12 or later require spark plug
number 92070-2112.
Kawasaki has made changes to the Cylinder Heads, Head composition, & spark plugs
of the FD620D. The newer spark plugs are longer and will cause damage if used in
an older spec. engine.
All ARGO engines are equipped with a foam precleaner and dry paper air filter element
housed in an air cleaner assembly attached to the carburetor.
Wash and oil the precleaner after every 25 hours of operation or more often under
extremely dusty or dirty conditions.
Check the paper air filter element every 100 hours of operation or more often under
extremely dusty or dirty conditions.
For instructions to remove, clean and replace the air filter components, refer to the air
cleaner section of the engine owner’s manual.
Remove and inspect the spark plugs after every 100 hours of operation. Clean the plugs
and reset the gap as detailed in the engine owner’s manual.
Replace the spark plugs if the electrodes are corroded or damaged or if the insulator is
cracked. Use the correct plug for the engine as detailed in the engine owner’s manual.
Re-install the spark plugs carefully, taking care to start the threads properly. Torque the
plugs to 10 - 15 ft. lbs (14 to 20 N·m). Do not over tighten.
