The fuel filter is located in the fuel line about 12"  from the 
carburetor on the side of the engine. Replace the filter 
yearly. Prior to the removal of the old filter, note the direction 
of fuel flow as indicated on the filter. Have towels readily 
available in order to quickly remove any fuel leakage. 
Always use new hose clamps and ensure the security of the 
new filter by lightly pulling on each hose. Always perform 
maintenance outdoors or in a well

 

ventilated area. Do not 

smoke or allow any open flames in the vicinity of any 
maintenance activities. 

3.2 Changing your fuel filter :

1) Locate your fuel filter and mark the direction it 

is facing.

2) Clamp each side of the fuel filter to minimize 

any gas spills.

3) Remove the clips from each side of the fuel 

filter and remove the fuel filter.

4) Place the new fuel filter in the same direction 

as the old and place clips back into place and 
remove clamps.

The air cleaner is the engine’s only defense against 
damaging foreign particles. It is very important that the 
air cleaner element is inspected prior to each use. 
Remove the element and tap its sides in order to remove 
debris. Do not blow the filter out using compressed air. 
Doing so will greatly reduce the air cleaners 
effectiveness. Replace yearly; more often in dusty 
environments. Adhering to these practices will help 
prevent loss of power and premature engine failure. 

3.3 Changing the air cleaner: 

1) Unlock the air cleaner cover and remove to

access the air cleaner.

2) Remove the paper element and precleaner.

3) Replace or wash precleaner in warm water

with detergent. Rinse and allow to air dry.

4) Lightly oil precleaner with new engine oil;

squeeze out excess oil.

5) Replace paper element and place precleaner

onto new paper element.

6) Install onto base and place cover back on and

lock into place.

3.4 Changing the spark plugs and checking the spark plug gap: 

1) Remove the wire on the spark plug and use a 5/8”

socket to remove the spark plug.

2) Check the gap on the spark plug to verify that it is

0.03 in using a feeler gauge.

3) If the spark plug is worn, overheated, wet or

carbon fouled replace the spark plug.

4) Install the plug into cylinder head and torque to 20

ft.-lbs. Be careful not to overtighten the spark plug.

Kawasaki FR730V 

This machine has an oil drain hose installed on the 
engine to allow for easier oil changes. Bad Boy  
recommends that the oil and filter be changed after 
the initial 8 hrs of use, and at intervals of 50 usage 
hours or yearly, whichever occurs first after that. The 
oil capacity is 2 quarts. Bad Boy 10W-30 synthetic 
blend engine oil is recommended for maximum 
protection. 

3.1 Changing your engine oil and oil filter: 

1) Remove oil dipstick and open oil

drain using a 10 mm socket or a
flat head screwdriver until oil
begins flowing. Allow oil to
completely drain. (Make sure to
have an oil pan ready to capture
old oil and properly dispose old
oil.)

2) The oil filter is located on the right

side of the engine. Clean area
around oil filter. Place a container under the oil
filter to capture any
oil and remove filter. Wipe off mounting surface
and reinstall
drain plug. Torque to 10 ft.-lb.

3) Place new filter in shallow pan with open end

up. Fill with new oil until
oil reaches the bottom of the threads. Allow 2
minutes for oil to be absorbed by filter material.
