THROTTLE OPERATION
Check the throttle to swing for smooth
movement.
Measure the throttle to swing free play.
Free Play: 1_ 4mm
To adjust throttle free play:
1. Slide the rubber sleeves back to expose
the throttle cable adjuster.
2. Loosen the lock nut, then turn the
adjuster to obtain the correct free play.
(1~4 mm or 0.04~0.16 in)
3. Tighten the lock nut and reinstall the
sleeve.
OIL PUMP ADJUSTMENT
(Mongoose/KXR 50)
Open the throttle valve fully and check that
the index mark on the pump body aligns
with the aligning mark on the oil pump
control lever.
Reference tip alignment within 1mm of
index mark on open side is acceptable.
Start and idle the engine, then slowly open
the throttle to increase engine rpm and check
the operation of the oil pump control lever.
If adjustment is necessary, adjust the oil

2. Remove the air filter element, and
separate it from the box.
To clean the air filter element:
1. Wash the element gently but thoroughly
in solvent.
2. Squeeze the excess solvent out of the
filter and let it dry.
3. Inspect the element. If damaged, replace
it.
4. Apply quality foam air filter oil to the
element. If foam air filter oil is not
available, motor oil may be used.
5. Reinstall the element to the air filter case.
6. Reinstall the element assembly and parts
removed for access.
Apply the engine oil.
Squeeze out the excess oil.
CHANGE INTERVAL
More frequent replacement is required when
riding in unusually dusty or rainy areas.
Use parts cleaning solvent only. Never
use gasoline or low flash point solvents
which may lead to a fire or explosion.

If the compression is low, check for the
following:
- Leaky valves
- Valve clearance too small
- Leaking cylinder head gasket
- Worn piston rings
- Worn piston/cylinder
If the compression is high, it indicates that
carbon deposits have accumulated on the
combustion chamber and the piston head.

below.
Toe-in = B°– A
Toe-in: 0_ 15mm
If the toe-in is incorrect, adjust the toe-in
Adjust the toe-in step:
Mark both tie-rods ends.
This reference point will be needed during
adjustment.
Loosen the lock nuts (tie-rod end) of both
tie-rods
The same number of turns should be given
to both tie-rods right and left until the
specified toe-in is obtained, so that the
lengths of the rods will be kept the same.
Torque: 2.5_ 3.5kgf-m
• Be sure that both tie-rod are
turned the same amount. If not, the
machine will drift tight or left even
