Fuel filter
The fuel filter is incorporated in the fuel valve which is
mounted on the bottom left side of the fuel tank.
Accumulation of dirt in the filter will restrict the flow of
the fuel to the carburetor. Therefore, the fuel filter
should be serviced frequently.
To service
1. Drain the fuel from the fuel tank into an approved
gasoline container. Disconnect the fuel line.
2. Remove the fuel valve by removing the bolts. Wash
the fuel filter in high flash-point cleaning solvent.

3. Reassemble the fuel valve in the reverse order of
removal. Make sure the O-ring is in place.
Install the fuel valve in the fuel tank.
Refill the fuel tank.
Attach the fuel line and turn the fuel valve to ON;
check for leaks.
•
Gasoline is extremely flammable and is explosive
under certain conditions. Perform this operation in
a well-ventilated area with the engine stopped. Do
not smoke or allow flames or sparks in the area
where gasoline is drained or stored and where the
fuel tank is refueled.
CARBURETOR
NOTE:
•
The standard carburetor settings are ideal for the
following conditions: 32-to-1 premix ratio using
Pro Honda HP2 2-stroke oil or its equivalent, sea
level altitude, and 20
°
C (68
°
F) air temperature. If
your conditions are different, you may need to
adjust the carburetor settings, using the tuning
information on page 50. Confirm your settings are
correct before proceeding.
Minor adjustments
1. Adjust the carburetor settings using the tuning
information on page 50.
2. When the engine is warm enough to run without the
choke, push the choke knob down to its off position.
3. Loosen the lock nut and turn the throttle stop screw
to obtain the smoothest idle:
•
To increase idle speed, turn the screw clock-
wise.
•
To decrease idle speed, turn the screw counter-
clockwise.
4. Tighten the lock nut while holding the throttle stop
screw.
5. Adjust the air screw to obtain the best off-idle
performance.
•
If the engine blubbers (rich) exiting a corner,
turn the air screw counter-clockwise to lean the
mixture.
•
If the engine surges (lean) exiting a corner, turn
the air screw clockwise to richen the mixture.

NOTE:
•
The minimum to maximum range of air screw
adjustment is 1 to 3 turns out from the lightly seated
position. If you exceed 3 turns out, the next smallest
slow jet is needed. If you are under 1 turn out, the
next larger slow jet is needed.
FRONT AND REAR WHEELS AND TIRES
Tires
Proper air pressure will provide maximum stability,
riding comfort and tire life.
Check tire pressure frequently and adjust if necessary.
