FUEL SYSTEM
Read all of Section Band this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings
Turn the carburetor upside down. Remove the bowl. With
the carburetor inverted, the 'B' side top edge of a prop­
erly adjusted float will be slightly above parallel to the
bowl gasket surface and both sides of the float will be
level with each other (Ref Fig. 5 on page H-5). If the
sides of the float are not parallel or if the 'B' side of the
float is not slightly above parallel with the bowl gasket
surface (.030" - .060") (.8 - 1.5 mm), an adjustment is
required. Adjust by inserting needle nose pliers into the
slot on the top of tang #1 and hold firmly while adjusting
the floats by gently lifting or pushing with the other hand.
Reinstall the bowl, copper gasket and the screw. Check
for fuel leaks.
After adjusting the float level, reassemble the carburetor
in the reverse order of assembly. The pilot screw is fac­
tory set.
Check for free movement of the choke shaft before
installing the carburetor. Lubricate the bushings with WD-
40
®
oil or equivalent.

Throttle Shaft Adjustment
To adjust the throttle shaft (9) and throttle valve (10), turn
the throttle stop screw (11) counterclockwise until it no
longer contacts the tab on the throttle shaft (Ref Fig. 4 on
page H-4). Hold the throttle shaft in the closed position,
then turn the throttle stop screw clockwise until it con-
tacts the tab on the throttle shaft; turn the screw clock­
wise 1/4 turn.
Carburetor Installation
Replace carburetor and air box in reverse order of disas­
sembly. Use a new gasket to ensure sealing of carbure­
tor. Tighten hardware to 50 - 70 in. lbs. (6 - 8 Nm) torque
(Ref Fig. 3 on page H-3).
.A_ WARNING.A_
Clogged or kinked carbu­
retor hoses are not only
detrimental to the proper
operation and performance of the vehicle, but can
also be a safety hazard in the case of fuel leaking on a
hot engine.
CAUTION
Do not let the carburetor vent hoses
become clogged or kinked. Engine heat
will cause the fuel in the carburetor bowl to expand and may
result in fuel being expelled from the carburetor if unable to vent
through the vent tubes.

FUEL PUMP
The fuel pump is mounted on the vertical seat support on
the passenger side and is operated by crankcase pres­
sure impulses from the engine. As the pistons move up in
the cylinders, a negative pressure moves the diaphragm
(1) within the fuel pump (Ref Fig. 6 on page H-5). This
movement draws fuel from the fuel tank into the fuel
pump chamber (2) through the inlet valve (3). This action
also closes the outlet valve (4) which prevents fuel back­
flowing from the carburetor.
