supply lines and the existing pulse line) with nylon
clamp provided. (Ref. Fig. 9 on Page H-8)

tate the placement of required decal.

Reconnect the negative ground to the battery.
FUEL AND STORAGE
Fuel should be fresh, clean unleaded 87 (minimum)
octane.
Methanol and other alcohol based fuels are hygroscopic
fuels which attract and retain moisture. These types of
fuels can attack the aluminum fuel pump and carburetor,
and should be avoided.
Prolonged Storage
The recommended storage method is to operate the
vehicle for the later part of the operational season with
fuel stabilizer added to the bulk storage tank according
to the manufacturers directions. Maintain as little fuel as
possible in the individual vehicle fuel tank. It is desirable
to use
fresh
fuel with the correct octane rating. Attempt
to minimize bulk storage of fuel over the winter months.
For winter or prolonged storage, raise the rear of the
vehicle (see lifting instructions in Section B) and support
on jack stands. Add fuel stabilizer to the tank in accor-
dance with the manufacturer’s recommendations. Dis-
connect the fuel line from the engine at the fuel tank.
With proper ventilation, start the engine and allow to run
until the engine stops due to lack of fuel. Drain carbure-
tor bowl using drain screw and re-tighten the drain
screw. Remove the air filter and spray a commercial fog-
ging or cylinder oil into the carburetor while operating
the starter for 2 - 3 seconds. Reinstall the air filter and
reattach the fuel line to the tank.
When vehicle is to be used again, the carburetor bowl
float drain valve must be closed and fuel tank filled with
fresh 87 (minimum) octane fuel. The addition of fresh
fuel mixed with the small quantity of stabilized fuel left in
fuel tank will provide satisfactory fuel to operate vehicle.
The fuel tank can be removed only by removing the rear
body, seat support panel and seat frame and unbolting
the tank (see BODY section).
