4. Cable & hose routing

Route cables, hoses and wires as per photos II.9 and II.10. Be sure seal cable ends with

tape and leave some slack in throttle cable near carburetor. Use a small zip-tie to secure cable
boots and seal out dirt and water. Make sure to always replace vent hose onto vent fitting to
prevent contamination of transmission. Check and clean carburetor vent hoses as needed to
keep carburetor working properly. Clogged vent hoses can cause the carburetor to malfunc-
tion and can result in engine damage.

5. Fuel & oil requirements

Fuel requirements

- Hi-test pump gasoline is recommended for your motorcycle with a min-

imum octane of 92-94. This octane rating is necessary to prevent possible detonation (ping-
ing) and damage to piston from low octane fuel. If “pinging” or “knocking” occurs, check ignition timing, jetting, plug color, and
piston dome for carbon deposits. An air leak can also cause these symptoms. 

The fuel must be mixed with the proper type and

amount of oil or severe engine damage will result. 

Note:

Race fuel is not required unless the compression of the motor has been increased. Race fuel burns slower and will decrease the

acceleration of the motorcycle. Even with increased compression, a 50/50 mixture of race gas and pump gas should be sufficient to
prevent detonation.

Oil requirements - 

The fuel must be mixed with the proper type and amount of oil prior to fueling the motorcycle. The oil is

required to lubricate the crankshaft bearings, rod bearings, piston, rings and cylinder walls. The transmission oil only lubricates the
clutch and transmission, it does not lubricate the engine components in a 2 cycle engine. The oil must be specifically recommended
for premix use in motorcycles or the oil may not provide enough lubrication, cause piston rings to stick, cause heavy deposits in
engine and foul spark plugs, or separate from the gasoline. The use of Maxima brand K2 premix oil is strongly recommended. If this
product can not be obtained, use a synthetic or semi-synthetic 2-stroke premix oil specifically for motorcycle use. 

The oil must be mixed with the fuel at a ratio of 40:1 (40 parts fuel to 1 part oil) Graduated containers can be purchased which

show the proper amount of oil for various quantities of fuel for any common ratio. One common type is called the “Ratio Rite

,”

which can be purchased at most motorcycle stores. Otherwise, to obtain a 40:1 ratio, use 3.2 fluid ounces of oil per 1 gallon of fuel.
(6.4 ounces for 2 gallons, 8 ounces for 2

1

2

gallons, 16 ounces for 5 gallons, etc.) If measuring in liters, use 25cc oil per litre of fuel.

To mix oil with fuel, fill mixing container with

2

the desired amount of fuel. Add the proper amount of oil (for the total amount of

fuel) to the fuel in the container. Tightly cap and secure vent on container, then vigorously swirl and slosh fuel to mix oil. Add other
half of fuel and continue to mix thoroughly. Mix at least 1-2 minutes. Release fuel pressure using vent before opening container, be
cautious of flammable fumes. 

Never add oil to gas tank of motorcycle!

Always mix fuel and oil thoroughly in a separate container

before fueling motorcycle, otherwise the oil will clog the fuel filter and jets in the carburetor and cause severe starting and running
problems. Do not store gasoline any longer than necessary, as it loses its potency over time. An approved metal container is best for
storage. Do not store fuel mixed with oil. Mix only enough fuel and oil to be used in a short time. Take great care that water or dirt
does not contaminate fuel or gas tank.
