6. ADJUSTMENTS:
A. Tire pressure 24 to 26 lbs. front; 26 to 30 lbs. rear.
B. Brakes: Check and adjust as described in Owners' Manual.
C. Horn: Check for proper operation.
D. Lights: Check all lights for proper operation.
E. Axle Nuts: Be certain that both the front and rear axles are properly secured.
F. Check the chain and adjust as required.
7. The engine should now be started and the carburetor adjusted for proper idle speed. It should be noted
that oil injector pump can be checked by visibly watching the oil flow through the plastic oil line.
• Note: When the throttle is closed, and the engine is not operating, the oil pump control arm may not
return to the stop pin when the throttle is operated. The oil pressure in the pump sometimes holds the
arm in an open position, but operating the kick starter or engine will allow it to return to its closed
position.

1. OIL INJECTION: The oil injection system is factory adjusted for proper operation. Fill the oil supply
tank with 2-cycle oil. Be certain to instruct the purchaser to regularly check the oil supply through the
glass inspection port. Caution: It must never be allowed to run dry.
2. FUEL: Fill the fuel tank with a 20-1 mixture of regular gas and 2-cycle oil (1 quart of oil in 5 gallons of
gasoline). This mixture is to be used during the first 250 miles of operation only. Thereafter, instruct the
customer to fill the tank with "regular" gasoline only.
3. BATTERY: Fill and charge the battery.
4. TRANSMISSION: Fill the transmission case with 25 ounces of SAE 10W30 motor oil. Transmission oil
level is checked by removing the oil level plug located just in front of the kick starter shaft. Do not
overfill the transmission case.
5. OIL PUMP GEAR BOX: The Oil Injection pump is gear driven by the crankshaft, and gear cavity oil
level must be checked before operation.
• The gear cavity is located behind the oil pump and left carburetor. This cavity must be kept filled with a
good grade of 30 weight motor oil. To fill, proceed as follows:
A. Remove left carburetor cover.
B. Remove oil level screw. This oil level screw is easily identified because it has a red fiber gasket under it.
C. Remove the screw just to the right of the oil pump body. Using a pressure-type oil can, fill the gear cavity
through this screw hole. Fill until oil appears running out of the oil level screw hole. (Oil level should
reach lower edge of this oil level plug screw hole).
D. Replace both screws. Oil level should be checked during the first 500 miles and intermittently thereafter.
6. ADJUSTMENTS:
A. Tire Pressure – 24 to 26 lbs. Front
26 to 30 lbs. Rear
