To adjust the oil injector on your 1979 Yamaha GT 80, first locate the oil pump, typically found near the engine. Then, loosen the adjusting screw or nut to change the oil flow rate; turning it clockwise usually decreases the flow, while counterclockwise increases it. Make sure to check the oil level in the reservoir and run the engine briefly to ensure proper oil delivery. Always refer to the service manual for specific adjustments and procedures related to your model.
Yamaha engines are oil injected, if it is a fresh engine, or injector not working use a 50 to 1 mix.

To bypass the auto-injector system on a Yamaha PW 80, you can disconnect the oil line from the injector and plug it. Then, mix oil with fuel manually at the recommended ratio (typically 50:1) and ensure the fuel tank is filled with this mixture. It's important to monitor the oil and fuel levels closely to avoid engine damage. Always consult the owner's manual for specific instructions and safety precautions.
