Yes, you can run a G1 Yamaha Golf cart without the oil injection system by mixing oil with the gasoline at a ratio of 40:1 or 50:1. However, it's essential to remove or disable the oil injection pump to prevent it from malfunctioning or leaking oil into the fuel system. Be sure to check the oil reservoir and lines to ensure they are clean and not obstructing the fuel flow. Regularly monitor the engine for proper lubrication and performance after making this change.
