How to modify the motorcycle EFI system?

First, the carburetor of the original car needs to be removed and replaced with the throttle body, and the intake manifold can be used on the original car.

Secondly, install the fuel pump assembly and oxygen sensor.

Third, finally connect the wiring harness and you're done.

4. Note: When installing the oxygen sensor, the base should be welded on the exhaust pipe close to the engine, and the position should not be too close to the exhaust port. The included angle between the axis of the assembly hole and the horizontal plane should not be less than 10-15 degrees, which can reduce the possibility of condensation water accumulation near the sensor head or itself and minimize the possibility of damage.
