Mikuni carb

[geezer101]

This is the tricky part with installing an electric fuel pump on a Mikuni carb. You need to be able to split fuel delivery between the primary fuel inlet and the accelerator enrichment pump on the side of the carb. In this regard you can't delete the fuel return line. It is the only outlet for excess fuel to bypass the accelerator pump. Take a look at this post - especially the first image as it has the fuel recirculation cannister you will need to make your mechanical fuel pump delete operate properly (the can with the hoses and coloured tape on it).

If you try to run a single fuel delivery to the carb, you'll lose the accelerator pump and it will end with a bad flat spot from closed throttle.
