TOPIC: Drouin Supercharger

I am installing a later style Drouin Supercharger on my Norton and if I am not going to be using the built in throttle body or the injector. I am assuming that I should take out the slider and plug the injector and add a flat slide carburetor.

Yes pretty much a solid tube connecting the barb to the inlet to the blower.
This of course is the easy part...
You always get a screwin with a drouin
I had stockpiled early keihin/sportster throttle plate they are nicer smaller bore and fully tuneable including the accelerator pump.

okay awesome! do you still have the carbs?

Yes i have a few 2? If i can find them, I'll bring them for you to look and then you might try to source one or a few. "Having" is not an offer to sell....
