Carb interchange

Does anyone know if '81 1100 GK carbs can be used to replace E carbs. Yes I know some of the jets might be different but they both are BS34SS carbs and I will meed to rejet anyway.

The main air jets are different. They are the one jet you can't replace. It is at around five o-clock on the filter side of the carb.

Can the jet be redrilled to size? I've had to do this auto carbs before.

I've actually filled the jet with JB Weld and drilled it.
The 16 valve have a smaller jet.
Make sure you get all the epoxy shavings out.

Thanks for the idea. I have a chance to pick up a set of carbs for an 1100 GK fairly cheap and will have to rerack and rejet them anyway. I just wanted to know what the differences are.

For what it's worth, my 1100G has E carbs on it. E carbs have one of the idle bypass holes that is larger and the emulsion tubes, (neelde jets, not the needles), are smaller.

Bypass holes for a G are all .08mm and the emulsion tubes are X-3.

For an E, three of the bypass holes are .08mm and one is .09 and the emulsion tubes are X-1. Other than that, everything is the same, and you are correct, you will have to put the correct jetting for your bike.
