Default S&S Super G Jet Issue
I have an 85 Tour Glide with an 80" Evo. Put inch and 3/4 drag pipes on it just recently. It has a S&S Super G carb on it. What would be the recommended main and intermediate jet change size changes?

A G is entirely too big for an 80" motor.
I suggest you go back to an E.

What they said. Carb too big. And trash the drag pipes, IMHO.

yea, gotta agree here.

I've got a G on my 124, wouldnt even dream of running one that big on my 80"

carbs (venturis) work on velocity. you're slowing down the incoming air BIGTIME with a venturi that big.

That is a big carb for an 80" but it might work with a 28 inter. and 66 main. Here is jetting recommendation out of a S&S manual. You can go to S&S web site an get this information. A good way to check if you have the right inter. jet is too go by the air mixture screw. It should be at about 1 1/2 turns out. If the engine runs best with the mixture screw turned out less than one turn, the intermediate is too large. If it is greater than 1 3/4 turns, intermediate probable too small.

Well, the previous owner had the motor re-built and upped the compression to 10:1. So I think that's why the G was used.

No I haven't. I turned the wrong screw to turn down the idle. I turned the idle enrichment screw by mistake and I can't find that "sweet spot" to which it'll even run.
