This '77 Ironhead that I picked up a while ago has a Super E carburetor. The motor is stock and runs well but it seems to be running a bit rich. This is the first bike I've had that runs an S&S of any model and I don't know a whole lot about them. I'm wondering if it's over carbed for the motor or if there are specific jets that I could get that would be a better match for this set up? I haven't yet tore into the carb to see what jets are in there but am going to tomorrow.
