Question about Harley Davidson FXR Super Glide Motorcycles
Yes, there is!
It's called STRAIGHT PIPES!
Straight pipes never run right, except at wide open throttle on the track.
Beings you're running a (S&S) E carb, read item number 10, here:
It says, "NOTE: Drag or straight pipes can prevent you from obtaining optimum carburetor performance."
You didn't say if you were running the standard S&S air cleaner or not, but line 11 states" If the S&S teardrop air cleaner is being replaced with an aftermarket air cleaner be sure to remove the auxiliary bowl vent screw. Never use a velocity stack on a street driven motorcycle! Poor throttle response will be experienced."

You can download the service manual for nix from here. trying to picture what you are looking at, but if they are the only rubber hoses coming off the carby, then they are most probably the fuel lines. If they come off the very top of the carby, then they may be breathers. The bike has a vacuum operated petcock also, you will need to have it in prime position for the carbs to fill. Then once the engine runs, if the petcock os working correctly, then you should be able to get fuel in on position. Just cranking it over will not created enough vacuum for the carbies to fill.,hence the prime setting. Happy to answer any questions you may have about the bike, A FixYa rating is a great reward for my efforts to assist you. Cheers

SOURCE: 91 kx 250 stock carb setup.
Low speed screw 1.5 turns out from bottomed. Middle position for clip #3 position.
I never rely on the factory settings for the low speed screww, set it to factory and keep adjusting it 1/8 turn at a time until idle sounds best and quick throttle blips dont sound "stumbly" the later being the most important.
The needle position is for low altitude.

sounds like the main jets are partly pluged, you must remve all brass jets and seats including needle jet and its slide soak in carb cleaner and blow out with compressed air only.. hold up to bright light to verify if all are clean. jim
