I just wanted to start a thread regarding peoples experiences with the S&S super E carbs..

I have been thinking of buying one for my FXDX and wanted feedback on the S&S carbs only. Jetting specs, fuel mileage, flat spots, coughs, rideabilty,etc etc....

Just anything you have experienced with the Super E carbs, good or bad.

 

Well, I my 02 has one. I need to mess with to get it running great. It doesn't like to start up without the choke up or I have to hit the throttle a few times to keep it running. If I don't it will fire up and then sputter out and die. However, when it does that it shoots a cool little flame out of the exhaust pipe. After it is running it is a little rough off idle from a stop. But nothing bad, you get used to it. Throughout the rpm range it seems to run fine, maybe a little rich. The other night I think I saw a flame shoot out the exhaust when I went from just cruising to WOT. Then on the deceleration I am getting a lean pop. I just bought the bike a month ago, so I am reading up on jetting it and tuning to get it running better.

But honestly I have kinda gotten used to it the way it is.

 

I have ran s&s on everything from ironheads to shovels and evos . I love them , easy to work on and set . there are better proformance carbs out but I do love super e carbs , super b not so much .

 

3 throttle pulls and choke is normal s&s start up , but the rest is not right on your carb , you need to adjust airfuel or change jets

 

Mine does just fine other than throttle response straight off idle if I just twist it wide open, anything at all above idle and it's right there. No other problems and fuel mileage ranges around 45-50MPG if I just cruise. Dead cold, enrichener without a throttle twist and just hit the starter after it's warm. Stock other than open drag pipes and EV-27 cam.
I see the S&S like a Holley and the CV like a Quadrajet, both tuneable in their own ways.

 

This is exactly the kind of feedback I was looking for.

I like to ride aggressively since I came from a Sport Bike background. I just want to be sure that the Super E can be jetted to roll on smoothly, and not cough or flat spot exiting corners.

 

I set my idle at 1100rpms so I don't have lag off idle

 

Yep, I prefer a good idle speed also. We have alot of 50 MPH 4 lanes here with stop lights. Bogging or stalling off the line is dangerous here.

 

The S&S E has an adjustable accelerator pump. That carb can be tuned spot on with a little work on your part! I've owned 2 of them and loved them both. There's something about the classic look of the AC cover that gets my blood up! As you no doubt know, the kit comes complete with all the parts from the heads to the air cleaner. Changing main jet is simple...just drain the carb bowl and pull the plug. S&S sells a main jet wrench...it is worth every dime. If I had a carbed Harley, it would be an S&S E...NOTHING else!

 

I have been all over the adjustment on the accelerator pump with minimal results, probably just needs the diaphragm. I'm not one to sit at a stoplight and whack the throttle so it works just fine for me. Never had a problem leaving from a dead stop, full throttle on takeoff isn't that important to me.
