There's talk about pinging, surging & rough running below 3 grand problems in this thread solved by replacing a defective fuel pump. That's worth looking into especially if there have been running changes in the fuel pumps. |

They are talking about replacing the '05 version pump with the new improved '06 version like is in the Uly.
I will try to work in a fuel pressure test, and take a look at the 02 sensor and connection. |

I'd take a look at your plugs too. They seem to foul out pretty easily if started "BMW-style" with a bit of throttle.
Also I had the TPS reset done, and at first the bike seemed no better leaving the dealer. But did seem better after a few miles. |

I dont use any throttle when starting. Airhead beemers needs throttle to start but the FI ones didnt. I let it idle until I have my helmet and gloves on, then take off. |

Just an update. My bike has gone from running poorly, to running OK, to running well.
Not sure what the root cause is. I didn't follow proper science and do these all one at a time for your benefit  . But I thought I'd post all the changes for you to help.
Running poorly - New, front plug fouled and was replaced.
Running OK - 1k service (TPS reset, timing checked). I replaced the rear plug "just in case". Adjusted the idle up a bit.
Running well - @4k mi. I reset the TPS. Cleaned the TB, airbox, and temp sensor of excess oil from breather. And reset the idle.
Now two things I've noticed.
The ECU can control idle speed. And I think there is some relation between the mechanical adjustment, how much the ECU needs to work to correct that, and how the bike runs.
The TB of my bike was covered with a film of oil. The breather coughed some up and it was in the airbox. I cleaned this out with some carb cleaner spray and the bike was idling ~400rpm higher after with no adjustments. I adjusted it back down.
Anyways, if your bike runs poorly, try cleaning out the TB. |

Steven - Thanks for the info. TB is Throttle Body? |

Yes, sorry, specifically the area of the throttle plate.
I somewhat wish I did the cleaning THEN reset the TPS and rode it inbetween. See really where the improvement was. The low end of my bike is drastically better. |

FWIW, I put new tires on the Uly this weekend, and a lot of the issues I thought were related to the fuel injection system are gone.
I'm not sure if I was just mistaken about the source of the problem, or if the original tires amplified the effects of the FI system. |

I know I'm late to this party, but My 12Ss has the exact same issue, and has from the moment I got it. I thought it was just the twitchy throttle to begin with, but after I got used to the sensitivity, I realized there was more involved. Now 5 months later, it's worse than ever. I've taken it to the local dealership, and they told me they couldn't even feel a problem (I know, I bring this up in every post... sorry!).
My exact sypmtoms: a splutter-surge when holding the throttle steady at any RPM, especially from 2000 to 3500. Especially noticeable in lower gears, I think because the gear ratio allows the surge to push the bike around a little more. I haven't made it into the shop again for the TPS reset just yet, but I have high hopes that that will clean it up.
There's no way that this is a normal and expected thing on Buells. I've read every magazine article I can find on the XBs, and 2 things are very clear: 1) The sportbike world likes Buell, but despises the fact they are powered by H-D engines, and 2) Not one of them has mentioned a rough engine at lower rpms.
Now, don't you think those same writers would be jumping on the chance to bash the Harley engine for roughness if they could? I've seen alot of them fuss about the low top end and the fact they're air cooled, but not one has mentioned the problem discussed here. That fact alone tells me it's not NORMAL, just COMMON.

Has anyone with an earlier than 06 model ever had these symptoms?
My 06 Uly doesn't, but I've made so many mods, it isn't a fair comparison.
I have a customer with a Uly that has been having the problem. He's going to swap in an 05 ECM I'm sending him to see if it fixes the problem, or at least changes it. Near as I can tell, the maps didn't change. But I know the ECM config IDs did, and I know there are algorithm changes, I just don't know what they are.
Has anyone that has installed an American Sport Bike open airbox kit exhibited these issues? I'm wondering if it is related to air induction issues. I still can't make any sense of the air induction changes Buell implemented in 06. The intake location makes no sense to me at all. But they're smart guys at Buell, there probably is a reason for it. I just can't figure it out.

Al,
These symptoms have been around since XB12's were released, changing the ecm will generally not help. Fortunately it's a minority of bikes that are affected. Once you've played with fuel on an XB it's easy to hear when they are starving, they still run but don't sound as healthy.

Update
I am either getting used to the surge, or it had diminished as the bike has gotten some miles on it. At 4900 miles. it seems to have smoothed out. I let it warm up longer when starting out, just had to get used to doing that.
It is a great bike, and I love riding it. |

Installed the '05 ECM. No change in the surging, or the fan (run time) characteristics, noted. I have ridden the bike in ambient temps ranging from 60F. to 85F, with no difference noted.
Al, do you think the Dobek Jet Kit that you sell might help this surging? |

>>>My take is that if they don't all do it (which seems to be the case) then by definition something is wrong.
I agree.
You paid for a "right running" motorcycle. The dealer is R-E-S-P-O-N-S-I-B-L-E to ensure that happens.
Simple.
Go back and read the "Court on dealing with dealers" lesson and get with it. If the dealer can't fix it, they have a host of resources through the staff at Buell Customer Service.
These folks have seen it all and have TONS (helps to be the wealthiest motorcycle company in America) resources at their fingertips.
Let me clear....the folks at Customer Service have but one marching order...to SERVE customers....you paid your money, did your part of the deal, ask..politely the dealer to hold up his end of the bargain.
Easy stuff....
Not easy stuff, here's why:
In the automotive world (in which I work) we have a terms for things like this called:
"product characteristic" and "industry standard." (I am not making excuses here for Buell, or any other maker. I am only stating the facts, I deal with daily.)
What that means is: the "problem" or "characteristic" is real, however the vehicle IS operating within the factory design spec.
Do we like this "characteristic"? Probably not; can it be fixed? Maybe.
In the case of the Ulysses surging, it will not be something that a dealer can fix (legally) without a factory design change and a procedure (TSB) that has been certified by the Government.
I believe the surging problem with the Ulysses falls into this area. It is something that, yes, "they all do", but no, they are NOT broken.
I don't like it.
Our options, as owners, are: live with the characteristic, bitch about it (wait for Buell-H/D to come up with a fix) while living with it, or fix it ourselves. |

I think you've hit the nail on the head. Mine was pretty bad new, now with ~6300 on it it's smooth as can be.
I just checked the throtle again today and it wasn't nearly as dirty as before. FWIW. |
