Hello I have a 2 week old xb9r at 290 mi I installed the race kit(muffler,ecm,filter) and the bike ran terrible. I took to the dealer and had the tps reset, they wrote it up as a download. The bike does not idle when cold and spits and coughs( like back firing through the intake) until it gets hot and then idles at 1000rpm but the throttle has a very slight dead spot or hesitation when the throttle is slightly pulled past the closed position. Before the race kit and the tps reset the bike would idle when cold and didn't spit and cough. What could it be? |

Have you taken it for a ride of any significant duration? The adaptive fuel value (AFV) may need to self calibrate. That requires a warm engine and 5 miles or so of moderate rpm riding.
If that doesn't bring things back to running properly, your TPS reset was probably not done properly. Also they should probably set the AFV to 100. |

Jim - do they guys at the dealership know you as "tampax"? |

Since I had the race kit installed, I havent had any cold start or idle problems but what you say about the "dead spot" rings a bell. I get mine at around 2000-2500rpm when riding with just a little bit of throttle. Almost seems like a stumble. In the latest Fuell, there is an article about TPS and it seems like that is one indication of needing to be reset. When I get my spring (whenever that may be!) oil change, I'll see if they can re-do the TPS. Anyway, long story short, Tampaxb9r, that would be the first thing I tried. |

Well, I've put it off but now the Bolt HAS to go in to the dealer. The "stumble" around 2200 rpm is now from around 1800 to 2600 rpm. Almost like its missing. Sounds like crap! Final straw is now when I come to a stop, it wants to shut off and if it does, it's a b*tch to get started. Something is definately wrong. Keep ya posted. Any luck with yours, Tampaxb9r? |

Definitely sounds like you need a TPS reset. |

Well, here we are. Nine days after I took the Bolt in, I finally go to pick it up. Verdict: "there is nothing wrong with your bike"! "By putting the race kit on, you moved the power band to over 3000rpm's." "Only thing you can do is to stay out of the 1800-2400rpm range whenever you can" Yes, these are actual quotes! Does anyone else with the race ECM have this problem? Spitting, missing, sputtering with throttle just off idle, almost coasting but giving a little gas. Do I take it to another dealer and specifically ask for a TPS reset? I know one thing for sure, it will NEVER go back to the "dealer of the year"! |

Paroyboy - Did they charge you? Can you get names and have people sign off on that answer? If they screw you hold them accountable.
Is that an actual result of the race kit? Anyone else have this problem? Seems like a very poor product for any type of street use if that is the case. |

It is true that you should not be riding around at under 2,500 rpm. But the symptoms you describe point head on to a bad TPS reset or other DDFI malfunction. Which dealer was that? |

My 9R with Race Kit is jittery or jumpy at slow speeds.
It doesn't cough or sputter like a carb fart on the CV equipped bikes, but definately not smooth like the stock ecm and muffler that came on the bike from the factory.
I wonder if my TPS isn't set right.
Mine was the first one the two nearest Buell dealers had done. I took it to a different dealer to have them try and set it as it didn't seem right to me either.
Finally ended up taking it back to the dealer where I bought it. They had another two attempts to get it at where it's at now. They claim that they replaced the ECM, but I still believe it could be set up better.
I bet Buell looks at the service profile of my bike and wonders why it's been to two different dealers on 4 occasions to have a TPS done.
It runs like a banshee above 3k.

Hey! and I thought I was the only one with this problem...My dealer (good friends mind you) is trying to gaslight me by telling me that they all run like that - hmmm, don't think so.
I've asked for a TPS reset twice, and they say it's fine - I think they just checked, not RESET the TPS. I believe if the TPS is not set correctly in the first place, all subsequent checks will reveal no problems.
Ok, so if the low RPM problem (mine extends to 3100RPM, BTW) is the race ECM, how will the bike run with the stock ECM & intake but with the race exhaust? Anyone try this?

Paroyboy, ask your dealer if he checked the Adaptive Fuel Value. If he says, "Huh?", take it to a dealer who has a clue.
If the AFV reads some value other than 100%, he should have reset it to 100% with the Scanalyzer. This can correct an overly lean or rich condition if all the other sensors check OK.

Yeah, I paid for them to tell me nothing was wrong! (only about $20 though) I think I will call the dealer in Harrisburg (same distance) to set up my wheel bearing appointment. I'll see if they will check the TPS and AFV without giving me a ration of sh*t!. I am definately done with Battlefield HD. |

i have a 9s with racekit and absolutely no problems!? the bike runs GREAT. low and high rpm's. so i would also guess that the tps resets have not been done correctly... |

Paroboy,
Anyone who knows how this system works will not just arbitrarily reset the AFV. It is a learned value and should be left alone.
The AFV is an ADAPTIVE FUEL VALUE and is changed according to the engine's needs. 100% will rarely be found on an operating motorcycle on the streets.
Go to your dealer and have them contact technical service for help if they need it. |

Took the Bolt in for the wheel bearing replacements today. Told the new dealership the problems I was having in the low RPM range and that the old dealer said it was normal for the race kit. She looked at me as if to say, "You've got to be kidding"! She mentioned a possible intake leak or, get this...."a bad TPS reset"! The clouds opened up, light shown down, the angels sang....etc! Hopefully, the mechanic will be as helpful/knowlegable as the service writer! Let ya know... |

Paroyboy,
as you know I have a race kit on my XB. the first two days it ran shitty below 3000 and I even fouled a plug and ran on one cyl for a few miles.
I took the bike out on Rt 83 ran ran it for about 10 miles above 3000 rpm when the engine was at operating temp. now the bike runs great, no jitter, no dead spot and runs great below 3000 rpms. if your bike is not running right there is something wrong. The XB F.I. system is the best to date and should run great with the race kit. |

I've got a kitted XB9R with the same problem. The bike is very jittery below 3000rpms and it's been so long since I had the stock stuff on it that I can't remember whether it did it then or not. I've had the TPS reset several times since the race kit was installed, tried the whole engine warm run at 4000rpms to reset the AFV - nothing works. Fortunately I don't like having the bike that low in the revs anyways. 3500-4500 is where I cruise, that way when I hit the throttle it just GOES.
I do need to call my dealership about the wheel bearing replacement as well before the NE tour. Unfortunately they will probably stick me with that damned sidestand (no, I never got it replaced). Have they solved that one yet? When I was in Deal's Gap one of the guys with a bolt had the new sidestand just snap right off while it was sitting at rest.

to all! a race kitted XB9R/S should run great from zero to redline, period! if the dealer or service writer tells you different DEMAND them to call Buell technical service for help. |

Well, I got the call today that the bike was ready. Unfortunately, we were in the woods clearing for the new house so I didnt get the message until after the dealer was closed. Guess I'll pick it up monday if the weather holds, which it probably wont! As it is, we're three weeks behind schedule for the house! You have no idea what hassles are until you decide to build a house in the middle of nowhere! Could have bought a house ready-made in a development but nooooo! Enough whining for now! :-) Let you know monday how the bike is. Later |

Two_Buells:
Mine runs just as Bryan describes.
I've read it from others too.
Maybe the dealers are correct? Or perhaps Buell needs to remap the curves?
I dunno. I just cringe at the thought of asking my dealer to mess with it again, since they had so much trouble getting it to where it's at now. They've been extremely patient with it so far, and have gone out of their way to keep me happy.
Could it be that they are using the LapTop PC/Software to do the TPS instead of the hand held Digital Technician?

Never had the "stock kit" so I don't know how it compares, and I haven't seen any troubles at all. I always warm the bike at idle for as long as it takes to put on my jacket, gloves and helmet. I also don't notice a "big flat spot" either people have talked about. I hope ya'll get this sorted out, for this is a most excellent bike from idle to red line. Mines an '03 XB9S. |

FWIW,
After installing the race kit, my bike ('03 XB9R) was not happy. It didn't want to idle and didn't run well at low RPM's (below 3,000 RPM). It also wanted to "surge" when giving it gentle throttle input. Also, these probs were worse when the bike was cold.
A trip to the dealer to get the TPS reset cured these ills. The bike idles fine and is very smooth from idle to redline since doing so.
The tech at Glendale Buell was very careful to make sure everything was done according to factory procedure. I had the benefit of being able to stand there and watch him do it, as he checked and re-checked to make sure everything was correct. I'm very happy with the results. Especially since reading the remarks of some of the others here who seem to be having similar probs even after the TPS reset.
So, I tend to agree with Two_Buells, that it ought to run fine through the entire RPM range.
Knowing how much of a difference it made to my bike, I would suggest giving it (TPS reset) another try at the dealer.

noface,
DEMAND your dealer to call Buell technical service for help. You should not put up with a bad running bike.
My dealer hated me when I keep bringing my 1999 S3 (first year for F.I. on Buells) in to get the F.I. problems fixed. |

Well, picked the bike up today. They told me the same thing. "No bike with a race kit on will run smoothly at lower RPMs" "Two of our techs tried it out and said it is running as it should". I am about ready to throw in the Buell towel! (I did mention before I'm not patient, didnt I?)At least they didnt charge me for their words of wisdom. I have another month until my year is up on the bike. Sprint ST? FJR? Yeah, I'm babbling. I might try one other dealer. I will just ask them point blank to reset the TPS. I'm even willing to pay the 1/2 hour labor to do it. Then, if it still runs the way it does now, I'll agree with them and off load it. On a good note, I did get the wheel bearings changed! Later |

I'm told by our service manager here at work (Harley/Buell dealer) that a software upgrade was issued recently and two steps in resetting the TPS have changed: I believe that you say, "OK" instead of punching in the values manually and the digital technician resets the TPS and AFV values.
I could have the details wrong as I wasn't there when it was done on my XB9R but ask your shop to contact Buell for the revised procedure. |

I wonder when each of these bikes were manufactured? Mine was a relatively early 9R (June '02 is the date on the frame). Has something changed in the ECMs between now and then?
In any event, I believe that I will ask Motor City (the dealership my bike is at right now for the wheel bearings) to do a TPS reset on it before I pick it up. Provided they don't want to charge me all that much. ::growls::

I got my 1K service last week, and it seems like they got the TPS reset much closer to right. Still not perfect (stumble under 2.5K), but much better now. I'm going back in at some point soon to try the new reset procedure to see if we can make it perfect.

SUCCESS! Had the TPS reset this morning. Told the write up guy how it was acting. He seemed to agree the TPS might be the problem. They did the reset then took it for a test ride. (side note: this is the first time I heard someone else riding my bike. The Buell race muffler sounds pretty damn good!) I don't think the hesitation, stumble problem is completely gone but it feels a hell of a lot better than before the reset. Might just hang onto it after all! |

I've had these same symptoms. Dealer determined that it was the Bank Angle Sensor, which shut the fuel pump off. This happens if the bike falls over. The bike would kinda lull and stutter. When I would come to a stop it would flat out stall, and it was a bitch to restart. First thing i thought was a TPS reset (no aftermarket exhaust or racing ECM), but that didn't work. The dealer also found that the Temp sensor was bad also. Just a heads up as this maybe your problem. |

I am in france and have an xb9r, added the KN and customed the stock exhaust, it sounds great, I also have a spare stock ecm which I would like to flash but need some sort of prodedure...I have a computer and skills to make it happen, but question is what software do I need, where do I get the maps from, and does anyone have a wiring diagram to hook up .
Thnx |

My bike started acting up in traffic. So I figured it was the o2 and ordered a new one. IT may be my TPS. How does the TPS get mis aligned? I have a PC3 installed btw. |
