I have done a search a few times and never found an answer, I am sure I am doing something wrong since I am sure I am not the only person who has had this problem, at lease I hope not-lol.
I have a 2002 x1 and had this issues off and on for years now, and seems to have gotten worse. I am not sure I can explain it correctly, but it seems to lose power or stall as I am riding. the motor doesn't cut out but rather as I throttle up, the engine sort of revs, but the bike loses power.
It isn't constant, it pops up. It happens or doesn't happen in all types of weather, on long or short rides, bike is warmed up. There doesn't seem to have any rhyme or reason to it.
I checked the code and got an O2 code, and changed it, in hopes it was that. It wasn't.
the buell dealer change the ignition modular. that wasn't it. More over they really didn't know what they were doing or talking about.
I have a second question, does any one know where to buy a buell code reader cheap or a universal code read or computer or phone app that works with the buell? I read in the service manual that the o2 code could mean other things are wrong but to figure them out you need a reader so you can check the voltage via the reader, I think while getting the code. I'll have to reread it to make sure. Either way It would be nice to have a code reader in the future.
I appreciate any help I can get on these matters. I am sorry if I have been unclear or re asking a question that has already been discussed.
thanks

ecmspy for your laptop is your friend 
Or ecmdroid for your android phone will do the same but you will need a bluetooth module to plug into your bike with the droid version instead of a cable. |

Thanks, I will look into it, but already disappointed...No Mac version or iphone app. I'll have to barrow a pc or something.

Well, You what you need to do is start from the most simplist basics, such as a basic tune up.
-Plugs
-Wires
-Check your ground strap on the rear swing arm
-And fuel filter.
You need to eliminate if its a fuel delivery issue or an electrical issue. When you get ECMspy up and running, let me know and i'll run you through the installation and how to set it up for what ever version of windows you are running.
----Lucky you, will be benifiting from my prolonged dilema with a similar issue.
Things you may need to pay attention to are your:
-Engine temperature sensor or (CHT)
-Bank angle sensor (BAS)
-Check all your fuses and or replace your fuel pump relay.
Is your a California Buell with a smog canister? If not make sure that your fuel tank vent line is clear and not plugged into the intake. Let me know how all goes, and best of luck. |

Thanks MrSandman, I ordered the cable for ECMspy but won't get here for about a month. That will give me a chance to work out a computer and give the bike a once over. I've been ill so I haven't ridden her in a while so she needs some tlc so looks like I'll be busy with that while I wait for the cable.
Its a Cali bike but I took the Canister off a while ago so I'll be checking the vent tube.

The head temp sensor can cause really odd issues.
Cheap to switch out ($35?), plus you don't need to recalibrate for the temp sensor.
ECM Spy will tell you right away if it the temp sensor. |

BLUM2 is correct a buggered CHT can cause some funky issues. But as a said earlier, do a basic over haul and see what happens.
But I have a hunch that what may be happening is that your getting an AFV drop. Often times a new O2 sensor and a TPS reset otta do the trick. I would definately change out the o2 sensor as part of your basic overhaul. Best of luck. |

I haven't had a chance to look at the buell, busy with other projects, never ending. waiting for the cable to arrive to do a TPS reset and the o2 sensor is newish, it was the first thing I replaced when I got the o2 code. I hope to have time this coming week to check the grounding strap and the other items mentioned.
I came across an old palm m515, but doubt I can come across a cable to connect it to the buell. it would be nice to have a back up that is easy to carry rather than relay on friends laptops.
Curios as to where you guys get your parts from? Not very happy with the oakland shop. how's SJ's harely shop? |

I am having the same exact symtoms as newbie. Ive gone through and checked all the electrical connections, fuses, and spark plugs. Now I have ECMspy and a cable but it doest give any trouble codes. Im lost? |

The cam position sensor doesn't throw codes when it fails, and can cause your symptoms. |

I installed a new engine temperature sensor and did a TPS reset as well as set the AFV to 100, was at 140. The bike is running great with no problems. Although, when I did the TPS reset the most I get at WOT is 97%???? |
Mrsandman

Hmmm, I never had a problem with the WOT, especially being at 97. Im assuming the bike is running ok as of now? Just to be sure ride it around for a while and make sure the AFV stays between 90 and 110. |

Yeah the bike is actually running great!! Throttle response is way better than it was and it seemed to lower the rpms a little. I normally cruise at 80 in 5th and rpms before we're at about 4100-4200 now it sits about 388-3900 in 5th. |

Glad to hear, happy riding. As always let us know if you need anything else. |

Ok, got the cable and hooked it up, had issues getting it to work, but I think I have it going now, nothing jump out at me soooo if you can explain how to do a TPS reset, I'll start there. also can you give me an idea so to what to look for, and what are some setting should be, so I can see if anything jumps out as being wrong.
like, how would I know if its the temp sensor?
or if its a dropping AFV?
Oh I checked the grounding strap and fuses
and there were no codes according to ECMspy.
again not sure if I have ECMspy working right, I blipped the throttled and there was no changes. |

It is easier to see the TPS reset video on youtube. "Buell TPS reset" all the info is there.
AFV should be on the top right part of the screen when you have ECM spy running with your bike running.
No codes will pop up for any grounding strap issues or fuse issues. You just need to keep an eye on your voltage which should be about 12 volts. Somebody can cross check me but there are no trouble codes for a faulty ETS as well.
You can also get a better idea of many of your engine paremeters by clicking ECM runtime. There are a few acrynoyms that can be fuzzy, but the buell manuel can assist you on that.
Also very important, click on EXTRAs on the top and there is some literature on how this ECM works that is a MUST READ. you will be a bit behind if not.
Check your AFV and we can go from there. |

the sage continues-more like the folies
I connected to the computer, thought the program was working-but it wasn't due to my error. I chicked tps reset but didn't do the other porcedures due to the fact I didn't know how to work the program....the bike could not idle.
then the next day figured out how to get the bike and computer connected and program working....try to do the tps re set again and some how broke the cable...spend the rest of the day fixing that, or should I say a buddy did, reconnected the cable with knob...otherwise I would still be sitting next to my bike in tears...lol.
well try to do the tps reset but the bike wouldn't ilde so we back the screw down to 2.7 or there about so the bike would idle adjusted so it would idle between 1050-1150 went for a ride, and the bike ran like shit, like its on one cyclinder
recheck the wires and plugs, everything good..running a bit rich but otherwise good
so not sure what I did wrong excep everything...lol |

ok ok I had a better day!! I re did the tps reset and this time snapped the throttle close a few times after turning the idle adjustment scew counter clock wise and before hitting the reset button, and the bike preformed like normal, so I finished that, I can't ride the bike right now, so not sure if that was all that was wrong or if I have other issues, but when I am able to ride again I'll see how it goes. |

Glad to hear you got it working. This is a generic video I used. The manuel specifies a similar way but with a different computer.

hi all , i ride a 03 xb9 , after 6-10 miles
the bike pops/back fires & stalls.
it starts up after 10-15 minutes and the same cycle over again.
i changed gas & filter , oil & filter & plugs
no luck. any tips to get me back on the road ?? |

The gas tank vent valve may be blocked or stuck closed. This condition can create a partial vacuum in the tank which can stall the fuel pump, creating an out-of-gas situation.
In order to isolate this as a cause, try slightly opening the gas tank filler cap when it starts to stall again. If it recovers instantly by letting air into the tank, you've likely found something to zero in on and fix.
If you need a key to open the filler cap, use your spare key. |

Could be the cam position sensor. Can you get access to an oscilloscope? What does the tach do when the bike dies? |
Bruinsbuell
| | Posted on Tuesday, September 03, 2013 - 09:20 am: |

the tach jumps 2-3 times then stalls.
it will start up in 10 minutes or so.
and seem fine for mile or so then same cycle over again .... |

The scope would tell you for sure, but it sure sounds like a cam position sensor to me. I bet it backfires also. |
