HELLO ALL, and thank you for taking the time to read.
I have a 2003 Buell XB9S, all stock. About a month ago I wrecked it and did some damage to the primary cover. Saved up some money, bought a new cover, all new gaskets, fluid, etc. Installed them all with no problems.
Rode it to work for two days, then on my way home (about a 30 mile round trip) close to home actually (so the bike was well warmed up) I accelerated from a stop, and the bike missed at mid to high throttle.
I got home, and my neighbor actually smelt the gas. So I smelled the oil, and it smelled like gas. Changed the oil and filter, no film of gasoline on top of the old oil. I hadn't reset the TPS in a good long while.
Put fresh oil in, then let it sit for a week while I waited on a front tire (I noticed the front tire was looking weathered).
Got the tire in, put it on and went for a 10 mile ride, it was doing pretty much the same thing, and getting worse. I got to my destination but the bike wouldn't get me back home. Had some tools and took the front spark plug out, and it was black and carbonized. Put a spare plug in, and it still ran bad.
Got it back home took the rear plug out and it was just as bad. Put two new plugs in, and new wires, tested the resistance of the coil and compared it to a known good coil, and it checked out alright. Also put some fuel system cleaner in it.
With new plugs in it ran great for about 50 miles, then it started to slowly degrade again. I redid the TPS, and may I say the idle adjustment spring is a terrible design (I snapped the cable), and now I just don't know where to go.
The bike is definitely running rich, but why!? |

I bought my '00 X1 Lightning from a shop and it was running like that.
Discovered the the Engine Temperature Sensor was bad. Changed the 02 Sensor at that time also.
Have you checked the diagnostic trouble codes, or DTS as they are known?
Another area to check is your fuse box and ECM. Ensure that all the pins are seated in the backside of the fusebox and the ECM connectors. That spill may have unseated something.

Haven't seen any trouble codes, I am using ECMSpy and I looked under trouble codes, and didn't see anything. I did diagnostics but I don't believe there is a place to test the TS, although looking in the manual I see there are ways to test both. Did you try doing that? I will be looking into getting some new sensors, see if the dealer here has them in. |

Sorry to hear you dropped your bike; glad you are OK. Another vote here for a bad ETS sensor. They can go wonky and not show a code, especially if they 'shift calibration', sending the ECM bad data, skewing the mixture towards rich. |

Well I just tried running it down the street, and I didn't get a block before it started missing and smelling wicked rich. My EGO value in closed loop was really fickle, going from 0.06 - 0.79 V. Then when I set open loop idle, the value dropped down to 0.09 and slowly rose to 0.29 (when bike was reading 180*C. Does the temperature sensor input into the EGO? |

Thanks for the responses! I just ordered the TS and O2 sensors from American Sport Bike. Now I suppose I just wait and see. |

Well I got the TS in on Friday, rode it around for 26 miles in the dark, otherwise I would've gone further, it ran like a champ. Took it to work, it was nice this morning, and my check engine lamp came on, then went off for the entire ride. It was still running fine so I got to work and checked the code. Fan code, fuse was blown. Put in a new fuse and waited until I got done with work, rode it home, no check engine light. When the bike got up to operating temperature it started to act up again, only at 2500 RPM. When pulling onto my street I revved it up to around 4000 RPM and it missed there. Parked it, looked at the fan fuse, and it was blown again. Got the computer connected to it, ran it until it got warm, put it in idle closed loop, and my EGO value was better jumping from .09-.2 to. 5-.7 V. Got it warm ran it up and down the street, and it seemed fine, but why the fan fuse now, I look at all the wiring I could see and I don't see any rubbed/exposed insulator/conductor. Any ideas? |

So yeah... I'm blind. I ended up finding a few bare wires that go to the ECM, one of them was a ground, so I doubt that caused any problems, one was to the "data sensor"(?), and one was to the angle cutoff sensor. Fixed those, and it ran terribly. I finally put the new O2 sensor in and now everything is good, I have put over 100 miles on it and I'm finally comfortable with it. Thank you both again for your words of wisdom! |
