08 uly, Developed a stumble at 4000 rpm and takesoff again at 4500. Plugs , ECM, air cleaner, all are new or ( ECM ) updated. No codes show up. So o2 sensor and or exhaust valve? So far two dealers no fix and I need some advice on what they might look for. Thanks, Rekrab. |

Had a very similar problem. http://www.badweatherbikers.com/buell/messages/384 2/379371.html?1211015522 After working with a guy in Ohio that has hacked the ECM for the 1125 (we share the same ECM) we decided that it is the EPA lean built into the fuel maps. I adjusted the AFV on mine, it went away but developed some other issues, mainly running rich which gave me some undesirable traits at low RPMs. So I hooked back up the O2 sensor and let it relearn itself back into the regular setup. But that's what I would say your issue is. As long as nothing else is acting up anyway. |
