I guess just because I got my Uly idling well after installing the race ECM and pipe, I thought I had things working properly. Not! I took it around the block and it was as if I only had one cylinder running (which I don't). the lack of power was overwhelming kind of like the timing was severely retarded. Any ideas where I should look? I reset the TPS after the ride with no change. I left the exhaust valve electronics hooked up in the airbox. The control cable to the pipe is gone but does this electronic connection cable need to be disconnected too? Any help appreciated. (Message edited by orangeulius on April 16, 2007) |

Not sure what is going on. The cable being connected shouldnt make any difference. You didnt happen to leave a rag in the intake port? Not sure what to tell you, is it missing like a cylinder isnt firing? Try your old ecm, and see if it still has a lack of power, if so it may be the Race ecm. |

Sounds like the TPS reset wasnt done right. |

I second putting the original ecm back on to verify you don't have something else wrong. When you put the original ecm on you don't have to do a tps reset as it is already set in that ecm. You very well could have a fouled plug especially if the tps reset was done wrong and it was idling bad for a while. To do a tps reset you must back off the idle adjust screw first and make sure the throttle plate is fully closed. Forgive me if you already knew this. Just a couple of ideas that might help. Mark |

Well after reading everyones suggestions I went out and checked my procedure. I wasn't getting the valve closed all the way. I think I got a good reset now. Unfortunately I may have fouled my plugs trying to run it with a bad reset. I'll pull the plugs and play with this some more later in the week. Any suggestions on the best/easist way to remove the plugs? Live and learn. Thx |

I fouled a plug with only a thousand miles on the clock (cold day, started engine, and blipped throttle). Decided to ride home on one cylinder. To my surprise it cleared up about 2 miles down the road when engine warmed up. Road another 4000 miles on that plug without issue. Removing front plug can be done with a wrench just remove air scoop first. To remove rear plug requires removal of airbox base or at least loosen it and slide it sideways then use a plug socket, swivel, and extension. Use a rubber hose pushed over plug to aid in reinstall.

Make sure you did not get the race ecm for a black bike. They are slower than the orange stock ones! |

I did mine without removing the airbox base without problem. A pair of good plug boot pilers or longer fingers helps either way. These are GREAT: http://buy1.snapon.com/catalog/item.asp?P65=&tool= all&item_ID=78286&group_ID=1351&store=snapon-store &dir=catalog |

I replaced the front plug, reset the TPS and took a ride around the block. 3 interesting things happened. Twice the bike surged so quickly it about yanked me off the seat. It felt like someone reconnected whatever was broken. This makes me think I may have yanked a wire somewhere while screwing with the bike. I still feel like I am running on one cylinder. About 3/4 of the way through this 1 mile ride the red engine light came on and stayed on. no error codes. Then the low fuel light came on and stayed on. I have a full tank of gas. Clearly I have yanked, pulled, compromised or otherwise unknowingly broken something. Time to retrace my steps. Oh I also put the stock ECM back on with no difference. Bummer. |

I planned to replace the rear plug today and make sure I had not pulled any wires loose while yanking out the the control wire for the stock pipe. Etennuly stopped by to lend a hand and we found that not only was the rear plug fouled but that I had yanked the rear plug wire off the coil. No wonder it felt like I was riding with only 1 cylinder....I was. Vroom Vroom! Thx Vern! |
