I've never seen any smoke from either of mine. |

I get a slow trail of smoke out of my cars oil filler tube, but never seen any from the buell. |

That is by I thought. Maybe I'll have to do q compression test to see why there is blow by. |

the tech told me the same thing bout my bike! that there is a hesitation and its just the way it is! they put a new flywheel,stator,02 sensors, plugs,fuel pump and fuel rail sensor on it!
they told me to put the pipe, race ecm and k&n filter back on it! you can really feel it now! its like a lean misfire, but mine does it between 5&6 thousand steady rpm!
but if u twist the throttle it gets up and goes! so i disconnected my 02 sensors to c what happens! the bike doesnt pop nearly as much and it seems to be alot quieter!
im putting it on the dyno in a couple of weeks to c if we can figure something out! maybe a power comander with a auto tune! im gonna ride it to dover on fri 13th with them disconnected to c if it improves any! ill let ya know if any thing changes! |

Don't use intake cleaner to check for intake seal air leaks! Propane or Mapp gas.
Are you certain you do not have an exhaust leak? Plug the exhaust and check.
Just because a part is replaced with a new one doesn't ALWAYS mean the part is functional out of the box! And, on that thought, you did find water in your spark plug hole. That will fry the coil pack. I'd check to find out why you continue to see water there. Is it possible that your wiring leads water to that spot?
I see nothing about a TPS reset in this thread. Has that been done?
Another thing. Have you checked your voltage regulator and made sure that is operating properly? |

I have used Propane around the intakes, no change in running. I was also told to check the vacume line to the clutch. It seems to have vacume to it. I'll have to tear it down to look further.
As for the exhaust leak, this problem happens with both exhausts on, and I listened for leaks with a stethoscope and nothing. There is also no carbon tracing from the manifolds on the heads.
I think I may check the timing chain guides as there seems to be a few people with that problem.
TPS reset was done about a million times...okay maybe not that many but you get the point.
I haven't checked for water in the front coil since I've replaced the front spark plug. And I haven't ridden in the rain. However that wouldn't hurt to check again. it just involves rotating the engine. |

Well, after a couple of weeks of reading threads when I had time and talking to people, I decided to follow the advise I read on another thread. I unplugged my O2's and installed my baker exhaust and ecm.
the jerkiness and hesitation, and all other running problems went away. I rode it for 220 km's like that and it ran great!!
So as a control, I plugged the O2's back in and it reverts back to it's old ways.
Should I just keep the O2's unplugged? Why isn't the CEL coming on with the O2's unplugged? |

So, there may be a lean condition going on.
When you have the O2 sensor plugged in, what are your AFV's reading? |

If he's using the Race ECM then I think AFVs remain at 100 don't they? With that being said, if it runs better with the O2's disconnected and the AFV's locked at 100 then it doesn't sound like the engine "needs" have strayed very far away from base. This makes me think the O2's are the buzz kill of the party by feeding back bad data to the ECM for short term corrections. Race ECM may be a different story, but seems odd though that the stock ECM wouldn't pick up on a bad O2 since it has fault codes for always rich, always lean, or completely inactive. I suppose it's plausible that a lazy O2 could cause problems while staying outside of those fault code parameters?
I guess at this point I'd be inclined to replace the O2's since they are fairly cheap. If that doesn't work then you always have a plan B by disconnecting them. After all, you only have so much hair to pull out :-)
Way to stay after it though! |

"If that doesn't work then you always have a plan B by disconnecting them. After all, you only have so much hair to pull out :-) "
How true how true.
When I did a long ride with my stock ecm my afv's were just a hair above 100, and with in one or 2 points of each other. And yes the race ecm reads afv's. I'm not sure if it does in open loop though.
I was thinking the O2's as well, but could it also be the map or mass sensor, what ever this model uses? Can anyone tell me if the temperature sensor on the air snorkel is also a mass, and if so, how is this sensor "clocked" in your snorkel.
Thanks

The temp sensor in the snorkel is just a temp sensor. I don't think disconnecting the O2's would put it in a "Limp Home" mode so all other sensor should still provide similar corrections for both test cases. That's why I was leaning toward just the O2's since it's the only variable you changed in your last test.
I do know these bikes don't have a MAF sensor but instead use MAP, TPS,and RPM as some sort of speed/density & N-Alpha variant. |
