Well I just left the dealer and left them my bike for the post rear-ended inspection and to install my new Jardine. The Buell tech told me that changing the pipe was not wise because I was gonna lose all sorts of midrange and low end power. Is that true? I also told him to remove the snorkel which he indicated that this was standard. Is it true that I'm gonna loose all my low end and midrange?

NO......
My Jardine only had a dead spot in it around 2500 RRM everywhere else it rips.

jardine is indeed more of a top end pipe than some others out there,but it is still a good performance increase over the standard pipe,plus its price reflects well against the competition...im more than happy with my jardine,though i can only compare it to the buell race pipe that was on before...above 2500 it pulls hard,and i dont think it suffers too much low down...again there are better performing pipes for low end and mid range power,but i think you will be happy with the sound and performance with the jardine

Best bang for the buck me thinks. I don't spend a lot of time around 2-2500 RPM so it's not that noticeable. IMHO, you'd be luggin' it a bit if you hang out down around there. If you're worried about losing bottom end, I'll refer you to the wisdom a fellow badwebber once told me, "Just drop 2 and WHACK IT!"

If I put a Jardine on my XB12R do I need to do anything else such as ECM or TFI,Is it just "bolt and go"?...John

Euro,

According to the my Buell tech, he states that it is important to at least change the ECM in order to prevent running the engine lean. He told me that it will run lean if you do not change to the race ECM. However, he did not see the real need to change the air filter.

Just the Jardine on my 12s, you do loose some bottom end but theres plenty of GO further up.Plus a real nice sound. Asked the dealer about changing the ECM and he said the 12 was ok with the Jardine, in fact they had taken the Race ECM off their demo bike and just left the filter and Buell Race pipe on.

The best way to check if your rich/lean is to have your bike plugged into the Buell analyser tool. Check the corrective fuel multiplier value. This value is learned based on O2 readings and applied to the fuel injector pulse in both open and closed loop operation. A value of 1.0 mean no correction is being applied. Less than 1 means your fuel pulse is being shortened or leaned out. Greater then 1 means your fuel is being richened over the stock map lookup values. I'm not sure of the valid range (maybe 0.75 to 1.25). If you are running at the max or min value then your ECM cannot compensate any more and you are going to be rich or lean. You will have to take other measures to correct it. If you are within limits you should be fine.

I have a drilled airbox, race filter and race pipe with stock ECM. At 6000' altitude my correction factor is .9 (in range). The ecm is still leaning out the fuel to compensate for the altitude inspite of the mods I have done. Bike runs good and the correction factor make sense to me.

The 12 ECMs handle pipe changes much better then the 9's. A race ECM at this point is an option, but not a neccessity. If your really unsure, have them run it on the Dyno with a sniffer to test the output. Vaughn's method has merit but doesn't account for airflow. The shorter pulse width on the 12 could simply mean your were the valve actuates, and the ECM isn't seeing the increased airflow the valve creates. That won't necessarily make it lean.

I am running a DRUMMER with a stock ECM, running pretty well. very smooth even on cool 27 degree rides t work. tried a race ecm for a while, but it ran very lean, missing and stumbling under cruise conditions. the stocker is behaving itself better.
