XB12s Help!!

[juetat2]

Hi all,

Im new here so hello everyone. Hope you are all well.

So if you could bare with me while i try to explain. I have had my 2010 buellxb12s for maybe 2 years now. Ive always found it to run a little inconsistent around 3000rpm but I found i could live with this, then about 6 months ago I bout a EBR ECM for the Jardine. After installing it ran differently and better once i got going and flying through the gears.

So what I have noticed though is, It feels like the bike is gulping too much air or something in low rpm. For example, if i coast along the street at say 20mph with the clutch in and give the throttle a quick twist it kinda bogs down and sometimes feels like its about to cut out, a few seconds later the rpm with go back to normal.

Has anyone had this before?... Its plagued me for solo long. It used to do it before I had the EBR ECM but now its a lot worse, otherwise the bike seems fine.

Any similar experiances/advice would be much appreciated.

THANK YOU!!!!!! ALL!!!!!!!! ..... ps, i love my buell.

Do you have ECMSPY? It could be that the bike is running a tad too rich or a tad too lean around that rpm range and throttle position. You can compare the two maps (stock and ebr) to see if at that rpm/tp you are now richer/leaner and manually bring the value back to where it was.

FYI EBR themselves recommend not using spy cable on race ECM. Coding is different...

oh...carry on then

My bike kinda falls on its face a bit if I try to blip the throttle like the jap bikes but I don't consider it bad at all. I thought the ebr ECM was sapossed to fix or make better of those things? I plan on getting one this spring and hope its money well spent so I do not have to try and tune it myself.

Sounds same as my xb9 with a d&d, it was loping (sounded like a dead cylinder)at 2500 to 3000rpm with a race map, I programmed it with a map someone had for a Jardine/ K&N. The 3d view showed more fuel in a much broader range. It was running better but still had some lope, I tweaked it by adding more fuel, especially in the rear cylinder.

Thanks people... I'm still not too sure what to do???

Don't blip the throttle from idle. Problem solved.
