Buell race ECM, Jardine problems?

[jgxb9r]

I have a 2006 Buell xb9r with a new air filter, race ECM, and a Jardine exhaust. the problem is, if it is a problem is that the power kind of craps out a bit around 4500 rpm, it pulls strong at first, then slows up then pulls really well, any advice/ answers would be appreciated.

Sounds normal to me. My bike acted the same way after I did the race kit.

I have the same set up on my bike. Mine likes to stall out on some cold starts, and on some hot restarts. takes a couple minits of riding to get it to smarten up. idles at spec when at opperating temp.the thing also back fires/pops loud/lots on decel. don't know if i got fueling problems(low fuel pressure?) or an issue with my Ecm. any ideas

things to do:
1) reset tps
2) do a good learning in run (atleast 10k at steady speed)
you want that power-drop gone, get a torque kit fitted. bye bye power-drop, but you will lose about 10% of your top speed.
but the bike will be more powerfull at low-end and straight through the powercurve.

this is only when doing hard acceleration?
that's typical and one of the fun things of a jardine. it's perfectly normal!
also, always let your bike get warm enough before running full throttle or hard acceleration.
best is to start the bike before and enjoy the sound while putting on your gear...

when everthing is ok, a stall can happen, but can be avoided. so if you have it all the time and you really need to do an effort to keep it running, you have a problem.

don't keep pumping the throttle, just let the bike start and keep off the throttle for a minute.
let'm taste the fuel before pooring it in

try this and see if you still have the problem.
