Hi all,
2007 XB9R. I recently installed a new fuel pump, fuel filter and sock (I used the DIY fix found here; http://www.buellxb.com/Buell-XB-Forum/Buell-Firebolt-XB12-XB9/DIY-Fuel-pump-fix.-Cheaper-than-replacement-from-HD
I also had a buddy put in new spark plugs. They were the NGK iridiums and they were not gapped upon installation, they are running on factory gap. The issue I'm having: bike will not run/idle without the AFV set to 140+. TPS reset does not help- TPS voltage is smooth and consistent when pulling on throttle. I also have to set my idle adjustment a bit higher than normal for the bike to idle above 1000rpm.
When the bike is running, there is a loss of power between 3800-5000rpm. The bike also bogs down/hesitates at 4000-4600rpm, it won't run smooth at all in this range.
Problems occurred immediately after the fuel pump/oil/sparkplug change. I thought the O2 sensor might be going haywire so I replaced it. No change.
I am wondering if something post-pump install clogged the injectors, or if the airtex pump that was installed is causing issues. The airtex pump spec sheet claims it can push 90psi. I know the walbro pushes something around 45-50psi. Could this be an issue?
I run race maps since I have the drummer and K&N. Burning the stock maps back on makes the bike run even worse.
Any ideas? My next plan of action is to buy a walbro 521, and replace the airtex that is currently installed (unless you guys think the airtex should be fine). I am also looking for the fuel injector part #'s, if anyone knows what will work that would be much appreciated!
