Both OEM part numbers now listed NLA in factory parts system.
Part number as follows if you care to search the net: P0786.02A8
Part number was for matched F&R pair and original list of $329.80
Try a local injector cleaning service in your area or fuelinjectorconnection.com as they're highly recommended
Also recently mentioned on here by a few board members was a one-man-band fuel injector cleaning outfit that was purported to be excellent, though I don't recall the name.
NOTE: All readily available Bosch supplied BMW R1150 series injectors will cross-over to your 2003 only...but a tiny amount of material must be removed from injector feed shaft for it to properly seat in the Buell assembly. But can easily be done.
