Injector assembly from a 2006 with 52k miles. Fits 1800A, 1800B and BD F6B, 1800C Valkyrie. The bike was running great, last trip on the road was 4K miles, came back with a blow tranny, engine parted down. (The last digit in the title before the part number is simply an indicator of originally 6 of them for sale, not related to the placement: they each and all fit any cyclinder-placement on the rail.) The seals, both upper and lower are good, but I personally would not place a good injector without spending the $10 for new seals.
