Problem solved! Sprocketcenter has part number 21805 listed for the fz8. I cross referenced that with the afam catalog and found that part number to be a sprocket for an R1. Our part number is 21607. Such incompetence is inexcusable in my book and I can't wait for them to open Monday so I can call and chew some ass! Ordered the correct part from Blue Streak Racing. Nice dude to deal with on the phone.
