Had a similar thing happen to my 2008 11k miles fz1 a couple of weeks back first time out since Nov. it was running great for the first 2/3 miles then dropped on to 3 cylinders at low revs then 2 cylinders get the revs up fired on all 4 and ran perfect for a half a minute or so then back to 3 cylinders then 2 aborted ride. Like you I suspected the stick coils but started by changing the plugs (didn't know how to test stick coils or I would have) changed the plugs (NGK CR9EK earwig tail shape) took it out for a quick test ride no problems done approx. 300miles since runs perfect.
