I have this little problem. My FZ1 was running rough, slight surging-like feel but after warm up at least idled somewhat OK. I then changed plugs (four new CR9E's)...there were 4 CR9EK's in the bike???? installed by previous owner. Anyway, now it won't idle hardly at all, surges up and down between 1000 and 1500 rpm at idle...very poor throttle response, almost dies if I don't ride the clutch to get going...seems to be a little better when I get to higher RPM's, but still runs like it is on 3 cylinders...not 4. The previous plugs looked like they may possibly be oil fouled....dark oily ring around the base of the plugs but electrodes looked fairly clean. I rechecked the wiring and they are all to the proper plug. Gapping rechecked and at 0.0028in (per spec's). I'm inclined to believe its either cylinder 2 or 3 (inside one(s) that is not firing properly since I pulled the wiring on 1 and 4 and the bike basically died at idle. Anyone ever have something like this occur with their FZ1? Should I readjust carbs?...if so, what's the best and easiest way to reset for proper mixture? Do wiring sets go on these models or coils? I'm not an electrician so I need some guidance from those in the know. Any help or suggestions is greatly appreciated. I love this bike and want to get it back out on the road ASAP!!!! Thanks for all the help everybody.
