Hi all,
I have a 2003 Fazer 1000 with 14k on the clock. It had some light cosmetic damage and had been stood about six months. The bikes exup was a little sticky when I got it. It's got a full service history. Since repairing it I have serviced the bike, fitted Ivan's full Monty, iridium plugs,pipercross air filter, modified air box and manifold rubbers, balanced carbs, serviced exup. The bike also got new coils as it was running on three cylinders. The bike has an issue with stuttering really badly at around 2500 to 3500 rpm almost clears by 4000rpm and then takes off like a scalded cat. If you go from a standing start and nail the throttle the problem doesn't show but anywhere in those revs if you crack the throttle the bike almost dies. I have had the carbs out three times now, checked fuel, used fuel additives, checked plugs, checked exup valve and cables, checked fuel hoses and filters, checked breathers and anything else which might normally be an issue. The problem still persists! It's driving me insane. Is there anyone out there who could point me in the right direction?
