uk 03 zx6r b1h ignition cut at speed problem???
Right guys bear with me while I try and explain this. I have an intermittent problem at high revs/speed (typically 9k revs or about 95 mph). What started happening was I would ride along and then all of a sudden it will drop the nose like someone turned the engine off but everything stays on, it's only for a second then it resumes normal service but won't go past that point. Some rides are great and she goes like stink no problems but now iis happening more. I have a racefit exhaust black edition k &n filter and a power commander. At first everyone said check the fuelling so had it dynoed and the fuel and power curve were spot on 112bhp. While she was on the dyno the problem occurred but no Fi light or codes etc so we checked the starter switch, the clutch switch nd the side stand switch. All ok. The guy said it might of been my alarm so I swapped the loom out, still happens same revs and sort of speed etc. Changed the plugs coils and fuel pump. Still no joy. I'm torn between a new ecu or set of throttle bodies but would just like to know if anyone has had this on there's as it's sending me mad now. The bike runs great as I commute daily to work but when I want to press on she don't want to. Any help accepted. Cheers people.
