Fazer 1000/FZ1 corner / Cut out on half throttle

Any clever clogs on here because currently, that doesn't include me.[/size]Venerable Fazer Thou had issues with battery,largely through my use of the wrong charger(s) and battery(s).Installed new fully charged battery and during the install I must have left the ignition on because there was a lot of chatter from (I assume) the fuel pump.Fuel pump was not priming at start up but seemed ok on the bench later. Refitted seemed ok.First test ride it wouldn't take anything over 1/4 to 1/2 throttle. It would baulk and splutter then die.Second attempt same thing except this time it blew the 10A fuse.Stripped and inspected pump, tested ok on bench, tested ok on bike, refitted same issue though it never blew another fuse.Fitted new pump which sounds much healthier but the same issue! 1/4 to half throttle and it coughs and dies. Roll off the throttle and it's fine.My first thoughts are fried ECU or perhaps a dodgy EXUP system but I wouldn't expect the EXUP to kill all power then come back and I would expect to see a fault code displayed on start up.Anyone have any other ideas because at the moment, I'm stumped. Going out to have a look at the EXUP and especially the wiring. I really don't want to strip the carbs for fault finding, they are a bastard to get out and I can't see how one carb could develop a fault affecting everything and all four carbs having a mechanical fuel issue is unlikely I would think.Screwd.[/color]
