2007 FZ-1 intermittent mis fire

Hello hoping some one can give me some help with this problem. I have read other mis fire threads, and tried the things on them but still no joy.
the bike runs fine, and then will go on to 3 cylinders, before this happens I notice smoke out the exhaust, and when it goes on to the 3 cylinders it drinks fuel. park the bike up and come back the next day and it is fine, runs on all 4 cylinders, no smoke and normal fuel use, and it will be good for anything from 150 miles, and will then do the same.
I have put new plugs in, new coil sticks, checked all fuel lines, all hoses to the MAP sensor look good, cleaned all connectors.
I can't see any fault codes on the dash.
any ideas are very welcome
