Thanks you for all the suggestions guys. I ordered a set of ignition coils from eBay they came off a 2006 model but look almost new. Put them in and what do you know running sweet again.
That is strange. I have put another 20 miles on the bike and still the problem is there. I haven't washed it for about 2 weeks.
A mechanic suggested it may be the coil caps. It they are slightly corroded they can ark against the head. But I have covered them in silicon spray and it still persists.
I have changed the fuel and taken it for a ride to clear out the old fuel, but still the same problem. I check for error codes. And non there. Not really sure where to go from here.
How do I get it into the diagnostic mode? I have a service manual on disc will have to seen if it has codes. Thanks for all the suggestions. Will try them on tuesday Or tomorrow evening.
The fuel line is fine, and all the headers seem to be getting hot. couldn't tell any difference when I sprayed water on them!
i have put the old plugs back in and still the same problem.
My FZ1 is a 2008 reg. this morning it started to idle weirdly and it didn't have power when acceleration till it hit higher revs. sounds like it is dropping at least 1 cylinder.
I have recently changed all the spark plugs i check them all and tightened them but same issue.
So I don't know if...
