Hello all,
My FZS 600 has developed a misfire at idle and speeds below about 3500(ish) rpm. Above that it pulls well and runs as normal. It's not always present, but usually is. It's usually present when starting from cold, and sometimes goes away after a run, but not always. When it's misfiring it smells of unburnt fuel from the exhaust. I whipped out the spark plugs this evening (new a couple of months ago) and 2 and 3 are quite black and sooty, whereas 1 and 4 look fine.
Is this likely to point to a faulty coil pack, or is there another more likely candidate? I will check the coil with a meter at the weekend.
Of course whilst poking around and investigating the fuel tap started leaking, so thats another job! :rolleyes
Cheers for any help!
