Greetings to everyone!
After just a day of not riding my '2000 FZS 600 developed misfire on 2 and 3 : idle revs are lower, power loss and does not pick up revs like before. It has spark but when removing the cap from cylinder 2 or 3 at idle nothing changes but when from 1 or 4 it dies immediately . I cleaned the carbs (didn't split them, only the jets and diaphragms so the mixture and synchronization settings remained the same) but it did not help. Need to mention that pilot screws are turned more than 2 turns out like the book says, on 3 particularly it looks turned out about all the way and both 2 and 3 were running a bit rich with black ish spark plugs. I never messed them before and rode the bike for 17 thousand km. But when you inject some quick start to carbs 2,3 revs go up a bit but if to 1,4 it just dies.
I am sure I could smell petrol on the spark plug 3 and there's definitely enough gas in float chamber.
Now the electrics: I tried old and new spark plugs, the coil resistance is correct, the plugs boots too, swapping 'new' used coil does nothing.
Maybe someone had a similar problem?
Earlier in the summer a few times after starting it did not run evenly as if on 3 cylinders, but after warming up or at some point it just fixed itself and I thought it was the faulty old plugs.
