Miss Fire

[Hammy]

hi guys got a miss fire bike been laying a year started but bad miss fire on revs first thing i done was check tea bag filter was ok
i noticed it was not heating cylinder 2 as mush as the rest so i swapped the coil packs around and still the same new plugs tho
after a bit if ticking over etc they looked a bit black cleaned them still the same also checked the air filter and connections into fuel raid etc

any other things to check some thoughts to mybe the crank position sensor ? tho is there a way to test it and there are no f1 faults showing

Is the plug on No 2 cylinder getting wet with fuel on it? If not, may be a blocked injector, given bike has been laid up for a year. It may be that all injectors need to be cleaned

It won't be the CPS if the others are firing.

As Barmy says the injector is a good place to look. You could swap it onto another cylinder to see if the fault follows it, unlike modern stuff they aren't coded in.
