Post by: Hammy on Sunday, 10 April 2022, 04:06 AM
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

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.
