I am rebuilding my Z1b engine and this will take quite a while to complete due to the sad state of my finances at the minute

I bought a Z1000 engine earlier this year for spares and decided to try it out because it looked in fairly good condition internally. Today I put some petrol into my bodged up auxiliary tank and tried the first start. The engine fired up after a few presses of the button and mechanically wise sounds fairly good apart from the slight shim tapping.

Now the engine runs but misfires on one cylinder and it is hard to stop it from running too fast on tick over, it is getting slightly better each time I run the engine but the misfire remains.

Now my question.

Could this be an inlet rubber letting air in? Or is there something else that would give these two symptoms together.

It is the first time my Z1B has had a running engine since 1984 and is a major boost for my motivation to get on with the renovation

WELL DONE
to check if it is the carb rubbers when the engine is ticking over, spray wd40 onto the inlet rubbers if the reves increase they may have some splits in them, have you tryed changing the plug leads round to see if they are broke? or change the plugs around mark the one that is not working (it does help not that i would know .

Thanks John, I will have a try at that tomorrow, I will have to give the neighbours a rest for a while, the Harris exhaust is louder than I remembered
