It is definitely related to oil as I notice that after topping up the oil it misfires a lot more than when the oil is lower.
Cant get a photo of the spark plug atm, but come next weekend I should have time to post one.
Carb is completely clean and have done a few 100km. Apart from running slightly better at idle, it runs about the same as before. All jets are in good condition, as for everything in the carbs really.
Tried leaning and enriching the mixtures via the screw and both jets in the main and secondary carb and never really changed much apart from power. I have set it back to how it was originally being at centre on both jets and 2 turns on the mixture screw where it seems to have most power at least.
I kind of want to remove the head, cleaning up the valves and check the condition of the bore and piston rings etc.. but im worried about the inevitable problem of stripped threads... Its clearly not the original head on the bike as it has 2KF stamped into it and the frame is 4PT.
