Help-Misfire, stuck on Isle of Man

[chad]

Deffo change back hes as test. Fuel tank neck drain blocked, water in tank?

that did cross my mind , water in the tank caused the same issue with a friends 1150

Bike Still Misfiring.......

So finally got round to swapping the Hall Effect Sensor (HES) and thought I'd cracked it. HES held on by one bolt and that was loose. Found suitable replacements, re-tightened and tried again.

Still the same.

Swapped the HES for a spare.

Still the same.

I think it has to be plugged in to a diagnostic doo-da to give me a clue now....
