We had similar sounding mis-fire on a long trip in France a couple of years ago...repeated fiddling with plug leads at the roadside stopped it for a short periods...on return home new leads have meant no recurrence...original leads looked/measured ok so no idea what was going on
The fuel pressure seems fine at 48PSI but of course I cannot check to see if it is dropping under full throttle load. I am suspicious that it might be plug leads or the coil pack. I will phone Marcassus in Toulouse to see if they have spares. Does anyone know if it is possible to fit a Harley Davidson coil pack? I have an H-D Dealer at Roquebrune sur Argens about 40 km away.
