Wasn't exactly heavy rain but I'd ridden on a bit of muddy woodland and then out onto the road during a bit of British drizzle. Suddenly whilst under power the mother of all mis-fires. 50% down on power and felt like the bike was going to stall if I backed off the throttle to idle.
Clearly something was getting damp, my concern was that it was something like the ECU and I didn't want to be stranded so nursed the bike home for 5 miles or so before stopping to check it over properly. First place I checked was the HT leads and sure enough the front lower (front facing) lead was sparking out to the cylinder head. I rotated the cap a little to move the lead (end of the elbow) further away from the metal of the cylinder head and it was sorted, bike back to normal.
In my experience, once something has started arcing out it will do so again so there may be a tiny crack or something. The bike has done 1000 miles. Anyone else had any problems like this and or recommend a decent set of HT leads? Years ago I remember changing HT leads when problems like this occurred on old cars. This is a 5 month old bike so I guess it's faulty. I've got the race map running with Termi so this will almost certainly up the HT voltage a bit as part of the map but still it shouldn't arc out.
