Well how wrong can you be!!
Just been out on it, was fine for about 5 minutes as soon as it warmed up.. misfire, it was getting worse the hotter the bike got.. I am now thinking its NOT fuel related but electrical.
On tickover the rev meter glitches as if the power has been cut to it, the motor drops a few revs then picks back up.. does that 3 or 4 times then stalls.
Im going to try and borrow 2 coils to try, while Im waiting for those to arrive I am going to check the pick up for the ignition... who knows it might have moved.
Keep the ideas coming.. Im still lost on this!!
Might even try and get a diagnostics lead so I can hook the bike up to my laptop and see if any errors are there..
