OK next on the problems list Last night did about 15 miles 2up free flowing traffic, didn't go mad urban and A roads just a bimble out, nice all was well bike behaved. Today 2 up again sitting in clogged roads 20-30 mph stop start you know after around 10 miles bike got grumpy started running lumpy felt it happening so pulled into a petrol station and she cut out. refused to start again for about 20-30 minutes, but on the way home free moving traffic never missed a beat idle was a little erratic. What the hell is going on?
