Ive been reading this thread in desperation! My Yamaha xvs1300 has been doing this for over a year. It’s driven me insane! I’ve also done everything that’s been mentioned in these posts, but nothing has solved it. Though, you say bad ignition coil? It’s the one thing I have not replaced yet!! I just happened to have 2 new ones at home so tonight I’m going to go and put them on!! Thanks to everyone for the advice on this thread, I’m hoping to god this solves the dilemma is pretty much given up and was about to sell the bike!
let us know what the outcome is please
