I had a problem like that. it was the head temp sender. the bike would run only in neutral. when I put it in gear it would run on one cycinder. I cut the wire striped it and grounded the wire under a washer to get me home . then I put a hi4 ign. on it so I would not have to deal with it anymore. that could be it.
