The last two days I have gone for a ride my VN750 it has began to act up once the engine has been ran at highway speed for about 10 minutes. The engine cuts out just for a brief second repeatedly over and over and backfires a lot. It really makes the bike jerk a lot and the tach needle jumps from 4-5K real erratic. I noticed tonight that when it starts happening if I turn on the turn signals it aggervates the problem. The turn signal indicator lamp also flashes real erratic rather than flashing smoothly. It almost seems as if there is an electrical short that is causing the problem. Also, after an episode of this when I get the bike home and park it for a few minutes the oil and neutal lights don't come on when I turn the key to on. The first time this happened I thought maybe a fuse had blown so I checked all the fuses and none were bad. I let the bike set for about an hour and then tried the key again and everything was fine. Anybody have any ideas on this one?
