Cutting out on me

OK, now I thought this may have been a fuel issue (posted other thread) but I now think it has to be electrical. The engine keeps cutting in and out when I'm riding and the tach is bouncing all over the place when it does. Does this sound like an ignition problem? It is NOT backfiring. Just not sure where to start ripping it apart. When I'm sitting in neutral, the neutral light seems to flicker when I give it gas and it won't hold a steady RPM (bounces all over) As of right now I just took a 2 mile run and barely made it back it. I'm pretty tired from working 3rd shift, so it will have to wait till later this evening or tomorrow. Hopefully I will have some suggestion by then.
Till then, Good night.

I had a similar problem with my tach bouncing and it was a bad connection at the battery....

All I have to say is WOW, the negative battery teminal was very loose. Tightened her up and she's running like a top again. I don't know if that's the first place I would have looked, but I'm grateful for the solution. Thanks dariv, I guess that's another thing to put on the list for things to check while doing maintenance. I really thought this problem would be a real head scratcher, but that fix was a simple as it gets, and I only needed one tool to do it, the nutdriver that I have in my tool bag to remove the seat bolts is the same size as the nuts on the battery terminals. Someone was really thinking there!

Same thing happened to me; loose negative battery terminal. I found that the battery was not being held down firmly and shifted a inch from side to side. Over time it works the battery terminals loose. I added a shim under the battery hold down bracket and added lock washers to the battery screws to solve the problem.

when he said the neutral light was flashing (and my tach would sometimes do weird $hit) that threw up a red flag for me . mine would sometimes be a pita to start . i took the seat off and sure enough the negative cable was very loose on the battery, i could see where it was arching . I tighten her down and the bike cranks over way faster wow this fourm amazes me
