Wacky Tacky

OK, I've looked through the fourm search and the vulcan verses and I think I might know what the problem is but since my issue doesn't relate exactly I'd like some confirmation or comment on this...

Normally when I'm riding at 55 MPH the tach is rock solid at 3500 rpm. but today when I was riding at 55 MPH the tach was jumping around between 3200 and 4000 RPM. It doesn't do it below 3000 or above 4000. I can't hear the engine miss or surge at this speed and I don't feel an loss in power. From reading other posts on electrical I'm thinking that it might be the coil or ignitor but I'm a total novice on wrenchin on this bike so I'm looking for a little help.

BTW sorry Cindy I hit the wrong button and it posted before i finished the first post.

Yes, it's my mid-life crisis.

Make sure you frame grounds under the seat are clean and tight.

It happened to me last fall around the same rpm's. It didn't bother me enough at the time to start looking for the source since the engine was running fine. About three weeks later I was doing a nut and bolt check and found that the frame ground was a little loose. My tach has not acted up since then, yours may have the same problem or your tach could be crapping out.

It sounds like the problem is only with the tachometer, since you aren't suffering from a loss of power or surging. Could it be the tachometer cable that is malfunctioning?

Garage
if the wire were loose, the tac would drop down to zero, now I am thinking a faulty tac since there is no noticeable engine problems. Try disconnecting the tack, and go for a ride and see if you can feel or hear the engine acting up. The reason for unplugging the tac is to make make you concentrate on the bike and not the numbers.

if your bike surges, and stumbles I would look into fuel delivery problems and your pickup coils

you might have a lose connection on the pickup coil.
