The problem you are describing is typical of an inconsistent ground connection. Most common location is the group ground connection located on the front frame extension.

My wife and I were on our way to a local event on Sunday morning when suddenly the tachometer needle started jumping, then settle in about 1200 RPM too high. It continued to occasionally jump, then either go back to normal, or back up to the same 1200 high a number of times as we drove. Around the same time, but NOT at exactly the same time, the voltmeter needle jumped a little bit. Unlike the tach it stayed at the correct level most of the time, then would suddenly swing wildly over a 6 or 7 volt range for a moment. [moderator snip]
