muff9588 Posted April 4, 2010 Share Posted April 4, 2010 My speedo is bouncing up and down fluctuating about 5-10 mph. I don't think I have an electrical issue, it's been doing it for sometime and my tach doesn't do it. Is there something loose or does something need replacing? Thank you.

Are you using a speedohealer? It sounds like the pulse signal is being affected by something - either crap wiring or something in the signal path.

I'll check to see if there is any chain lube or other build up in the way of the sensor. Quote Link to comment Share on other sites More sharing options...
Byrdman Posted April 5, 2010 Share Posted April 5, 2010 Loose battery cables? Believe it or not, it has been the cause of similiar problems in the past. Quote Link to comment Share on other sites More sharing options...
