    80 750 tach and speedo probs.

    OK, I've read all the reports on the tach problems and even how to fix them but before I dig into mine I was just wondering if anyone has had any experience with my model and year in particular. Both my tach and speedo run slower than the actual speed. At approx 80kph my speedo is registering around 60. And the tach reads very slow and won't rise above 2500. At a fast idle it doesn't even register. My model has the big boxy square headlight and gauges. And I have already tried letting light oil sit in the cable mounting holes(with the gauges off the bike and upside down) but that didn't help.

    I would loosen the tach and speedometer cable by the gauge and lube them real good. A company call Champions Choice Inc. has a product called Cable Life and comes in an aerosol can. See www.protectall.com

    This is great stuff and should lube the cables real good so that they spin freely. The other thing to do is make sure that you don't get lubricant on the back of the gauges where the cable connects.
