GL 1500 SE speedometer
Well, my GL1500SE speed indicator is off just a bit like all of them. About 3 mph faster than actual ground GPS speed at 60 mph. So, while I have most of the fairing apart to do some other wiring work, I figure might as well dig into gauge cluster and see if I can do to this speedo like I did to my 81 VW Rabbit. Took cluster apart and then holding the drum the magnet on the end of the cable spins, I moved the needle back about 2 mph. By the way, there is NO fluid to leak out of the speedometer. I have NO idea how this got started many years ago. But, it had to be someone who has never been inside a automotive speedo or any one for that matter. Now just have to wait for the spring thaw, and the way our weather has been this winter, that will possibly be around May 30 or so. Then I will compare it to my GPS. That is all for tonight.
