1977 GS550 Tachometer Drive Ratio?
Has anyone used an aftermarket mini-tach?? My 1977 GS550 is now a hard-tail bobber, and I would like to NOT eliminate the tach drive wire, and put a more compact tachometer instead of the old gauge cluster. Has anyone used or gotten a tach? Or does anyone know what the tach drive ratio is?? I found somewhere that maybe 5:1 but I'm not sure how reliable that source would be and I need to get a tach within a day or so. Any help would be appreciated!!

With the front wheel raised, count how many revolutions the cable makes when rotating the wheel one full turn. You will have your ratio. -
