    Digital Speedometer/Tachometer

    I'm looking to use a digital speedometer/tachometer on my 77 gs750B project. I've never done a mechanical to digital conversion, just wanted to see if there were any specs I need to know before picking out the new speedo/tach. Has anybody done this conversion before? Any advice? As always, thanks!

    Have you looked at the TrailTech Vapor? I put one on my Kawasaki and I loved it. LOVED IT. TrailTech is an awesome company as well. They really take care of their customers.

      Thanks for the input. I haven't really picked out any particular model quite yet because I'm not sure if I'm looking for specific specs or the like.
      I've like the look of this acewell gauge:


      Or this one:
      Motorcycle, Racing, shop, online shopping, store, Exhaust, Billet, Chopper, Harley, Suzuki, Carbon Fiber, Titanium, Rearset, Suzuki, Kawasaki, Yamaha, Honda, Bike, Muffler, Full System


      I would ideally like on that also has all the indicator lights as well.

      Was Kawasaki already wired for a digital device or did you have get a mechanical to digital converter?

        I went with the base model Acewell on my 450, has indicator, high beam, neutral, and oil pressure lights as well as tacho and speedo, dual trip meters, highest/average speed and RPM, etc.

        I found it pretty easy to adapt as well, and tacho input I was able to take off the negative side of one of my coils.

        I made the custom dash for it as well to include an LED charging indicator and the stock gear position indicator:
