Swapping out stock gauges - RESOLVED w/ pics

Well then in that case I could always just splice into the extra wiring. That's good news.

My other question then, is, can I manually adjust the odometer on these things? I'd like the odometer to match exactly.

Thanks,
Jonathan

Are there scoots that actually come with a tach? Where would you get an instrument package that has one?

I do have to admit, I was confused by the tach threads until I realized they were electronic; all of my old bikes had mechanical tachs.

standard US speedometers were 1000 rpm = 60 mph. It was common for a metric one to read 100 km/hr at 1000 rpm. If your Chinometer is like that , you could run your speedometer up to maximum speed (80 mph?) and put on 1900 miles in a day. That could exceed the remaining life of a drill, so might get expensive.

Other input rpm/speed ratios have been used so YMMV

I´m not going to waste time fidling with the odometer unless it´s something I can just manually take apart and adjust it. I´ll see when it gets here.

I plan on fooling around with the old one. Thanks for the input.

You may have to hard wire since your scoot probably doesn't have the proper wiring harness. The green wire goes to ground (a good metal contact on the frame), the black wire goes to any wire which supplies power to the instrument lights, the yellow/black wire should connect to the wire which is connected between the coil and the CDI (usually black/yellow).

That last bit of advice was a God send. Green wire was grounded to the dash stay bracket. Black was tapped into the rear brake wire power line. The yellow/black wire was extended and hard wired into the yellow/blue wired that you can find at the top of the coil wires before they hide beneath the wiring harness. You´ll see two wires. One is red/black, the other Yellow/blue. Just tap in and you´re done.

Check out the photos.


This first photo shows the wires that control the tach.


This was what I used for a ground. I had to extend the ground wire about a finger´s length. Also, GREEN is the ground wire. You see black because that´s the color I chose for my extension.


This is the wire that you use to get the necessary info into the tach itself.

That´s that. Now go add one to your scoot.

OK, reviving an old thread here. I have the same dash as Johnathon. My tach wires are black, green and yellow/black as well grounded the green, power to the black, my coil only has two wires off of it. When I touch my extension off of the yellow/black to the wires off of the CDI to test, all but two (the two solid Black ones) kill the bike when I touch them together. Could I need to switch the yellow and black? ie: power to the yellow and black to the CDI? This really should not be to hard, proly something I am doing wrong. Thanks for the help as allways.
