Vapor

I have never had a speedometer or any other instruments on a moped before. I decided that should be changed for this build. I wanted to be able to see speed rpm and water temp. I was going to build a dash and mount the tiny tach and the gps speedo I have and then go out and get a water temp meter. I decided that this thing would be a much more elegant solution and the price was right.

nice. how accurately does that read rpms? I have plans of building a little dash for a speedo a nd tach. Whats the price look like?

It has a pick-up that wraps around the spark-plug wire that senses the pulses your coil puts out. People that run this type of setup with puch's have had some issues. When I had my TinyTach hooked up to my Rigid running CDI the meter jumped all over the place. Something to do with a lot of excess Radio Frequency interference (same reason wireless speed's never seem to work). People say that you can run R (resistor plugs) and that will fix the issue.

It cost $100, I picked it up off ebay. Here is the company who builds the things web-page http://trailtech.net/motorcycle_vapor_kits.html
You want the kit that has a temp sensor that fits a moped sparkplug (14mm?)

A temp sensor would be very comforting, if nothing else.
