Tach that calcs speed

[ironbutt]

I'm using a Predator 670cc on my old Honda motorcycle. It will have a battery and lights...to be used on the street.

I'd like to hook up a tach with a speedo conversion on it rather than use my cell phone app.

Is there a simple electronic tach, like the ones that wrap around the spark plug, that will convert to MPH too?

I'm using a centrifugal clutch so with just one gear I should be able to use a single conversion.

Thanks,

Get a illuminated spark Tester... Then count really fast... they sale these

Well there are GPS speedo's...
They don't need a lead to the spark or any other, than power.
These ones are relatively cheap.. And for mph..

I have a few of the speedhut gauges including a few canbus shift lights and 2 or their gps speedometers. They are really nice. But you gotta have a battery.

Also a huge note on trailtech stuff. The wiring is super thin so be careful stripping it. I had one on my kfx450 quad. I had zero issues on that brand also.

And for the record I am doing this on my new one. A koso branded one...........
