I have like 5 of those dashes and components all in varying condition, if you need them lmk will ship for shipping cost

The AR tach is driven off of the oil pump which is driven by the crank, so it is a direct correlation of engine revolutions

What you’ll run into with the plug sensor style is that they are not accurate and are actually harder to view and utilize imo - much easier to see a big red needle in your peripheral than a digital readout

A tach with a highly visible and accurate needle will help you to maintain rpm range - you could fabricate it on the P6 which is more than likely what others have done. The bikes in the videos with tachs are either highly modified race motors or factory gp products which are hard to come by, even basic info can be lost in translation

Check out koso, they might have something that could work
