These tachs are electronic...they measure off of spark frequency...(#sparks/per), i.e., spark per minute is same as rev per minute (sparks once per revolution, right ?). Just like a car electronic does.
Do what Niterider said....makes sense...check all your bullet connectors...my tach went wacky once when one of my front turn signals wasnt grounding right. A lot of the VNs electrics are interconnected, so one issue will cause others, its just another dumbass Kawi design...add 50' of extra grounding wire, instead of grounding to the frame...just dumb...
