yamaha multi function tach oil pressure problem

[harbor720]

I have a yamaha multi-function gauge tachometer at any RPM from 3000 thru 4100 the digital oil pressure jumps between the two midrange markings when the oil is hot. Anyone have any thoughts? This is a new F200.

Completely normal. Oil pressure is not static. It varies over time. Even at a constant RPM.
