Sounds pretty normal to me. Also keep in mind most oil pressure gauge mechanicals are intended for car engines, there isn't enough volume in motorcycle specific gauges for economy of scale to offset higher production costs. These car gauges are intended to operate primarily in the 20-60 psi range and calibrated that way, so they can be wildly inaccurate in the single digit range where most bikes operate.
Yeah, that oil pressure gauge you bought for your bike may be much smaller than a car gauge, but the inner workings are the same, more often than not.
If your low numbers still worry you, go up in oil viscosity. That'll bump things up 2 or 3 psi for you. I run 10W-40 for most of the year but ramp up to 20W-50 for the summer. Just make sure to change back when the summer is over, unless you have a kick starter to stir things up before pressing the magic button.
Except for my gravedigger, she runs 20W-50 for three seasons and straight 50 for the summer. Old tech, don't ya know...
