Benny,
Seeing 10psi on a fully warmed engine at idle is not by itself a reason to worry. However if you continue to see a decline (ie. next week it reads 5psi)that would indicate a potential issue. As the other posters correctly point out worn gears, oil viscocity, temperature (ambient and oil)are variables that play into the equation. Check with any HD rider and they will tell you low psi at idle is a way of life. A loping idle turns all accessories slower. I suggest not seeing a consistent low and high reading is the point of worry. BTW thanks (sorry) for this prime example of the beauty of this gadget being in your face. You can call me if you would like to discuss this further.
thanks
tod
