Hrmp. I don't know. My buddy has the same db meter that the warden does, and he has the calibration tuning forks too. Maybe his is not working properly. But I have to be quiet. The warden knows me and said he will ticket me next time. I keep moving the tracks farther out into the middle of the lake as soon as ice conditions allow me to, but the prick still comes out and checks all the quads. Needless to say my YZ125 will be as loud as possibil this winter.
