I did a quick, seat of the pants reading on my bike out on the driveway.
At rider ear level I recorded 96 db at idle (1500 rpm); 105 db at 2500 rpm; and 107 db at 4000 rpm.
At a point 12-ft. behind the end of the pipes and two feet off the ground, those numbers are 93 db at idle, 101 db at 2500 and 109 db at 4000.
I have Bub Dresser Dogs, AI removed and 125 jets (I think).
May be interesting, but only if we have something to compare the numbers to. I want to do this again if others are interested, especially the off-the-bike readings. It was tough to do alone.
Let me know if any of you would like to use my sound meter.
BTW, I would recommend against leaving the meter on the seat when setting the throttle. Apparently the vibration causes the meter to slide a bit and fall to the ground. It's just a theory, but since it happened twice I'm either on to something or just dumb.
