How many Minnesotans out there?
I found this at http://www.dirtrider.com/features/141_0309_sound
The standard SAE J1287 test method is the 20 inch rule that the California Parks and Recreation officials use to measure offroad motorcycles.</SPAN>
The test requires that the meter be held in a position that is 45 degrees off the direction of the exhaust outlet, back and away. The meter sensor must be at 90 degrees to that, pointing to the back, and the meter must be 20 inches away from the tail pipe with a wind sock over the sensor. All these criteria are specified in the SAE Test Procedure, which is an ANSI internationally recognized test procedure, implemented in 1979. It's also outlined in depth in the Motorcycle Industry Council Book. These angles are crucial for several reasons. First, in the instance of the KTM, the silencer ends with a slight angle, aiming to the outside of the bike. If proper angles were not measured carefully, the exhaust on a KTM would be pointing more at the meter sensor than on the other bikes. Secondly, the 90 degree angle of the sensor is necessary to avoid "wind" pops from the air flow out the back of the bike. A seemingly small puff of air can send the reading into outer-space. Also, there must be no objects within 16 feet of the test bike, and the tester</SPAN>

Brian from Faribault here, about 50 miles south of Minneapolis.
I've been to Bauer's Pit a lot of times, but only with the truck. I'm hoping to head to Bauer's on the quad this year!
