I have been checking in with this board for a while now and finally registered so I could ask some questions.
I am eagerly awaiting my upcoming purchase of a WR426 and wanted to ask some questions of the Michigan members.
I will be joining the CCC in Michigan and would like to know whether or not the 426 will pass the 94 dB sound test with the "free" performance mods - baffle, airbox, stop and grey wire. I want to have the best performance I can but want to comply with regulations.

Too late...I've been having trouble falling asleep ever since I decided to sell my street bike and get a trail bike. By the way, anyone looking for a 94 Honda Magna, 750cc V-4, with tons of goodies? I'm in Michigan.

Our particular dual sport club measures the sound at idle 20" away from the tailpipe at a 90° angle. The sound level is considerably lower there than at 45°. It all depends on the criteria established by the sanctioning body or by the riding area's/State's requirements. It's my understanding that the local requirements in my area are to be less than 94 dBA at 35 mph, 50 feet away. Since that would be a difficult measurement to make, we substitute the idle measurement 20" from the pipe. This seems to satisfy everyone.
My 99 WR400 was the loudest of the entire group of over 100 different bikes (various makes and models) at idle with a measurement of 87 dBA. I have an FMF Megamax II muffler with a quiet core insert and 12 disks.
