So far this year, the only Dist37 Races we have been sound-tested have been the Enduros. I might need to figure out another way to warn slower racers I want to pass, ahead of me on the real tight stuff. I hope I hear the fast guys wanna to pass me, before I get knocked over. A couple Quick full throttle Revs will be harder to hear now. Oh Well, atleast I saved my stock Muffler.

The rangers were passing those cards out at the entrace to Oceano when I was there a month or two ago. Its still sitting on the floor of my truck. I like having noise continue to not be an issue for me. EDIT: but then again its not an issue for a 1997 Mx bike either

Here in Washington they have been sound checking bikes at almost all off-road events(not sure about MX) since last year. This year they say it will be enforced. Instead of by year they make the differance by wether the bike is air cooled or water cooled. I think it is 101db & 98db respectivly. I don't worry, I still have stock muff on. I go to sound check, the tester only looks at what the bike is, GIVES me sticker without testing & tells me to stop wasting his time.

This card says "Off Road Vehicles", does this mean that it does not apply to street legal dual sport bikes?

Yes, it does not apply to street-legal dual-sport bikes. They are even less, as follows:
27202. For the purposes of Section 27200, the following noise limits shall apply to any motorcycle, other than a motor-driven cycle, manufactured:
  1. After 1969, and before 1973 88 dbA
  2. After 1972, and before 1975 86 dbA
  3. After 1974, and before 1986 83 dbA
  4. After 1985 80 dbA
CA DMV Vehicle Codes: Division 12, Chapter 5, Article 2.5, Section 27202, Motorcycle Noise Limits

I'm just curious. How does it work if say you have a 650R dual sported.. will your bike be recognized as Off Road or as Street Legal?

When I was Tested by the US Forestry at the 2002 Bad Mountain Qualifier in the San Bernardino Mnts, one guy would look up the Year & Model of the Bike in a RPM Guideline Book, and then he placed a device on my Number Plate (that would regester the RPM by Vibration), and instruct me to throttle up or down, as another guy held the Sound Tester at the rear of the bike.

If this remains the same procedure, then I would think you'll be tested as an Off-Road Vehicle, since thats how your bike would be classified in thier book.

Probally wont be long until Dual-Sport conversions are outlawed like our FREEDOM has been torn apart, a little bit more with each EPA Law passed!

That's the same way they test 'em up here in WA. It was interesting to hear that CA has different criteria for the Dual Sports but I guess it makes sense. I was just curious to see if the plated "off road" bikes would run into some problems but it doesn't sound like it.

Anyone want to sell me their stock exhaust w/baffle? I never got one w/my bike (used.. yadda..) and my super trapp definately doesn't meat that standard (it's as loud as a stock YZ250F). Yea im dead if i go to foresthill. F^%$ING SH*#$ TREE HUGGERS NOISE POLUTION BS!!!! ok now that's over

My experience at Foresthill is the rangers want you to think that they will get their decibal reader out, but they are really there just to check spark arrestor.

I've been at Sugar Pine Staging area and the rangers are walking through the camping area and they checked the end of the pipes for sparkies, but they didn't ask anyone to fire their bikes up.

If they do come around just take most of the discs out of your supertrapp then replace them after they leave or once you have left the staging area. Three bolts right? Later, D
