View Full Version : How loud is your ride.
Here are the state of Ca. reg's for noise control that went into effect just before the start of this dune season. I'm told that virtually all stock exhaust systems have been tested and do meet these requirements.
Additionaly at a recent ASA meeting it was suggested that BLM feild managers will have db meters and rpm guages to test your OHV/ATV's.
I've sent a message to BLM El Centro office to find out if there are any "amnesty" days scheduled. (an anmesty day is a day were you can go out and ride with the intention of having your OHV tested by the folks at BLM without penalty). I'll keep you all posted of there response.
The below link will take you to Ca. OHV laws for noise regulation.

The below link will take you to a page that show some test data of OHV's with diffrent exhaust systems.

that is just stupid, worried about noise pollution in the middle of the sand desert.....
I know mine at idle is 112 Db and will rev to close to 126-128 Db... So I guess mine wont be complying with the new rules.....
I have no limitations, only my quad has limitations......

So, if I am reading the chart right, my 400EX with a White Bros on it is too loud. What a joke. I unloaded my stock pipes already, so there's no turning back. My next question.....how do I make it not so loud?

You put the stock pipe back on that you don't have.
Almost all the aftermarket pipes are above the limit, just a few that aren't.

I thought there was some form of silencer packing that you could use to reduce the sound.

Shannon, great question!
Right now I've got a message into the folks at BLM to see if/when they are planning an amnest day. I'm hope-ing to get mine tested by BLM when I go out there next trip. This will at least verify for sure if you are over or under the db rating. It will also verufy accuracy of previously posted chart I'll start diggin a little deeper to see what I can find out about maybe repacking pipes. (if it will be effective)

that is retarded, i know that any good exhaust will be louder than that limit. They yfz450 sparks pipe is like 106db or something like that, and if i get ticketed there for having my bike too loud i'm sorry to say i won't be going to the dunes anymore.

After reading the test proceedures, it sounds as if there is a +/- accuracy in the field of 3-5 db's maybe we are closer than we all think.

Cuts noise in half? Might not be ideal for sport bikes, but I have seen them on the utility quads. Do not know if they work or not, but says no loss of power. Add an exhaust system to get power and then something like this to reduce noise to be legal. Just an idea.

Well this is a sticky subject. However they will have to test in compliance with a Known procedure and if this is not conducted properly it won't hold up in court if you fight it. However Are you willing to take the time to drive to Ca to fight it?

Zhvonte, jet turbine engines make 120dB. I think you're in better shape than you think.

I am running a CT exhaust with race tip and its rated at 110 with stock engine, and mine isnt so stock, so unless the db meter we have is way off on the calibration, then I think its fairly accurate.... I do hope its way off, but after revving it twice, my ear rang for about four hours....

Bummer for you and anyone riding with (or near) you. Prolonged exposure to that type of noise will cause permanent hearing loss. Every 6 dB is twice/half as loud.
The upside is that you won't have any trouble hearing your engine on the starting line at PMP this weekend.
My CT Sonic (with 12 discs) probably only puts out somewhere in the low to mid 90's.

I've got a Radio Shack Digital Sound Level Meter. It isn't ANSI approved, but it should give a pretty good idea of the sound level of your quad/mc. I'll bring it with me to the PMP GP for anyone that wants to do a reading on their scooter.

How do they plan to monitor/enforce this? Are they going to pull everyone they see over and ask to sound test them? If you get sound tested once...and pass...do they give you some kind of sticker or something saying you passed? I can't even begin to imagine how they'll really enforce it. If they do, however, it will cost the duning world MILLIONS of dollars to get all of the bikes/quads back to stock and in compliance with the noise levels. I know I've got THREE bikes that will be over the limit according to the test results published. Even the so called "quiet core" pipes by FMF and Big Gun are over the limit!!

Thats just stupid. How are the sand rails supposed to be quiet. Our rail w/ a baffel ideling is louder than a piped 400ex!

Nick...as I understand it...rails/jeeps/sand cars/etc. are exempt. It is only quads, three wheelers, and motorcycles that have to comply. I've got to believe (or at least HOPE) that the dunes are exempt somehow from these new noise regs. They supposedly went into affect on Jan 1, 2003...but I never heard of anyone being tested or even informed about it earlier this year at the dunes. I was down there 4 or 5 times in early 2003 and never heard ANYTHING about this.

Ya, but still out in the middle of the desert isn't going to harm anything. I think these people (BLM...) are looking at to many details that dont really matter and need to look at the whole picture, which is be able to control the crowds w/o taking everything away from us and charging us for every little thing. I do agree that some things are being affective, but 10 yrs ago it was nice being able to pull up and park w/o having to pay for a weekend of fun and not worrying if your equipment meets standards or is quiet enough.
Ok ill stop rambling i just wanted to speak my side

I do not mind paying usage fee's when things are being done to make the area or conditions better. It is nice having the pit toilets rather you use them or not --- The old days of everyone just going for a "business" ride really was not a good deal. I also know that having the rangers & LEO's cost's money and unfortunatly is very necessary any more. I feel the sound requirments are completly rediculous --- I would rather the rangers stick around past sundown to control the dip sticks that seem to come out after dark than having to worry if my ride is over a 92 db sound limit..... In fact the sound of the quads & bikes is what I personally key in on when duning to know if someone is just over in the next bowl....
OK - I have ranted enough..... I love sand duning and have been duning for 23 years - Have seen lot's of changes, most for the better, some for the worse --- Envioro weenies can kiss my &@!
OK - that's my last rant...;)

Mr. Walker,
We will be offering free sound testing at Cahuilla Ranger Station on Gecko
Road all season. We also will have a green sticker amnesty day on Nov. 22.
You can come to the Ranger Station between 9am and 2 pm and register a new
vehicle. A copy of the rules and regs and more info are available on our
web site listed below my name.

This may be our wiggle room:
Enforcement Testing—When used for enforcement, this procedure is intended to be a pass-fail test. A ±1.5 dB variation due to changes in test conditions, motorcycles, and instruments can occur. Test to test variations within this limit shall be considered acceptable. If limits are to be set according to this procedure, these variations should be considered when limits are chosen.
Does this mean we can be be up to 97.5 db or does the 96 db already take this into consideration??

Do i understand this last point in the calif noise law to mean, arizona vehicles would be exempt ?
Has anyone been down to the dunes in the last couple of weeks?? If so, have you been stopped or checked in any way on the noise regulations?? I'm doing everything possible to make sure that I comply with all of the rules (registrations on quads, ATV Safety Certs, etc.) so that we don't have any problems. The one thing I'm not sure about is the noise regulations. I've got three quads with aftermarket pipes on them and I have no idea if they meet the standards or not. I guess on this one I'll just have to go...and hope that they DO meet the specs if tested. I DO know that my bikes are quite mild and quiet compared to A LOT of others I see down there.

Or you can just change you bikes registration to read 1941 and fit in to what should be #8 ;)
I had heard in the past, and I dont even remember from who, that it does not apply to out of state vehicles. That would probably depend on how long you were there before they decided if you were "residing" or not![}:)]
I am going the weekend of the 8th and 9th and doubt my "quiet core" T4 would pass the noise limit. It is far from quiet. I will post after if I do get checked or messed with. And my ride is street legal here.

Mr. Walker,
Thank-you for your inquire regarding out-of-state registered OHV's.
Yes, every OHV must comply with all OHV regulations effective July 15, 2003. Officers are issuing citations for violations of California's OHV noise regulations and red stickers riding seasons.
Help protect your sport by complying with all OHV regulations. For more information, visit the California State Park Off Highway Motor Vehicle Recreation Division web site at www.ohv.parks.ca.gov or call 916-324-4442 and ask for an information packet.

We just got back from the dunes (camped at Ogilby). The rangers came by and checked use permits...but did not say or ask anything about either noise regulations or Safety Certificates. I almost WANTED him to ask about the Safety Certificates since we went to the class last weekend and were all prepared!!
