Noise Emissions

[YSS]

I always had my    classic MX  sidecars and the Metisse  logbooked  with MA. (after Port Pirie Titles)
I did believe that it would cover roadracing and VMX , because many people at the time did use their bike for  both disciplines.
I tell you , it is a lot better feeling ,driving to race  meet across to anywhere and you know, not even Peter Lawson and his crew can fabricate a protest from nothing and stop you from beating him in a race. .

I found this noise emission graph in the back of the General Competition Rules for 1979.
You'll notice the DB limits for the various disciplines were all equal on 110 DB(A); with the exception of the "violinists of the dirt bike world" (borrowed quotation), Trials bikes.
I would assume the trials bikes are way under the radar without trying, such is the nature of their motors and plodding style.

Do they still include these graphs in GCRs; I haven't looked at a copy since '79?
Anyways, that's how it was back in the day...

I had down loaded the Gcr's today,
Did not look for the graph but they have a table  in the section  12.10 on noise levels that gives rev's /length of stroke ,same as graph   to be used for measuring ,
also noticed that modern road racing is also allowed 102Db and speedway 98Db

As Ross stated earlier...We need to keep lobbying MA with emails and letters re: lowering the sound emission levels for Classic Motocross. It's no good waffling on all over the forum if you haven't made your feelings clear to MA. If we don't change this ruling a lot of vintage racers will be unable to race their bikes. It's that simple. Email your protests to Ross Martin [email protected]

Thanks to those of you who posted your protest letters on this thread.
I was a little unsure of my wording and they helped as a draft.
I've just sent this to Ross at [email protected] and I encourage everyone else to send your letters ASAP.
96db is unfair but right now it's the Law.
I've posted mine here in the hope it helps someone else draft a letter.
It's a tad wordy - but I had something to say.

Ross,

I’m writing to you as I understand you’re part of the group who can make a difference with regard to the current noise emission debate.
The purpose of my letter is to say I’m disappointed, and more than a little alarmed, at the current noise emission levels expected of the Vintage Motocross machines.
As you’re no doubt aware, these machines were built decades ago as pure race bikes.
Noise was not a consideration; and these machines are not designed to be muffled beyond a reasonable range.

The current expectation of 96 db seems highly unfair considering the Historic Road Racing machines are allowed a more achievable 102 db limit.
Both disciplines use machines from the same factories of the same era; and the same Marques fill the starting grids on respective race days.
As an exercise, I asked a young child to point out the difference in a photo of a Classic Road Race Bike and a Vintage Motocross Bike:
I smiled when he said, “One has lumpy tyres and one has smooth tyres...”; he’s not far wrong is he?

Let’s face it, given the similarities between the disciplines there can be no justification to single out the VMX bikes for a lower and quite unreasonable emission level.
Our Country and others are responding to ‘green’ concerns and this debate can easily be linked to this mind set.
The VMX community is no different in that regard; we’re not digging our heels in and refusing to budge.
What we are asking for is an achievable decibel level; parity with our Road Racing aficionados on “smooth tyres” at 102 db.

The VMX community as a whole is concerned over this issue and rightly so.
Our passion for the sport and the huge commitment in time and money is no less than that of the Historic Road Racers.
Given your position in the sport we ask you consider this request and put forward our group concerns to those who can alter this unfair limit.

Thanks for your time; I’d appreciate a response to my letter.

Regards,


Graham Newton

Well written Graeme.

Well gents I've found the universal panacea for the emmissions/whinger/NIMBY problem unfortunately it won't be to easy to put into practice we just need snow and lots of it.Keeps all the whingers inside and when they do go outside they will have fluffy ear muffs on.

I forwarded my opinions on the noise issue to ross martin and he had the courtesy to reply and mentioned that it would be forwarded to the MA board.

We just need a couple of hundred additional messages to add to the ones already sent.

Don't just whinge about it,send off your thoughts.

As the wise man said "put up or shut up !!! "

I was at Barrabool yesterday and they had a big-wig, high-tech sound man there taking readings from all areas of the track. We did four mock starts with full grids so it will be interesting to see what the feed-back will be. (after he de-cokes 10kg of Barrabool main straight from his sound equipment...)

Apart from personal letters,
this is the official form in the 2008 Moms for addressing rule changes /amendments. page 38

[Doc]

hypothetically speaking..if I were to race my bikes in modern events such as at North Brisbane dirt track or Coff's dirt track then hypothetically speaking which rule would apply??

same bike
same rider
same MA
but 2 sets of rules..

it makes something so very simple so very confusing....

Hmmm... it would seem that MA has made their rules at least partially based on how likely the tracks will be to annoy non-enthusiasts: Road racing circuits are usually built well away from houses, speedway and MX tracks less so...

At which point, the argument 'but we've got old bikes' probably won't be enough by itself. I'd dare say that we need to talk about sound energy (typically 2-stroke old bikes vs typically 4-stroke moderns), field sizes, etc.

Hi Guys,
I can tell you that noise regulations in NSW is102db as it says in the GCRs State legislation over rules the GCRs and in NSW the Legislation is 102db at 30 meteres from the racing. This came from your governing body MNSW perhaps we should be finding out what our state legislation is. Down here in Tassie I cant get a answer from anyone but I am looking into it. rule 12.10.1.2 page 91 of the 2008 GCRs

Cheers
Fatboy

It says" States overrule the GCRs." I think not,... otherwise my current Stewards update training I had 2 months ago ,and all the other instruction has been incorrect. Consult the 2008 Manual of Motorcycle Sport Page 41 section 1.4.0.2 and 1.4.0.3 ,1.4.0.4.  Basically it says an SCB (State Controlling Body) may make bylaws but only if they are consistent with the rules as in this book. note 1.4.0.1. The board may amend or revoke any bylaw made under these rules.
That is known in places as a "God rule"  meaning these rules in this manual "can and do" over rule any SCB bylaw or supp regs.
 It is wordy I know but please consult your 2008 manual people. No good looking at ANY previous year manual as they are effectively fully repealed and fully replaced by the current edition.
Keep on with all the protests and submissions , it will be reviewed . yours Tim

WAKE UP CALL !!!!!!!!!!!!!!!!!!!!!!!!!!!!
Oh and I know it seems like other countries unlike Australia have a free and easy time, But thanks to some of those countries we now have this sue the crap out of everybody bull forking shit!,  Why Because I am not responsible in any way for my own actions , bloated insurance scam set up we have now in Australia. You try and have a meeting "with if a blokes got $20 in his pocket, a bike and a good attitude lets race and sort the other stuff out later set up." It is a dream, no it is fairyland madness! Basically somebody, racer ,spectator, child or maybe their stupid dog that should never be there anytime... will get hurt (for real on not!) or complain that noise ,the "environment is being poisoned or some shit and lawyers will take you and lots of other people to the cleaners . No money  No classic races No nothing left except wasted bikes stored in sheds.   

Now feel free to reread what I just wrote over and over then tell me "That would never happen"
