Here is what I have sent in Email form, I have also sent a snail mail the same to MA post box. Feel free to use or modify if you want Tim. But use your own name!!!!!!!!! Thanks.

"A petition to MA and the VMX and Speedway Commissioners in urgency to review noise limits in regards to Vintage Motocross and Classic Speedway, Solos and Sidecars , The current regulations from 1/1/2008 do not take into account that these machines were not designed to meet  "in anyway" the 96db limits, and will lead to the loss therefore of classic machines ,competitors and the viewing public of these very warmly received branches of Historic racing."  Both have more than fair rights to Historic Road Racings  higher allowed noise limit of 102Db  ! as per Manual of Motorcycle sports??
Thank you  yours faithfully and with respect Tim Derrick

YOu missed the bit about dirt trackers :O) 

MIne basically said ALL pre 77 bikes regardless of disciplines should have an outside limit of 102 DB, although all competitors had volunterilyagreed to continually endevour to get them as low as possible on a continuous basis, the 102db would be the outer threrashold for all classics,  due to the nature of air cooling and competion design was not made available to safely and confidently meet TODAYs lower levels in 2008.  In that chroniogical historic period any thing less than 102 would comprimise saftey, reliabilty and such of those historic machines and they would be lost to active racing forever.

any way mine continued as much the same, but stated the lose of competitors to the class, loss of revenue to MA if a seperate outlaw Classic register was formed like NZ and so on.

So if you are only allowed to fit parts from that period and you are not allowed to use modified parts outside that era and the bikes have to be standard then if they were louder than 96 Dba in 1975 then how do you comply... me tinks soemone did'nt think this one out...

Dave and Mark are indeed working on this right at this moment. Not every detail of this proposal needs to pass your scrutiny Freaky.

Here's the email I sent Ross Martin at MA.
Ross, as a Classic Motocross and Dirt Track competitor I would like to voice my concern at the introduction of a 96db noise limit for 2008. I'm sure you're aware that these machines were designed and manufactured in a day when noise regulation wasn't a priority. Being air cooled and featuring exhaust systems never designed for the silencing needed to comply with such a limit, I feel that the historical integrity of the machinery being used to compete in Classic Motocross and Dirt Track will be severely compromised both mechanically and visually.

I believe that the 102 db that our Classic Road Racing brothers are allowed should be a blanket limit for all classic divisions, no matter the dicipline. It is irrational to expect one faction of the classic movement to have a 102db limit and a 96db limit for the other.

By introducing a 96db limit MA is certain to drive competitors away from motorcycling due to their machines not being able to comply with an unfair noise limit. I would have assumed that MA was in the business of attracting new riders and machinery to motorcycle racing but this current regulation proves that the opposite is in fact true.

NO your right there, but being informed might stop us getting in the way or cocking things up, even help us to help them in a more organised way rather than our usual half arsed approach 

PS. two thumbs up on your letter !  send them in fellas 

[Rossvickicampbell]

Gents - only slightly off track (which is unusual for me) - what happens if I endevour to quieten my 73 Honda Cr as much as I can - travel all the way to Tassie for the Nationals and they decide it is too loud?  Is it correct you get a warning first - bit difficult to get a bike checked as well I believe?

mmmmmmm!!!!

thats what we are all about here - making sure that you don't get pinged at the start line in Tas after the big trip. Most bikes should be OK at 102db your not going to get to 96 easily. Once the message gets to MA then its hoped that there will be an exemption for the event and the commission can then move to fix the book for 2009.

Freaky and all,

We are working on resolving the 96db issue at the moment. Don't believe that nothing is happening lads.

This will affect the guys on the MA and state commissioners just as much as anyone else. On the MA commission I reckon we have about 50 old bikes between us, let alone all the states. We are plugging away...

Cheers,
Mark.

This topic is slowing down on the site, and not many letters of objection have been received by MA.

Please lets keep the pressure on MA to revise this rule.

They were doing sound testing at the Coff's Nationals.
Did any one take notice of what the readings were?
Did anything their actually make the 96 limit?

[Rosco400]

The blokes doing the testing were sitting on the grass near track exit where bikes were idling back to scrutineering holding meter no where near bike exhaust, actually didnt see any testing as per gcrs but didnt really take a lot of notice either, dont know if anyone got pinged but from what I observed, very relaxed testing procedures

Hi Guys,
I had my bike tested at Coffs as per the GCRs and it failed badly at 114db as I came off the track they called me a side and did the test.
I did a noise test day for modern bikes last weekend at a club practice day. I tested 37 bikes on the day 17 passed at 96 db 8 were between 97 and 99db and the others 12 were between 99 and 109db
The best bike was a 07 KTM at 87.4 db and the worst by far were 2 identical 07 KX 85 at 109db.The KXs had brand new procircut pipes and mufflers Costing $1000.00 each hence the owner has contacted the shop were they were bought and they told him that was impossible as factory testing of the pipe was at 103db. I think these company's should not be allowed to sell these things if they don't comply.
I am testing these two bikes again this weekend to make sure there was no mistake and then he is sending them back.

Cheers
Fatboy
