Eligilibty scrutineer at the Nationals

[Nathan S]

Oh, and an eligibitly question:

I have a set of 35mm "Betors" from a Cooper. Are they legal for pre-70?

[albrid-3]

Betor Front fork are ok, bultaco, ossa. etc. Betor have been around for a long time.

[GMC]

Why do rules turn some of you guys into such drama queens
Pre 75 simply means a bike built Pre 75 or from Pre75 parts.
The rules are flexible enough to allow any exhaust, tyres, handlebars or ignitions.
You can port away to your hearts content & use any size carby you wish.
You can use almost any rear shock & internal fork mods.
You just can't use later model parts or over bore outside of the class your running in.

If thats all too hard then build whatever you want & run it at the Classic Dirt events where you are sure to have a ball, but don't be talking the rules up to be so anal because it is only guys that step outside the known boundries that come to grief.

[Oggy Doggy]

I couldn't agree more GMC. All of the stuff mentioned here like the suspect 125SL, that bullshit "riveted CZ hub" thing that's been blown out of all proportion, Crammys TM125 and even the Vern Grayson saga happened 14 years ago ago and since then it's been boringly plain sailing with few dramas. I've been following this thread for years (trust me, it's been going on in one form or another for years) and some guys seem to want to turn simple, easy to follow rules into the Magna Carta. Just build the bike to the simple formula that GMC states "Pre 75 simply means a bike built Pre 75 or from Pre75 parts.
The rules are flexible enough to allow any exhaust, tyres, handlebars or ignitions.
You can port away to your hearts content & use any size carby you wish.
You can use almost any rear shock & internal fork mods.
You just can't use later model parts or over bore outside of the class your running in.
" and you won't have any dramas.
Worrying over how many ribs are on a Yamaha hub is anorak pedantics at best. Use the pre'75 hub (or whatever part is giving you heartburn) and forget everything else. I've been building a long term project  DT1 pre '70 bike, don't even own a rulebook and bet it ends up 100% correct because I've kept everything within the era and haven't gone looking for loopholes.

[albrid-3]

Totally with you GMC, AND OOGGY DOGGY, what l raced  at nationals that year ( Maico / Honda  125) is dead and berried, l won on the day because l rang the neck out of it, and paid the price by surrendering my win. All l can say now that you fellows get on with it and build your bike to the period. its all in the GCR. end of story.

[Nathan S]

You know, I agree. But:

I am stressing a bit over the Yamaha front hub thing because it means quite a lot of extra work for me, if I need to change it for the Nats.
Previously I'd been comfortable in the belief that the later part was acceptable as it is within the spirit of the era, and clearly offers no performance advantage.
Now we've got a VMX Commissioner and eligibility scrutineer telling me that its not what the rules say, so its not acceptable.

And that's the crux of the matter: Whether we like it or not, there ARE grey areas, and people are going to see the shades of grey differently to each other.

So I want the air cleared before I load up the ute and drive 16 hours - I sure as hell am not interested in driving that far to be told to go home...

[GMC]

I agree Nathan, there are some grey area’s that need addressing, & their probably always will be. These threads are always good for bringing stuff out in the open for discussion. The scrutineers can’t be expected to know every detail for every model ever built.

It seems your Yammie front hub dilemma puts you in the same boat as the riveted / bolted hub scenario which as oggy says has been blown out of proportion
The rivets & bolts had nothing to do with the protest, just as the fins on your hub will mean very little either but they will be used as a means of describing the early & later hubs.
I believe it has now been decided that the later hubs are okay on the CZ’s so I would assume the same will happen with the Yammie hubs if someone puts it in writing to the commission.

In the meantime why don’t you just machine all the fins off your hub & if they are truly the same then know one will know which hub you have machined down.

While I have no say it what is allowed on the track I would assume with your situation you would be allowed to ride but may be up for some anal to protest if you win, which will actually make you more famous than the win itself.

  "Within the the spirit of the era " usually means I haven't read the rule book and I hope that they don't look too closely ,  or,I know its the wrong part but  I'm too lazy to put in the extra effort to find or fit the correct part.

[Tim754]

Benelli Sei, ran single pot Brembos in 73/74 got a sales pamphlet somewhere here.  Legit to me, on pre75 sidecars  is not any period "single pot" caliper Ok via the rules?
Ahhh yes my Ducati 750 (1974 model) ran Brembros!!!!

[shorelinemc]

should be legal if available prior to 31/12/1974

[shorelinemc]

no complants here about using a brembo caliper,the other Qlders won`t care either

[Graham]

anyone know if methanol is legal to use in the evo class

[VMX247]

anyone know if methanol is legal to use in the evo class

all I found was in the SX MX section 17.4.0.1
must be unleaded
no more than 100ron
contain no additives other than thoses added at the point of manufacture except for:
lubricating oil for 2 stroke engines
upper cylinder lubricant for 4 stroke be readily available from retail petrol pumps within  aussie or be a brand fuel homologated by MA that is compatible with fuel  Quality aussie standards act 2000

and for Road Racing
Methanol with exception of period 5 solos
or unleaded that is no more than 100 RON
no additives
Aussie Standards act 2000

12.9.3.1 the c of c,steward,scrutineer may direct the administration of fuel tests
looks like Classic has been left behind on the fuel item 
another idea we where discussing here at home the other day, is to make it easy for  new people to the sport.Print up each individual discipline books.Having that choice of buying/givin which one is needed. 
cheers Alison

18 Classic Motocross & Dirt Track

18.3.0.1 Methanol is permitted

[Graham]

Thanks guys I wasnt shaw so just got of the phone to MA in Melbourne and they confirmed EVO's are now part of the classic group as apposed to pre 85 and pre 90 which are not included , and as such can run methanol
