i would fair enough for mx and endruros for not having wheel spacers and for being a pig to turn.but im talking about racing around a flat surface for 63 seconds wider is better for speedways safety.bullet and i have spoken and hey still a bit bummed but thats life.danny the bike was brought from bullet yes but it has that many changes to it that it goes faster with a finely tuned athelete like myself on.bullet used to have it narrow i have it at 1370mm wide and it rides like a dream

my can am never reached over 49.5 inches as i only ran lonestar a-arms which are +1.75 each side and with the standard offset rims on a 46 inch standard quad.
don't know what can am your looking at but i was sponsored by ITP whilst riding my Can Am.

as for my polaris its 1250 wide, it goes a little wider when you put 11 inch wide tyres on the rear but depends on the brand. all these things would have to be considered if you want to meet the rules.

50 inch is very cost effective and being wider on a speedway track is a big disadvantage if your behind, if you are always out front like you yeah mate na then i can see why you want to keep the 1500 wide. but then again you can make your quad 2m wide if your smart enough on the track.

this rule will most likely pass for MX and XC and maybe speedway if not this year the next as its pretty standard issue i think.

Question for those who do there best to kill the 2 strokes,

A standard Banshee is 346cc,
The rules say a banshee is 350cc,
Standard head displacement is 22cc per cylinder.

Does that mean I can bore out my Banshee to 364cc,
which is 60 thou over or 65.5mm per cylinder,
then fit a head with replaceable compression domes with a displacement of 15cc per dome which would bring the total engine capacity to 350cc, which is what MA state in there rule book that i should be running?

thats what you call check mate sounds like you bent the rules just right!!!

[Clarkie]

Not bending the rules, just my interpritation of 350cc, 450cc 4 strokes have different bore x stroke x head cc configurations to get 450cc.

And it allows for 5 rebores which i would rather do at $40 per cylinder than $845.00 per cylinder. ( genuine yamaha)

I agree with you I feel that is legal cos if you cc the cylinder it will be spot on. Did you get on to Daniel at South East Marine.

so you are telling me that its fair that i bought my banshee with alreay oversize pistons and just to race i have to get them resleaved so its 'legal'? it cant be the same cost as a four stroke for resleves, remember there is 2 of them! if they are able to be bored out why not alow it? too many people will be in the sport and it will be harder to govern? dont like that sweet 2 smoke smell? Thats all it seems to me. The power difference is SFA between the std and rebore and the 4 pokes you can do oversize valves cams high comp pistons and the banshee you can have stock bore and i bit of a port? is that it? All these 2 stroke rules are just going to have less 2 strokes compeating or more people lying about their machine.

I am not completely sure but if you run 15cc domes your motor will not run on 98 RON fuel it would have to be 110 RON , I don't think 100 RON would be enough either and thats the max we can use .

I was wrong LOL, the engine is measured in swept volume and the head capacity has nothing to do with it. Worth a try anyway.
Remember guys im an Autoelec not a motor mechanic

As far as I know 19cc domes are the lowest you can go on pump fuel anyway without mass detonation

My point also!

How does MA check the capacity of an engine at the moment without ripping the head of the engine? Do they bubble test as they do in Car speedway?

whats a bubble test ? any footage around of that being done?, I think you have to pull the head off to be 100% accurate.

Mrs Gatior i applaude you for saying what most of us junior parents are thinking and also sending into MA I agree on a rec class that is NON COMPETITIVE MY 2cents again

why would people who claim to be "all for the juniors" want to stop any kid from having a class that they can be competitive in??

fast riders on fast quads should race each other, and there should be classes for the not so gifted and/or fortunate too. isnt it all about growing the sport?? i realise that numbers are required ,b ut hey if there are numbers then let everyone race.

we ran a class with awards a couple of years ago for seniors who didnt want to have the most expensive equipment,and/or ride the length of time the pro's do. it was called quad lites. we should try to accomodate as many comfort/ability levels as possible if we are to grow the sport. there is potential for the best future rider in the country to emerge from the shyest and seemingly most timid 7-9 or 9-13 year old. remember, sometimes kid's aren't given their first taste at our sport until mum and dad are comfortable with them doing it or perhaps can afford it, and that might not be till their kid is in their early teens.

Spoke to an engine builder today, can only be done on 4 strokes, basicly they fill one chamber through the plug hole when its BDC with a special liquid then hook up a special measuring tool, wind it back up to TDC and it records the SWEPT VOLUME OF THE CYLINDER, then the multipy it by the # of Cylinders. they naturally remove the rest of the fluid before starting the engine. they say its within 2cc per cylinder accuracy, if theres a challenge then its pull down time!

In the MoMS there is no actual stated method for measuring capacity but they do state a formula that must be applied. IMO this means the bubble method would not be allowed as it does not give measurements it gives an end result of X cc's.......BUT is seems up to the disscresion of the clerk of the course. The measurement shall be performed at the end of the meeting.

It's worth noting that the expense for the measurement is down to the person in the wrong......if you protest and are wrong then you are up for coolant, gaskets & whatever "labour" that may have to be applied.

And thats one of the problems.... Here in SA we dont have one.
And the Quad Advisory Committee's answer to that.... Make more rules that can not be challenged.
Shouldnt we Police the ones we have now before making new ones that will never be checked?

just been informed the the proposed rule changes are going to be heard at MA head office ON 15/2/2011, those that have previously had some thing to say on this matter should re send there concerns ,to your local Bord member or direct to CEO, MR DAVID WHITE.

CEO@MA.ORG.AU

[bullet]

You only bring up 2 points and they are both wrong.
The Board of MA are meeting on Wednesday the 16th...
and anyones contact would be their NQAC State Delegate or MA's Communications Manager, Ross Martin ross@ma.org.au

I guess you sent out your rubbish message to a mass address book of some 50 people just to cause trouble?
"ITS ON AGAIN please re submit if you feel the need this is being brought up again with out any notifacation to members see OZ atv"
Some of the people you have e-mailed are also making contact to state that they disagree with you or to just complain about your conduct.

If YOU need to Danny, contact MA yourself and ask your questions. Try working with 'some' correct information.

yes bullet well said i got the date wrong better a day early than a day late hey
as to cause trouble , for who have i cause trouble ? you? the NQAC ?
sorry to those that i might of offended just bin the old mail , spam it called i believe but if i got threw to a couple of people that it does concern great !

too many people have been misinformed and as my post said this is from last year .

Like it or not people don't like changes thing need to move slowly and with alot of consultation to see whom it will effect of cause not every body is going to like changes but keep every one in the loop

I have tried to find the minute from the NQAC meeting on line and at the club not been able to get a copy. have now and they are still from June 26&27 2010 so what changes have been put forward ? i will read threw it cheers

too many things are trying to be change and mistakes are being made eg; people led to believe there 7-12 y/o kids can race 125 four strokes quad ,you know that it has already happened

iam all for changes fair and just racing
club to nite !!!

[bullet]

Wrong again Danny.
Who knows what you are telling people.
Even the NQAC recommendations from back in June (1st draft to consultation) recommended that a Junior 9 to Under 13 year old could ride a 125cc 4 stroke. And this is still the current recommendation.
No-one has ever said a "7 - 12 y/o kids can race 125 four strokes quad".
So that is not a very good example of an NQAC mistake.

Just YOUR publically promoted mistake again.

The NQAC is very mindful of the chance of making the odd mistake in going forward, but this will not deter our aim to ensure the best for everyone in Australian Quad Sport.
Among other factors, we need to be very front foot to adapt with advancing technology in our industry.
The NQAC undertook the broadest member consultation last year, and we look to further improve on that for 2011 and into the future.
