EDIT: should hav put a linky http://www.motorcyclingnz.co.nz/down...web%20site.pdf

Also, please note that this is in the PROPOSED rules, it isn't official yet.
I am guessing you can choose which class you enter in, I guess it is kinda what Red was talking about, good ideas IMO =P

[Tony.OK]

Crickey...................only F2 though aye.

Wouldn't it be nice if MNZ would get into modern day and do mass emails for any announcements.

Well spotted

[Shaun P]

Its weird they dont appear to allow valving changes, the concept is good for an entry class though.

[johnsv650]

great idea, but why not say rear shock open ?
a 600 with standard shock tyres wont last 15 laps.......

[lostinflyz]

first sensible thing ive seen in a while. its basically superstock 600 rules.

most club/track day guys get a couple of meets outta a supercorsa on stock stuff. if your really burning up a tyre spend 2 grand and go supersport racing. i like it. theres the choice to be cheap or go hard out.

only thing i dont like is having to use stock brake lines but hey if you want braided go up.

[k14]

Thats wierd, you can add a power commander (by the looks) but not able to change the rear shock??

[Robert Taylor]

Indeed, springs are about position, DAMPING IS ABOUT CONTROLLING RATE OF CHANGE OF POSITION. These rule proposals show a lack of understanding on that count. For example if I was a 75kg rider on a GSXR600 or R6 Id be noticing straight away that theres an acceleartion squat issue off especially the tightest turns. An uninformed approach would say ''fit a firmer spring'' When in fact for the same $300 that the spring would cost you a few simple internal valving tricks would in fact yield a much better result. FACT. Plus the bike will ride bumps better because it wont be oversprung.
AND, how are they going to police it?

Obviously PP will be approaching you to act as Chief Technical Inspector (Suspension)......

The privateers thing looks to be more of a clubmans type thing running in the main race but still a good idea if encourages more entries i guess.

A true privateer class would be all running the same rules.

I will most certainly run in the main class but part of the rules intrigues me...

Firstly you can change the 'black box'

3-25 Ignition/Engine Control System.
Spark plugs may be replaced.
Igniter control modules may be replaced unit (Blackbox)

This would allow kit ignition.

But then the cheaper part of 'kitting' the bike, the wiring loom to go with kit ignition would seem to be not allowed?

3-16 Wiring Harness.
The standard main wiring harness(s) must remain intact. The only wiring that may
be removed from the motorcycle is the wiring between a component that may be
legally removed and its closest connector. Any electrical component removed must
be able to be reconnected to its original connecter and function normally.
A wiring jack/ harness may be fitted to accommodate an aftermarket fuel tuning
device.

As I'm happy to spend my cash or that of some sponsors in the main class seem strange to allow the kit ecu then ban the cheaper wiring loom to make it function correctly??

[Maido]

As I said in my first post (after edit) these are PROPOSED rules, not concrete rules,

It also says: Please put forward constructive comments with reasons on the following (submit to vicky@mnz.co.nz); your comments will then be forwarded to the Road Race Commissioner Paul Stewart


MNZ have a rule change proceedure which can be found on PDF here:

http://www.mnz.co.nz/download/Compet...nge_Policy.pdf


Read the proposed rules (there are some for speed attempts and superbike also), and put your constructive comments to the above address.
We know here on this forum FOR A FACT that we are all talk (face it, its true!) so instead of wasting your internet ink here, email your thoughts to MNZ! I have!

[Teambwr47]

Maido,

Missed the 'proposed' bit in your first post mate, I'll be sending my comments regarding the Sport Production 600 main class to MNZ.

[Teambwr47]

first sensible thing ive seen in a while. its basically superstock 600 rules.

most club/track day guys get a couple of meets outta a supercorsa on stock stuff. if your really burning up a tyre spend 2 grand and go supersport racing. i like it. theres the choice to be cheap or go hard out.

With respect the Superstock rules are generally accepted to be what the FIM class as Superstock as do ACU in the UK and the proposed privateer rules would be more like some 'Streetstock' classes.

Equally we don't have a 'Supersport' class in NZ as the National 600cc class is effectively more of a Superstock 600 class if you view it in the context of the FIM rules.

[Robert Taylor]

Obviously PP will be approaching you to act as Chief Technical Inspector (Suspension)......

Well, PP needs to approach SOMEONE that abundantly understands chassis / suspension and tyre dynamics because its clear by the proposed ruling that there is VERY LITTLE understanding. What I said previously wasnt neccessarily about spending more money. Consider the following;

1) If you are burning up tyres very often the solution is revalving to achieve better dynamic damping control. Springs will not always fix the problem and it is very very easy to overspring. AND HOW MANY RACERS ARE GOING TO BE PREPARED TO HAVE 2 OR 3 OPTIONAL SPRINGS TO HAND?

2) Crown Kiwi is the major spring supplier in NZ for motorcycle options. I can categorically state that spring options are readily available for the late model 600 / 750 and 1000cc sportsbikes. But we dont stock too many of these because it seems more people will buy a shock. Spring options for ( for example ) naked bikes and other models such as commuter bikes are patchy to non existent. AT NO TIME has anyone from MNZ consulted us about the readily availability of springs, youd think there would be some due diligence on that count.

3) High quality aftermarket shocks such as the product we sell are just not taken straight out of the box and bolted onto a racebike because the internal settings are calibrated for the road! We change the internal settings according to the racing application, rider weight and skill level and type of tyres / brand used. Engine power output is also a big factor in determining valving spec and spring rate. Of course, stock sportsbike shocks have internal damping calibration for road use...........

This is not a sport for cowboys, unfortunately that is how some of the band aid solutions make it look.

Guess i best go read it for myself !

AND, how are they going to police it?[/QUOTE]

This is always going to be the problem. History has shown that MNZ are piss poor at enforcement of there own rules and as most of the people who are capable of doing this job are directly involved or dont want to be involved any more there will be an even bigger gap between the haves and have nots as it will no longer be as simple as going to Joe (or DR) Bloggs and buying the parts to have the same as eveyone else. You now have to have knowledge and skill to modify parts without being blatant and rest assured you wont be caught unless MNZ is willing to provide money to pay for a skilled person to inspect these bikes. MNZ has shown that money and road racing don't go together from their side.
Also the loss of Paul Stewart is Very Bad for Elite roadracing In NZ
