Can someone help? It looks like fuel is open for pre 72 and pre 89 two strokes and restricted for pre 82, am I reading this right?

If pre 72 & 89 fuel for two strokes can be open, why not for pre 82, who benifits from this restriction in pre82?

Should be open for all?

You might want to read the whole set a bit closer and then look at the rules the additional rules referred to a bit closer.

The pre 82 and Pre 89 rules on fuel are the same.....
Both say 2 strokes as per rule 10.17.1 which is open to racing fuels only up to certain characteristics of avgas or FIM unleaded (ie not limited to pump).

Looks Good.:wari:
I have run my 89 GSXR1100 at a couple of there meetings and had a ball.
The pre 89 allows for some good old fashioned budget racing.
e.g. my ex-wife got all my money.:whocares:

"25-6-4: Forks
White Power and Ohlins had very limited supplies of USD forks available to special teams on their works
or works issue motorcycles.. These specific forks may be used if originally fitted to the bike in question.
(eg 888 Corsa Superbike). The onus of proof is on the rider."

Bye bye half the pre 89 field.

Does it? I've not noticed any ohlins, white power forks on pre 89 machines, but I'm a little out of touch on what bikes are floating around up AK way.
If people are running forks from later models of their machines - then tough bickies, they were already breaking the spirit of the rules.

It does not affect me, my bikes only mods are slightly heavier clutch springs and a muzzy exhaust, other than that, bone stock.

Funnily enough, I'm working on my bike right now :yes:

YOur quote above is missing a bit - I think the full rule reads:
25-6-4: Forks
Upside down forks are prohibited unless originally fitted to the bike model in the period. Forks must be period items. Internal spring and valving modifications are permitted.
White Power and Ohlins had very limited supplies of USD forks available to special teams on their works or works issue motorcycles.. These specific forks may be used if originally fitted to the bike in question. (eg 888 Corsa Superbike). The onus of proof is on the rider.

This means that one production model which did have upside downers from the factory - ZXR400's can have them.

That's the only bike found which has good real proof of being legal with USD's. Others may exist, just means that the owner has to find enough proof and I haven't seen any yet

This rule basically says:
1) the said bike can use those forks, but the forks must be the oem forks and fitted to that model (ie no NC30 with ZXR forks must be ZXR forks on ZXR bike)
2) Should someone front with a factory 888 or like which has period Ohlins fitted is okay ( I have magazine tests by cathcart where both the 1988 Factory Bimota YB4EIR's and 888 had Marzocchi and Ohlins USD forks fitted which proves they were used on those specific bikes)
3) That later model USD forks are otherwise banned in pre 89.

So either bikes fit in the above options or they are burgling it anyway and as Sugilite said - tough bikies.

Makes sense to me

I only quoted the relevant bit. Yep, there are quite a few pre 89 400's running ohlins etc.

Doesn't say nowt about swapping engines from other model though :-)

Shock or forks?

Shock is fine as it is technically not a major component.
Fork: Can't say I have seen any Pre 89 400's with Ohlin's front forks. If they did there is almost totaly probability that they are later than 1989 forks anyway. ie majorly illegal!! Forks are a major component and thus must comply with the specific cut off dates for the age group (this applies across all postie classes) would make them not eligible for Pre 89.

The rules being set to mimic as best as possible who the bikes were at the time. Late model out of period Ohlins forks sort of doesn't fit with that!!

So if they have them fitted thus far there's been a bit of "legal burgling" going on, given there were no formal Pre 89 rules prior to this and I doubt anything in the Supp regs stating what was legal. Introduction and formalisation of a properl set of pre 89 rules will/should eradicate this behaviour. But up until now it's been somewhat open as there has been nothing to enforece again, so people take the piss a little.

Seems you guys have got a handle on what the rules actaully encompass anyway.

Cheers

IIRC forks were never alowd to be changed to post what ever year, Im refering to pre 82 where I know of some bikes that do ues later forks :bash:

Wheels I disagree with, modern 17" and slicks I cant compete with... but its allowd, right off to read of these proposed changes.

1. You can protest the rule-defying forks, you know.

2. 17" and slicks have been allowed under the MNZ rules for pre-82 Open for years. Recently changed to allow for the smaller machines, too. Rules 25-4-2 and 24-4-3 now.

That's to do with availibility rather than anything else, because the forks they are using are just as crap as the standard ones

They were just as crap as the standard ones, they were only used because it was the cheap option rather than rechrome to fix a continually leaking fork seal

You could buy emulators or even try different oil /spring/ oil volume. Just because you have a handling problem doesnt mean it cant be fixed.

If you're not prepared to protest, you shouldn't whinge, then.

The protest was designed 100 years ago as the only proper way to deal with a competitor's tech infringements, and it still is.

regarding engines etc..

Nowhere does it SPECIFICALLY say that the engine has to be from the original bike right, so if I was to get say a pre 89 xr650 motor and bang it in my 89 spada would that be ok ? Any thoughts ?

Or would that be not keeping with "the style of the time" or somethin like that

Yup I've been over the mnz rules before, for f3 and the new post classic page, I think I'll go ahead with it and if I get absolutely thrashed by everyone I'll probably put it back on the road mwahahaha.

And start a club "hoons r us"
