A crashed Bucket

[Bert]

Stepped broke despite generous radiud, but Mike's million dollar made from scratch ones survived. Offset is what using now which undermines the seal surfaces and magnitude harder to setup than boring an existing hole bigger which is child's play by comparison. You have to go to 48.3 to run up to 52.3 could be .2 can't remember.

52x52 is just over 110% with no rebores either. 7% would be enough. That would be 133 for airs and 160 for bangers. Pretty close to now.

We are all in this together, I could go with 133 which would allow all four common 0.5mm (used to be eight at 0.25mm each but times have changed) oversize steps out to 2mm OS for the 125's and 160cc for bangers but I could also look at getting a run of cranks done for a real modest amount say $150 each (thats about what it costs me for a piston) would that help, probably need to do five units at least to make the setup cost worthwhile, would there be any serious takers do you think?

Anyway there are alternatives.

I've been thinking along the same lines for a couple of years now.
7% does offer the best across the board rebore options.
Keeps the 100s going
Opens up a few more 125 options
And the fours are happy too giving another oversize not currently an option...

But man if someone has a bloody cry about this again the next decade

[F5 Dave]

. . . we`ll all be on 250s, but they'll be diesels, like proper diesils.

No what will happen is we finally all agree on something and are all sweet until right at the last minute someone will suggest MX85's.............

I am for it.

I am hoping it will go something like this:-

70cc forced induction 2T
MX85
100cc 2T
100cc forced induction 4T
125cc air cooled 24mm carb 2T
150cc 4T

+7% oversize allowance for everything but the MX85's (they are plated bores anyway, so its cylinder replacements for them)

It might be hard to change things for the other classes this year but we could pull together and get the 100's their 7% and if we can't get the same for the others too this time then maybe next year we could all pull together and even the playing field with a 7% proposal for the classes that missed out this time and maybe it would also be time to talk about the MX85's too.

Easier and better than pissing around with MB100 cranks (or any of the 100cc cranks for that matter), what do others think???

explain to me again why the 4t would need even more cc's though

If it was to be fair wouldnt the 85's be allowed rebores as well?

[Yow Ling]

the problem with rebores, especially with the fxrs is nobody uses it first 3 oversizes and just goes to +2mm, one rider skipped over the whole rebore thing and added the 8cc by stroking.

[TZ350]

If it was to be fair wouldn't the 85's be allowed rebores as well?

Just talking about 85's is radical enough, looks like they are probably going to come in but it appears to late to do anything about them this year, maybe a good thing, gives us a chance to thrash the details out properly for next year.

[husaberg]

don't they all have nisksil?
Anyway I hate the thought of them they are wrong on so many levels..........

[TZ350]

If we can't do anything about it now, lets save the 85 conversation for a little later.

What is important now is the 100cc 2T's and their 7%, lets get this one out of the way first.

I've been thinking along the same lines for a couple of years now. 7% does offer the best across the board rebore options.

After Berts comments I am warming to it, everyone is free to make their own submissions to MNZ of course, but what is the consensus? could we support it as a group?

Probably right, but that's not the current rule change put forward to MNZ

[TZ350]

True, but if we support it as a group we might be able to get it across the whole F4 class or at least lay a solid foundation for next year for the capacities that missed out this time. Anyway I am warming to it.

The 107cc saying it was all about a couple of people but mainly me when it was obviously not,

Are you for real, you don't even have a bucket (possibly something hidden in the back of the shed, who knows). Sorry dude but you weren't even considered, hilarious that you're thinking this way though. Come on give us a

Well I'm claiming credit for crushing the 100 overbore nonsense last year, someone else will need to do it this year as I don't have a MNZ licence. Should be the same argument as last time, the rule should apply to, or benefit all. It can't be to the exclusive benefit of one (or two) bike owners who can't be bothered de-stroking.

We all love the "s" as it sends Husaberg in to a tailspin

....................
what I do have finished is the molds and dies for the head and the cylinders for a RSW about $7000 tied up with them that I was going to sell as rough castings at cost only for each and I can assure you none are going to anywhere near north of Palmy now.
other than the one I promised Rob . If you think they don't Kel exist ask Scott Grif.

[Bert]

As a long time supporter of the 80/85cc concept, I still see no real way to allow them without a control period, thus makes the conversation irrelevant.
Maybe a few more like Glens (people willing to race for no points) then we can make a true and valid decision.
