Up to 110cc can be water cooled, but if greater than 104cc then restricted to 24mm carb.

Yes but if this is all the rules it dose not mention air cooled. That would mean you could have a water cooled 125 with a restricted 24mm carburetor.

I obviously need a coffee as I can't find the rules on the MNZ site at the moment
You're looking at the rule change for chapter 24, you need to link the rules and appendixes together for the full picture.
The F4 capacity is defined in chapter 10 (maybe?) and read
F4
2 stroke 55-100cc
2 stroke 55-125cc air cooled
4 stroke 55-150cc

here is the rule effective from Aug 1 2015
Chapter 24 – Road Racing – Miniature
24.2 - Engines must be derived from non-competition motorcycles. Motocross, Road Racing, Enduro and Go Kart motors and transmission parts are not permitted. There shall be no restriction on the make, type or design of carburettor, ignition, exhaust, piston, cam, valve springs or cooling system except for class eligibility. All engines must be normally aspirated except F4 4 stroke engines of less than 100cc capacity and F4 2 stroke engines of less than 70cc capacity, which may be turbo or supercharged. F4 2 stroke engines over 104cc are restricted to carburation equivalent to a single 24mm carburettor, F5 4 stroke engines over 53cc are restricted to carburetion equivalent to a single 20mm carburettor.

AWESOME! So you can build a big bore water cooled engine run it all season, but you cannot contest the F4 GP with the same said engine

The rule book, sorry MoMS, has had that many amendments and copy and paste hatchet jobs that it is really due for a full over hall and reformat

Great, now I have to check with my Mom to go racing

I think the restricted carb would have been a deliberate decision, 110cc water cooled, open carb would make everything else obsolete.

Really Kelly? just how many hp do you think 6cc will make...........
1.5-1.6hp at most, wow.
It could have been deliberate if they hadn't forgot to change appendix D.
It does prove that the MNZ doesn't understand the rules for the sport they are meant to govern.

wish people would stop pissing with rules , if you do one thing it should be across the board

Maybe a few of us need to get together and have another go at this.
My past experience of writing the special event licence submission: was that it was a mess to hook it all together.
But in this case only Chapter24 and appendixD.
Chapter24 needs breaking into solos and sidecars.
Construction needs linking to Chapter10, but defining what requirements are required.

I vote sidecars get twice the capacity because two people. But only for me and Rick.

[Pumba]

I vote that all bikes + rider must have minimum combined weight of 200kg

Totally agree. The oversizing 100's was a total piss take but its gone through so I intend to exploit it.

You have it all wrong (now why would that surprise me) 110cc water cooled is fantastic, no other motor in the class will stand a chance against ours.
Air cooled MB100's pfft, Derbi 80's , 150 four strokes

ESE 110cc water cooled game changer Game over

Maybe the game needed changing, has been changed before, will change again
