F4 and F5 Miniature Road Racing. (Buckets)

MNZ Rules. (Motorcycling New Zealand)

Appendix W - Minature Road Race https://mnz.co.nz/wp-content/uploads...Appendix-W.pdf

Appendix A - Championship classes https://mnz.co.nz/wp-content/uploads...Appendix-A.pdf

Appendix X - Technical https://mnz.co.nz/wp-content/uploads...l-Appendix.pdf

Fuel is covered in Technical 12 and Nitro in Technical 12e. So Pump gas and/or Av gas for F4 F5 and not Ethanol, Methanol or Nitro. Total party poopers.

Appendix D - Fuel specifications https://mnz.co.nz/wp-content/uploads...Appendix-D.pdf

I don't think i will ever understand the MNZ thought process.
they have classic classes but change the capacity to be outside of what was in the rules in those eras.
like allowing GP 250cc 2 stokes in F3 when the periods only allowed 125cc.
For f1 there is no allowance for 4t twins vs 4t 4's so its 1300cc 4's against 1300cc twins when thse era rules were 750cc 4 's vs 1000 twins

Rob, where does it say that ethanol is not allowed for buckets?

Rob, where does it say that ethanol is not allowed for buckets?

Good question, I may be wrong but I thought the specs (Appendix D) specified the amount of Ethanol permitted in petrol. So Ethanol at 100% is not permitted. Best fact check me about this.

Persionaly I would be happy with no fuel restrictions at all for Buckets.

Pump gas max 10% Ethanol is specified.

When I read my copy of Jan Thiel's Book he hinted it was hard to work with the Italilans. But I now understand he was playing it down.

I ALWAYS worked very well with the Italians, except rumi, who was a real piece of SHIT..... and the most dishonest person I ever met..........

No, rules say the maxim amount of ethanol in unleaded petrol is 10%.
It is there for allowed to run 85% ethanol in 15% LEADED petrol.
Ethanol is not banned outright, as I was led to believe, although methanol is.

Personally I think the less restrictions the better. But what if someone discovers a fuel that delivers 5% more power and costs 500% more than regular petrol? In the end everybody who does not want to be left behind has the same power again but now everybody has to pay five times the price. A fuel rule can protect you from situations like this.

Having said that, I am a huge fan of E85: more power than just about every racing gasoline I know of and at the same time easier on the engine and cheaper than regular petrol.
Too bad you seem to have to mix it with leaded fuel, which I detest.
