The cheater MX85 argument. I might be changing my mind.

[Yow Ling]

No, no, no. That would mean more power, more heat, more problems. The damn things are too unstable as it is.

Thats why its unnecessary

[Billy]

You missed the full tunnel crankcase reed, low internal primary drive, Clutch made for abuse, and not just bridge port exhaust, some have aux ex ports....... thing is though getting these kids to cross over on a modied std frame mx bike anyone aware why the MNZ separates Motards and Road racers on street curcuits.......... Billy ...........

Thats a decision taken by the clubs re the street circuit,Although there is a handlebar clause in the Superlite appendix thay would prevent motards running in there,I have helped clubs around that by running F3 instead and altering their supp regs to suit,To be honest though there are a number of stewards that don't enforce the rules anyway,

Oh and I'm in no way connected to MNZ anymore,Greg Percival is now RR commissioner

[Billy]

It would be nice to have them tidied up, and the holes pluged!

BUT

Someone made a start this year with the fuel rule and look at the stink that caused

Yea,

I don't disagree,I'm just saying,Don't wait for MNZ to do anything about it,As it won't happen,The rulebook in its current state is unenforceable in most cases,I would have a very different approach when building a racebike for ANY class now after witnessing the joke that it is firsthand.

It wouldn't matter what was in the rule book and how it was worded people would still be saying that

Welcome to the dark side mate.....the ability to read - and interpret - the rule book is much underrated by bike builders but IMO it's bloody essential. A knowledge of how it's been interpreted in the past is a must too as precedents, once set, are there for ever....

that is why although I have no position on this question, I keep emphasising whatever comes in MUST BE ENFORCEABLE.

It might only be Buckets but it is still a competitive sport.

Attachment 297417

This is where I started and with some very limited hand tools.

Sure you can't expect to be a winner straight off but it is a starting point that is still pretty much open to anybody.

It was years before I managed 20 hp but I learnt a lot along the way.

I would LIKE to tell TZ all the real tuning secrets, but I am worried that if I did, given the fact that Teezeetreefiddys engine (apparently) is "overheating" and requires dubious cooling efficiency improvements, (at a "wopping" 15.5 P.S) if I was to tell him how to make more power, it may well cause a Nuclear Holcaust of biblical proportions as it headed down the back straight, causing widespread destruction,and global warming of unprecedented proportions.

I don't want that on my head.

Mind you, he probably still wont win a race.

There you go, I guess TeeZee figured it out for himself starting at a wopping 15.5 hp and has been trending up ever since.

Does anybody seriously think 30hp will be the end of it or that any MX85 would be safe from serious "improvement" if he got hold of one....

I can see why he does not personally care whether MX85's are in or out.

[Billy]

It wouldn't matter what was in the rule book and how it was worded people would still be saying that

Yip,

I'm sure they would,BUT when a grade 4 steward can't follow it anymore as the rules have been reworded etc by a panel of experts that clearly don't have a clue,It becomes more than a little frustrating and don't get me started on the nonexistent "Correct procedure" that the appeal committee consistently refer when upholdong appeals that they can't direct anybody to in the manual,Still this thread was about MX engunes wasn't it,Best get it back on track.

You need to build a bucket Billy, of all the rules buckets is easiest to understand

Plus more grumpy old pricks in buckets than any other class

[TZ350]

Hey!!! I resemble that...

Yea,We'll see where this MX engine thing goes,I happen to have a 2004 KTM85 hidden away somewhere with a blown crank and a coupla frames that might suit.

This is exactly my thoughts on the engine sourcing for the mx 85. Not cheque book go buy one for$1.5k, although if you want to drop the $$ on one fair enough.

I found the bike sketchy's engine came from covered in Shit & blown up in the back of a shed. After stealing the engine and electrics I bought a new piston for under $100. Then the Mrs got up the duff and our local bucket track got screwed so I abandoned the build and donated it to start this Shit fight. Haha, you're welcome.

Good lad

Hahaha,

The shitfight is no longer my problem,But it's def worth considering,Even if it means a whole new class it could encourage young Moto X riders across,But I doubt they'd turn up in the hundreds,Probably more like 2 or 3 max and I'm not sure we need the junior motorcross attitude in roadracing either,Theres been a couple sneak in that have come from that scene and their attitude sucks to be fair.

[speights_bud]

I have to agree with you there, we did the mnz officials training with a large group of the motox clubs and sounds like parents are the most dangerous part of the job...

Oh and back on topic, someone said it's really just 2 people who are pushing for the change, I think it would be fair to say there are a few others who are watching that just haven't posted about their interest yet. Up until just now that includes me.

[speedpro]

45 pages in less than 3 weeks - there's plenty of interest in the topic.

As usual there is never going to be total agreement. It might be worth checking with the race organisers to see if they'd be allowed out if anyone turned up with one. Seems like a possibility, in Wellington anyway. That would be a good way to determine their performance without all the hypothetical cow excrement. If anyone has a motor in Auckland i'd be interested in chucking something together for a bit of a try.
