Australian Karting Forum

For anyone who hasn't seen the email, there are a few changes for cadet 9 club/zone competition for next year:

  • No Mychrons/data loggers permitted at all
  • No magnesium wheels
  • Only a #97 jet permitted
  • Only 72, 74, 76 and 78 sprockets permitted
  • Axle length between 920 and 960mm
  • Axle diameter 30mm only, with max 4mm wall

These restrictions don't apply for state/national rounds.

Thoughts?

Not true, you can also get a 12T (its on Ian Williams Tuning price list for Mini ROK) but I suspect a 9T is not made so unlikely we will get a result there.

I had the same thought as you and rang Stones Bros today to ask about getting a 9T, and Ian told me that Rok only manufacture 10 and 11, therefore they are the only ones approved. ??

With all of those things considered to me the most disturbing are the new practice rules. When you read appendix 1, Private Practice Rules, the last section Practice Sessions states :

It is forbidden to cross the Track, sit on tyre walls or be inside the Circuit while ever there are karts driving on the Track.

So how can a father provide instruction and guidance to a learner driver if they cannot be anywhere near the track?

Hadn't read that. Ridiculous.


 You could flag the session once they fix the wording of the rule to allow flaggies during practice..........

I think KA need to seriously rethink their decision on data loggers.

- the data logger is a great tool to teach the kids about braking and acceleration points
- even basic set up of the engine at various tracks requires use of a data logger
- how do parents learn to use the equipment if they can't use it - particularly when the time comes for State and National Round and when they progress to 12s

There is so much wank around the tyres - you can easily get 3 club meets out of a set of tyres. Learn to set the kart up!

Some tracks wear the tyres a lot more or less.  Also the speed of your driver and the level of competition and if qualifying is being used are big factors.

Easy fix at the club level - don't use a format for the Cadet 9s that involves Qualifying.

Have just discovered that there is no compliant axle available to purchase for the DPE (Arrow/Deadly/Sera) cadet karts. The closest they make is a 960 x 30 x 23. i.e. it has a 3.5mm wall when it needs to be 4+ mm. The alternative is get a 1000 x 30 x 22 and cut it down to 960.

I wonder if KA actually looked at what's available before they set the rules.

Get real. But there is bound to be one available from someone in the inner circle.

Same with rear sprockets. Heard at my last ever KA sanctioned meeting that C9 requires an 83T sprocket as standard equipment at their home club. Tight track with long uphill section.

But if any of the restrictions were sought out from clubs, that would have been a first from the new dictatorship.

At least a few years ago, all proposals, no matter how silly, were debated by at least some clubs, with instructions passed on to the state delegates and other committee officials before each national conference.

getting rid of wets would have been good. I saw about 10 cadet 9's that stuffed a set of wets on the weekend at Swan Hill because the track dried out.

I didn't have wets when I was a kid karting and we survived. It would have been good to keep the mychron because I too have already purchased one and they aren't that expensive.

I do think the Vortex Minirok should come in around $1200-$1500, I can see a lot more people buying used karts and perhaps getting a used package for under $3k
