J stands for Junior engine and S stands for Senior engine.
classes with *** next to the engine are allowed to use the ARC engines (water cooled) but I believe and i may be wrong at this but i believe they have been thrown out of several classes this year and formed their own class..which is fine by me..those things are hard to catch during a long race.

clubamn karting was from what i can gather set up to keep costs low,,it had rules in place that allowed minimal modifications to the engines therfore equalling the competition as well..but sadly of course the cost has skyrocketed over the past 5 to 6 years ..it was meant to be the class for guys that just wanted to race karts and had no ambition of going on to f1 or moving into any other from of racing..keep it simple and cheap and more people will join..but sadly the AKA are losing members all the time because of rising costs and silly little rules that keep popping up.

For the rest of this year senior clubman can run the ARC Spec 100A (aircooled) but as of 2002 it is back to KT100s only. Junior clubman can run either ARC watercooled or KT100s

Formula Australia is the class for the ARC W and watercooled yamaha (using ARC head). any chassis is allowed at present but in 2-3 years it must be an Australian chassis and components. This class uses different tyres to clubman.

The big problem for me in Sydney is trying to get a race with my ARC W as the clubs i have contacted (NSKC,NKC,SKC)don't have a FA class.

thanks kartracer..I knew they were planning something about the ARC's..but i didnt know if they had done anything yet.

good luck in finding a race ...i know not many guys in our local club have the ARC engines and are also having a few probs.

ok thanks i have a kart but now im not sure what engine it is. If its any help it has 4 bolts for the head. Im almost 17 so if you would know what motor it is then what class would i be in?

Thanks

Hi HRT kid

the best bet would be to take the kart/motor to a kart shop or better still an OLT (observed licence test) or practice day at your local track. If you go to the track don't be afraid to ask people as i have found most karters are only too happy to help a new person...

If you have a digital camera or scanner you could take a pic and post it here... maybe we might id it for you...

Here in Tassie we race a sub section of Senior National for drivers over 40 years of age.

This is really good because my son and I can share our kart.
