Hi all,

I was thinking of trying some castor instead of full synth in the next kart. Thoughts about this in freshened up old mower engines ? Chippo ? And what about the Mc10 ? Also, how clean do they need to be of one before switching to another ?

TIA, David.

Yes he had to gear it right down as it was so fast in practice at Newcastle the tyres were growing off the rims   LOL I guess I had better shut up as we have not finished a meeting for a while

Interesting comments. Just go back to the future, like me.

(Page 2)

Not all classes have to be 100cc, surely? PRD make a great 125cc engine for under $1300 rrp. What about the return of large single and/or twin engine classes? A twin Yamaha KT100S or PRD 125s would be very attractive and could be on the track for about the cost of a current KA1.

How about all new karts be Australian made? BRK, Benson, Arrow, etc.? South Australia has a distinguished history of making karts for Australian racers and recreational use, as does St George in NSW. Australia is also fortunate to have a number of component manufacturers here and producing cost-effective components for club-day racing would be no more problematic than a few emails. Surely?

Another argument that never seems to be settled and that's tyres. Many people complain that the old tyres where too hard and offered no grip, but that's ignoring the fact that the old, hard tyres demanded far less on the chassis and also took a lesser toll on the kart's components. The hard tyres also provided the bonus of less physical stresses, which is very important for young drivers, as well enabling older drivers to stay driving for longer. There is also a major cost benefit to be had. The much-maligned Cheng Shin tyres are still a fraction of the cost of the major tyre manufacturers and can be purchased almost anywhere without the impost of a tax from Karting Australia. Not only are hard tyres cheap to buy, but, return to a tyre that lasts almost a season would make karting far more attractive to prospective members.

Tracks don't need to be of international lengths and standards. My local track is a grand affair with all the latest mod-cons and facilities - but you hardly see anyone there using the track. With the exception of major meetings and poorly attend club meetings, it's a ghost of a facility. No weekend putterers playing with their latest creation. No vintage karts test running. No four strokes. No nuthin'!

Rather than having the latest technology with a vision of F1, why can't people agree to having a more rudimentary form of four-wheeled fun? Simple, cheap & FUN!

Couldn't agree with you more Max Laybutt!      (Page 1)

Even when you don't take into account the oligopoly of the current regime for over-priced engines & tyres, the use of things like hollow axles in various tensile lengths, vented discs, variable track/s, exotic metals such as magnesium, the arguable use of bumpers all-round, carbon fibre seats, etc., etc, add to the enormous cost, complexity and weight of karts.

There is no easy fix as the opinions vary enormously, especially from people who raced era 1, 2, 3 & 4 karts and believe that club karting can/should be for the hobbyist - separate from the Formula One aspirants that dominate the ranks of racers and administration here in Australia.

There's practical ways to reduce the costs for hobbyist karters, but the ideas are always polarizing. Plastics are a good example! There is no real reason why hobbyist's karts should have any plastic bumpers, and yet the old chestnut about safety is always raised and used as an effective rebuttal to those who want to return to a more simple form of karting, despite there being no empirical evidence to prove it. There's as much evidence to say that bumpers actually worsen driver's behaviour, rather than fix it!                        

Consider the structure of a simple kart. A return to to small, solid axles in mild steel, with keyway'd non-adjustable track wheels Simple - cheap!                      

Have karts that fit within a 6'x4' trailer to have an effective restriction on kart dimensions and remove the need to have huge karts transporters and promote the use of the cheapest trailers on the market.

Why not bring back the original ideas of kart engines - sourcing cheap, common and effective engines and with liberal tuning ideas in an open class, to promote home-engineering that was so prominent in the '60s.                                          

Club day only engines should be based purely on costs. Why is Karting Australia using a $3000 engine when there are plenty of new engines for about a thousand dollars and less (PRD, Yamaha KT100S/J, etc). And what about the utilization of cheap generic engines - both 2 stroke and 4 stroke?

Why aren't we incorporating old, redundant karts as a cost-saving measure? The market is awash with old karts worth a few hundred dollars. Surely an age limit (not too new) could apply to karts!

We have seen the demise of engine tuners and kart sellers across Australia, who have an enormous amount of ability and skills and we are about to lose them because of this oligopoly with engines. With the return to more liberal tuning rules and the reliance of equalizers, such as restrictors (inlet & exhaust), and/or the freedom to choose motors free of import restrictions for more exotic classes (motorcycle engines - enormously successful on speedway karts), tuners/shops can flourish.

Just on another note,

Son bought the very latest Marenallo, with all the good gear, and then bought and coupled a known performance Rotax onto it, Total Cost $OBSCENE.......

Now my comment is, .................. "it is a long way from what us guys raced for one hell of a lot less $'s"

Not sure Modern Karting is heading in the right direction? ...... But that's the young peoples track now?

You hang in there Maxie, they all said you can't have moving pictures coming out of a box in your own lounge room once; Hey.
Comment by Tom Manley on February 9, 2018 at 9:20

Max you better safety wire that and hold your breath. Or take some lessons in gas brazing.


Comment by Mike Burrell on February 9, 2018 at 9:19

Don't you worry about Tom... he's just a bit cheeky.  At least you have a go.. So with this modern technology you have we will all be watching!  I use JB in a few areas of the Victa with no issues But just for filling not welding....  good luck Max. See you on the track.
