WORKSHOP SERVICES & FACILITIES.

We offer our 40+ years of 2-stroke engine experience, with preparation, performance modifications and rebuilds at very 
competitive prices.
All of our machining work is to the highest of standards, and engine building is legal to the relevant controlling bodies regulations, 
wherever you race. 

Ultrasonic Parts cleaner  .........  

This is just something to see,  carbs, alloy engine mounts or crankcases can be cleaned to look like brand new again  !!   
Even old carbs that have corroded due to the use of methanol and other exotic fuels can be cleaned up to look amazingly like new. 






Ignition testing ...........  

We are setup to handle Yamaha KT100S and KT100J ignitions, ( which covers the ARC also ),  so if you have
one that needs testing,  or you want accurate timing marks engraved on yours,  then we can help you.   Cost is just $30. 

Walbro carburetor tuning and modifications  ............ 
In 2006 we spent many hours out testing with our junior drivers in the National classes.  By the end of 2006 we were able to produce a better performing WB-3A carburetor with revised drillings and o'ringed throttle shaft.
A new carburetor with these mods done is  $210 ,  or we can do all this to your own carb  including a full rebuild for just $70.

CYLINDER BORE REPLATING
Most plated cylinders can be replated - Chrome/Electrofusion/Nikasil.
Also any damage repaired or welded and bore replated to suit the original piston and rings, either genuine or aftermarket brand. 
Chrome rings may be used in Nikasil® plated bores for long life.

Delivery time is only 2 to 3 weeks. This service is now performed within Australia with lower prices and faster turnarond time. 
( If you are wondering about the quality of the Australian repairs, a customer with a Rotax 125 Max has had his done here and so far it has
lasted through 4 pistons for over 100 hours of racing )

EXHAUSTS   
We manufacture 2-stroke exhaust systems from zinc-annealed or plain mild steel in 16 to 22 gauge (depending on application). In the case of motorcycles, Odysseys, 
gearbox Superkarts, etc, the pipes are made and installed directly onto the machine -- hence we need the bike, car or kart in our workshop for this to be done.

KART BUILDING & REPAIRS 
Our karting history began in the 1950's, with the late Bob Williams and a few friends making some of the earliest karts in Australia.  Today we no longer produce 
our own brand chassis, but rather prefer to supply the best that the industry can give us to help our customers find that winning edge. The preparation of any kart 
is mainly dependant on its intended use, so it is hard to 'quantify' such a process into a dollar value.  But here are some regular jobs that we perform that will act 
as a guide.  

Re-powdercoat a bare chassis  ...  must be stripped bare	$165.00
