We offer our 50+ 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.
2 stroke cylinder porting ........ Our many years of 2 stroke engine tuning includes our never ending work in performing cylinder modifications. We use porting tools that work, and with such a vast experience in this very delicate and demanding area we can usually provide a job that is the equal of anything from across the globe. Read more here ..... Soda media blasting ......... This is a method of cleaning all of the alloy parts of an engine and carbs that has been impressive. We can clean up most used parts, and even fire damaged and tarnished cylinders, heads and crankcases have been brought back to looking like new again. Ultrasonic parts cleaner ......
This is just something to see, carbs, alloy engine mounts or crankcases can be cleaned to look as new !!
Old carbs that have corroded due to the use of methanol and other exotic fuels can also be cleaned up. 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.
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. This was our 1612 version carb.
Thru 2013 we again went testing and with our team driver Ben Delaney made some improvements,
including an o'ringed low jet , and we now offer an NJ model carb with even better response.
And again we went back to redesign our modifications for the AKA and AIDKA classes using the
KT100S Yamaha engine and now have a new style NC standard bore version for the bitumen classes and
NC2 big-bore 27mm dirt carb .
A new carburetor with any of the above mods done is $199 , or we can do all this to your own carb
including a rebuild kit for just $89.
