The Clone engine is a copy of another engine that is made in a country that has a cheaper labor component that use a majority of unskilled labor that workers are not covered by an award, workers work for a minimum wage, have no work entitlements, no unions, minimal or no quality control, that produce copies of parts or engines designed by other manufacturers that look the same.The big question is are they made of the same material, have they under gone many hours of testing & development ? have rotating parts been tested & spun at high rpms for extended periods of time. These engines when used for what they were designed for can work ok.They were copied for low revving lawn, garden & commercial engines to run pumps, & once the governor has been removed & they are used at high rpm with standard conrods, valve springs, flywheels & non graded soft bolts you have your self one dangerous package that could self destruct at any time.
When considering the cost of getting a clone engine for use or a gokart or any other type of racing application by the time the components like flywheel, conrod, valve springs, collets, retainers & crankshafts are replaced to bring the engine to a safer standard like purpose built racing engines like the Animal & World Formula there are still other parts of the engine that were not designed to be pushed to the limits.Engine blocks & cylinder heads that dont have thicker ribs to handle the additional loads,forces & stress that racing engines are subject to.
Do the sums the Animal & World Formula are supplied with reinforced blower housing, billet aluminium flywheel, squeeze cast or billet conrod, forged crankshaft, high quality bolts, high quality valves & valve train components, dedicated tooling for motor sport engine blocks & cylinder heads.
Dont get the wrong idea the clones do have there place, when it comes down to it compare apples with apples when things are cheaper there is normally a reason
