    Question engine balancing % ?

    If you run lightened rods and a lighter piston what is the weight ratios for the crank and balance shaft ???

    I wanted to know this myself so we asked Les Cooke and he refused to tell me the balance factor. He did offer to balance it for me at a considerable cost plus the cost to freight everything 4000kms aswell. I then told him to stick his secret balance factor where the sun don"t shine and took it to our local guys who do heaps of High performance machining for us and they worked it out quite quickly.You could probably get it from Rotax aswell!!!!
