I agree balancing a two stroke crank is basically impossible and always has been.
the tungsten insert is a counter weight designed to do the above.
Resonation causes the engine to vibrate anywhere between say 5000 & 15000 rpm by using a counter weight it would shorten it to around 5000-10000 or something like that.
a good example is HONDA they use a counter weighted cam shaft to offset resonation at 3500 rpm .if they cant balance a crank how is it max power can?
