random question, yes its stupid!

Very true....even though my blaster isnt even available for me to do anything to it...);
I would compare the power increase to running a sbc or bbc 1 qt low on oil so the crank isn't being slowed down when spun around into oi....not much and not worth it
How would the stator work if balancer removed??

what if you just machined off the balancer weights and make it a round shaft ? There would still be some rotating mass, but you could probably lighten it to the point of none existence.

The balancer in the case, not the flywheel. Most single cylinder engines need a balancer due to the crank and piston throwing their weight up and down so a balancer throws its weight in the opposite direction evening things out.

in his sig it says he has a lightened cuonterbalancer. maybe we could ask him? im gonna guess and say chutzel did it for him.

Here's what I know (and it's not much). I spoke with two shops that balance cranks. Neither one of them need the balance shaft to balance the crank and both of them told me not to mess with it. I know of two members that removed the shaft and had major problems with vibration. The people in the know are going to be the guys that have tried this. I haven't. I'm sure the counterbalance shaft is making up for the unbalance of the crankshaft. If you assemble the bottom end and turn the crank over in the case without the counterbalance shaft hooked up, it doesn't turn smooth. If you do the same thing with the counterbalance shaft, the same thing happens. When you connect the two together, the rotating mass becomes smooth and balanced. I'm sure some material can be removed but I can't tell you how much is going to be too much.
Some times the inherant design of an engine can't be changed. I would think Yamaha designed it this way to reduce the 2 stroke buzz more than with just crank weighting. Do 3, 4 mil cranks use balance shaft? If they do they should have been designed to eliminate it, because at that point of modification extra buzz would not matter. JMHO, your results may vary.
Thanks so much Ken! Some green for you! I dont know why dirtbikes don't have them, there has to be an exact reason? Do V-twin atv's have them (brute force 750)?? Seem like having a V set up would cause the motor not to vibrate so hectically...
