[QUOTE="wfooshee, post: 1061160, member: 6354"] As to why the balancer isn't helically geared, helical gears introduce thrust loads. I've seen discussions of the ST1300 foiks "smoothing out their bikes" by "adjusting the balancer," but as Alan pointed out, that external adjustment has absolutely dick to do with the actual balance function. The only way to "adjust" that is to remove the balancer and put it back in on a different tooth, which of course will make it worse. That adjustment might make the balancer run quieter, but smoother? No way. But if placebos make you happy, then load up on 'em! Also, hppants, there is another balancer on the rear of the engine, accessed from the top, a four-bolt cover plate in the valley between the cylinders and the tranny. You'd have to turn the motor back over, set it upright to find it, so you probably aren't too interested in it right now....
