I am looking for input about balancing cranks on non-counterbalanced two stroke engines, especially CR and KX 500s. I am trying to find out how much they reduce vibration when placed in a quad frame. If there is one thing that most people will learn about me, I ask a lot of questions, and I constantly come up with many different ATV projects. I am coming around to the idea of a KX500 powered quad again (I've wanted to build this for years but couldn't afford it), so that's why I am asking about crank balancing. A KX500 could shake so bad that it kills unborn children, and I don't want any of that. If worse comes to worse, I already have blueprints drawn up for a rubber mount system. I just want something very different from the thousands of Hondas I see everytime I am at the dunes. Plus, I'm a Kawasaki guy, and I'm sick of not having any good "true" Kawasaki powered quads, excluding the V-Force. I don't want a V-Force because of the auto tranny or a Tecate because thay are too hard to find parts for. Any help would be greatly appreciated.

 

Can't answer that question, but have you considered using an Invader or Intruder sled motor? Sled motors just seem to rock 'n' roll the best of the 2-stroke world. If I could afford to, I'd love to put a Polaris 500 power valve twin in a Scrambler frame. Long live the mighty 2-stroke!
