I see kits to eliminate the balance shaft online. Is this recommended, or will it cause vibration? I know my old engine was rebuilt before I bought it, and it always had a buzzy vibration over 2500 rpm. I haven't torn it down to check, but could this be an issue from eliminating the balance and silencer shafts? What benefits could come from this mod? I am going to start reassembly of the new engine in a couple weeks, so now is the time to know which way to go.
