I ordered my cover gasket and in the meantime I was thinking is there any way that I could get my new updated version rotor balanced?? I've heard several people having the bearings go bad and it seems like a rotor that's not perfectly balanced could lead to this. So while I'm waiting on my cover gasket I figured I would check into getting my new updated rotor checked/balanced if needed. I wonder if there is anyone who does this?? I'm thinking of calling a local engine rebuilding machine shop. I'm a CNC machinist myself in the lathe Dept but we have nothing for checking to see if this baby is balanced. I did check the runout on it and this baby looks to be nice and true.
