Feb 09 I bought kits from nearly every supplier. 2 were exactly as you describe. The vibration was so bad that the bike was not rideable.

I took them apart and found that the holes for the con-rod, (big-end), pin had been drilled out of square to the face of the crank. This essentially mimics a bent crank condition. There is no fixing it, or balancing it. You'll need a new crank, or a new engine.
