engine vibrations

[RiderTRX400ex]

416ex brand new build and engine vibrates a lot, counter balancer IS set correctly. it has a hotrods crank with new bearings, and a wiseco 11:1 87mm piston.. any ideas?

did this just happen out of the blue or did this do this right when u start it up from rebuild?
