Wow, after paying what most woukd consider an extreme amount of money for what is supposed to be a quality motorcycle & then having to strip the engine to repair something that should be basic quality control from the outset. Does my head in !There was a thread here awhile back that dealt with elimination much of that engine vibration your friend referred to.
It was corrected in part by proper balancing of the balance shaft, which was out of whack.
The other issue was the crank, which was seriously out of alignment, probably because the centre bearing mount was attached with incorrect cap screws (too long) that bottomed before tightening the mount.
Once those things were corrected, the engine vibration level went way down.
It does require a full engine strip and dynamic balancing.
The cost wasn't great as that owner was able to do all of the disassembly and reassembly work in his shop.
