So there was a old thread about someone who removed the counter balance shaft. Last update there it was good after 6000Km's . That was on a 470 mod engine. In the last 2 years on 06sm models I have seen (with Loctite fixes applied) the CB shaft get ejected out the front of the crank case. Mine has chewed up the key on the shaft and started hitting the crank intermittently. I suspect after 45k miles the cush springs on the gear that drives it became weak and allowed for it to be out just enough to cause the damage. Has anyone else removed the CB shaft from their engine? How long have you run it this way? Did anything bad happen? General Thoughts? I know it will vibrate more without the CB and the bearings have to be removed.
