Yep seen it many times, Crank is not true/good anymore or at least your main bearings are shot. Could be just to much preload on the crankshaft caused this.
Look at the end of your crank shaft where it goes in the small bearing on the left engine cover and you may find some strange wear patterns. Seen this from 750-900 aircooled to 888-996 and now even a 1098.
Your in the Ducshop area why not have Mark Sutton look at it? hel'l give you the straight scoop.
