Just had it done, 250 miles ago. It was really hard to do such a great bike with 2 wheels. I still get my curves from my 85 k100 and 08 RT. Anyway the deed is done and I am still getting use to g force wanting to eject me. To the question I have, I hear a distinct HOWL when the load on the drive train is at a certain point. Say at 55mph 4th gear and at 65 in 5th.Go above these speeds or slightly below it will dissapear. I should tell you I did not notice this before the conversion. Also I purchased this motorcycle with only 980 miles on it. It has around 2000 now and many more to come. With 2 extended trips planned for the fall. Thanks JIM.
