Mine has had the clunk going into 1st when starting out. I found that operating the clutch a few times and holding it disengaged while warming up and then shifting into 1st gear, it goes into gear as smooth as silk. The dealer had to replace my cush drive also. I also have a small amount of clunk in other gears and going into 1st after stopping and starting out again. I have only a little over 1200 miles on my bike and going to change the oil to the recommended Mobil 1 syn oil. I have heard that or Amsol will also make a difference along with more time on the road.
