I took this bike to the dealer and they could not found the cluncking noise said it might be the swingarm. Has anyone had swing arm problems?
Swing are doing what? Pop those chrome caps off the sides of the swing arm pivot shaft and check the torque on the nuts. On mine, their supposed to be torqued to 50 ft-lbs. Check your manual. Also check the bolts on the top and bottom of both rear shocks. Not sure what else could be wrong with the swing arm!!
If there is something wrong with your swing are pivot bushings (can't really imagine that but ...) I suggest that you upgrade to the True TracK ones assuming they will fit your bike. See this link:
