I just got an 09 RK/C. I am going on three hanger brackets in 1300 miles in an month all on the right side.I have slip on V/H. Any body had the same problem

 

You didn't say what the problem was.

 

Are you talking about the hanger bracket that connects to the saddlebag support? Because if you are, there is something seriously wrong with the way your header pipes line up with the muffler to create that much stress to actually break them. This is the first I've heard of this problem. I'd be back on the dealers doorstep looking to have them solve this once and for all. One of the header pipes (or both) could be out of alignment and when it's forced to have the muffler attached and bracketed down, the motor movement creates stress that might be causing your problem. Let us know what the solution is.
