I figured that would get to you.Look at the 2012+ forum to start with. Asking about a 2012 in a 2004-2011 forum probably won't make much difference but it bothers my OCD.
I am not aware of anything "wrong" with the the pre 2012 DL-650s. I own a 2007 DL-650 that I purchased new. I have over 100,000 miles on the bike, and I haven't had one problem with it.I want to know what I should or shouldn't be doing with my 2012 that owners of 2012 wee's know nothing about.
