Well, as you might tell from my name (I am also known on other forums as Flickable), heavy handling is not something that you should experience for too long on the FJR. The Bin-O'-Facts used to have links to a lot of posts about ideal suspension settings, and it still lists them, it just doesn't seem to have the links any more. But, my personal favorite is by HaulinAshe and can be found
here. It's a good read, and although I have linked the first page, where he has settings for his '05 FJR, there is further tuning discussed for the Gen II later in the thread. I think it's worth it to read through all the posts, as it helps learn what others have tried and you may find someone's post that is more similar to your own situation that has settings that will work best for you, depending on your weight, setup and riding style.
Although I am located in Kansas now for a project I am managing, I used to live in NC and road the Blue Ridge Mtns at least once a month, if not 3-4 times a month
. Now, I just have to trek over to the Rockies, which is a blast, it just doesn't happen as much
