I would definitely recommend setting the sag as above. It'll sort out weather the springs are correct for your weight. As mentioned most manufacturers set the bike up for a lighter rider. My KLX 450r required new springs front and rear for my weight. As did the KLR.
I read Rusty's post a few days ago so I don't recall if it was mentioned but when you do set the sag it's best to have all your gear on and anything you will be riding with on a regular basis. It's also a good idea to give it a few bounces to find where it will sag while riding. Also take several measurements just to be sure.
I too have noticed that the front washes out more than I would like, but I haven't set the sag on my ride yet either. I want to get the rally raid tanks up front before I do that. I really wanted the safari tank but I think it'll mess with my tank bag too much, but that's another story.
I also wonder about the front tire. Could that be a little bit of the issue? I know I noticed a big improvement when I put a K777 on the KLR. At my first tire change I plan to go the same route with the 690 as I have on the KLR. A K777 up front and a D606 on the back, man I love that combo.
Just some thoughts for you. I personally enjoy working on the bikes nearly as much as riding them... especially when you can see the results on the following ride.
Thanks for the forum Rusty!!!
