The very first place to start is to try, try being the operative word here, to set your loaded sag on the front and rear of the bike. Obviously, the front has NO adjustments, so the only way to change the loaded sag up there is to get into the forks and "adjust" the spacer that is on top of the springs....by either shortening it (if the front is too stiff) of putting in a heavier set of springs if the front is too soft.
The rear has an adjustable preload for the shock. Loaded say is a personal preference for most folks. I like a bike's suspension setup to be a bit on the stiff side but for many, and a good place to start is to adjust the rear shock, either increasing the adjustment collar or decreasing the adjustment collar until you have 33-35mm of sag when you are sitting on the bike with all of your riding gear on.
There are numerous articles on the internet about how to check sag on a motorcycle and it usually involves yourself and a couple of helpers...to take measurements and hold the bike while you sit on it.
Front sag, if you decide to tackle that job, a good starting place for an "average" setup is 38 to 40mm of loaded sag, but as I said, that one is going to be more difficult as there are no adjusters to turn.
