One of the most overlooked hinderances to being able to flat-foot these bikes is the seat width. The seats are fairly wide which keeps your legs angled out. If you remove the cover and cut off some foam where your inner thighs contact you, even just a small amount, it makes a big difference in how low you can place your feet.
Aside from that, push the forks up in the triple trees an inch or so, and get some shorty shocks. Lowering blocks are available for the rear, but as Hush said they mess with the ability of the shocks to do their job well because it drastically changes their angle. I have them on my 550, but I'd take them off if it were my main bike.
