3 fairly simple things you should be able to do...
the first two don't require any new parts:
1. adjust the lollipop on the rear shock, depending on how much adjustment you drop on the back, you may wind up sitting low in the back, if so, you can go to #2
2. You can slide the front forks up through the clamps to drop the front down to get you lower and maintain a balance front to back
3. you can source an 09 seat, I haven't had a chance to compare them myself, but everything I've read say that the 09 seat is lower
you should be able to get quite a bit of drop between those three things... I went the other way and raised my 09 significantly to better fit me, I did options 1 and 2, and I did a variation on 3 by taking it to a upholstery shop that did a terribad job and so I wound up ripping it apart and going back to stock, but that is always another option too- having someone mod your current seat...
