I'm not as tall as you (6'1"), but I've got a 35" inseam, and I ended up getting a custom Corbin, raised 2" and the seating position moved back about 2".... that and the footpeg lowering blocks by Speedy made a huge difference.
Ended up doing a self mod for free which involves stuffing the seat with foam through a hole under the seat.
After the forward slope is fixed, put on the better Airhawk and never looked back. Most comfortable seat I've ever had! Easy to change out too!
Take it off if you sell your bike or put it on a different bike to ride! Awesome!
I would say total gain about 2 inches. I'm about your height.
Gents many thanks for the replys, in 2 rides I have put 250k on bike I have got the Motowerk peg lowerers, need to get 2 x 19mm spanners
