My setup for trails and dunes which I LOVE. And it rips.
35mm Kehin PWK's with K&N pods and billet intakes. VF3 reeds. R&B Racing dune port (Choose builder of your choice, of course), stock stroke, 0.040"over, 19cc domes in a Trinity Head (185psi, runs on 110 octane). CPI inframe pipes.
This setup has proven to be awesome in any riding environment. I thought the carbs would be too big, but I noticed a nice increase in "seat of the pants" power when switching from 28mm's.
Good luck!
