Hey noobie, take a look at the Kawi site. They now have DFI engines to match every model of carbed engine. The DFI's though, have the same power in a couple of the models, but more power in many of the other models. My FX850 is 27, but the DFI FX850 is 28.5 etc. I could, and would have been on board for that if I'da had the choice.
