So I am all over the place right now with what I should do next to the XX. I have been talking to Daniel from High Desert Dyno and from lurking on the Modded Raptor forums I know that he can build a fast bike the right way. I had my mind made up to go with the 727 big bore, wet sleeve, and the 13:1 CP piston but when I started talking to Daniel he was saying that he thinks that set up will gain about 5hp across the board. I was thinking with the mods that I already have and the 727 kit I would be into the 70hp but it looks like it will be more around 65-68hp. If I go with the Boss Noss setup I will be about 61-62HP on the motor and 80HP on the bottle. What do you guys think?
