Looking at sled prices today, the doo 600 carb seems like a great deal. How much Hp does it have? Anyone set it up with a holtzman ataac so jetting isn't something to deal with? How is gas and oil usage? It lists for a good discount to the efi 600 but I know that's different suspension, etc. Cat's 600's are all pricey, poo has the Indy but only in short track if you want a coupled suspension
