I'm running a 4100, for jets, look on eBay, get a few different sizes, the factory ones will get you close with that cam, the power valve will need to be changed also, makes it kinda flood at low rpms , huge improvement thoe, I don't know how the intake sits but I know stock intake puts the fuel screws in a horrible spot, and you wont really need a choke, hope this helps, by the way I think I'm running 51 size jets
