FCR and SSW MRD pipe, also get an intake cam from either an E model, or Hotcams stage one (cheap on ebay) and install the intake cam on the exhaust side, the base gasket is 3 gaskets thick, remove one of them, do the 3x3 mod and a JD jetting kit.

I think I used to run 14-44, for wheelies pick the bike up in 2nd, then shift through till you reach 4th, it'll stay up forever then.
