Thanks tor the reccomendations.

rcpattern, I am going to stick with the 1.60 fx with a mueller header and tuned pipe. Perry pump.

F.imbriaco I wanted to keep it simple, as the plane had a 1.40 rx in it previoulsly all the plumbing is there for the 2 stroke.
also the 1.60 with header and pump still comes to less than 325.00
