The JD jetting kit sold here on TT, it makes an outstanding motor run pretty close to how it should (with the other free mods). No guess work just follow the direction.

175 main , JD Blue needle in clip #5 , 48 pilot jet, 2 turns on the fuel screw, 72 starter jet, 40 leak jet, should work well for winter riding in Michigan. :cry:
