Depends on what is done to the cylinder, and what compression you are running, as well as what ignition and whether the timing has been advanced any, as these factors all affect jetting.

However, somewhere around a 180 main jet, with a DDJ needle middle clip, 50 pilot, should get you close.

stock cylinder and 38 i would say a 170-175 would be more likely.
