Well, after having starting problems I ordered a Keihin 42 pilot jet. When I was putting it in I noticed that the pilot jet already in there was the exact same size but was marked a 38. Are the jets supposed to be the same size? or is the 38 made by a different company and is actually the same size jet?
The bike might have been jetted by the previous owner ('04 400ex) is what I'm thinking.
The pilot jet marked 38 that came out had this type marking at the top along with the number 38. The main jet is marked with the same marking and is numbered as a 148. Ideas??

Edited to say that the bike is 100% stock, no intake/filter/pipe/etc.
