Hey there,ok,first off thanks for all the help,second,what are the stock jet sizes in the 03 P650? I was looking on Nyroc for examples but all the elevation examples are very high,my elevation is about 45.5 meters above sea level,so that would be approx 200 ft? What would be a good jetting for this elevation,i know,trial and error but i want to have a general idea as to where to start,thanks

well at 200' your stock jets will be 138f/142r. with the mods you have go with 142f/145r, that will take care of everything. your pilot screws should be in the neighborhood of 2 1/4 turns out.
