Hey. What is the stock jetting on the 2004 450r? I just got a new pipe and they said to run it with the stock jetting but i have the HRC so its different than stock. Right now the header is really blue. Does that mean its rich or lean? thank you!!!

If you have the hrc with the stock carb you should be running about a 190 main jet.
