04 CRF 250X Jetting (Help needed)

Recommended Posts

Hi I have a 04 CRF 250X with the following mods done:

AP mod

Baffle removed

9 (.75 inch) holes drilled in the right side of the airbox

250R cam

and soon I'm going to cut the whole top of the airbox off

I'm wondering what jets are in my bike stock, and what to put in when I cut the top of my airbox off. I have not had the chance to take this bike for a rip since I did the AP mod, drilled holes in the airbox, and put in the 250R Cam. I want this bike to go like hell in the spring when the snow melts, so can someone who knows what jets I should put in please tell me? Thanks!

Also I'm 465m above sea level

Hope that helps, remember ideal jetting will change based upon conditions (alt., temp, humidity,etc.). That is why fuel injection would be kewl. I think a 135 main is what comes stock.

Thanks for your help, I will see if my dealer can get me a JD kit, and I will go with your jetting specs. as you seem to know more on this matter than I do. Also is the pilot jet included in the JD kit, or am I going to have to order it. Thanks! :applause:
