Hey Guys!
I live in Colorado where the elevation (where i am locally) floats between 5,100 - 5,300ft. I am planning on going to Moab here where the elevation is about 4,000ft. Will I need to rejet before heading down? I just installed a new FMF exhaust and planning on getting the GYTR air filter + adapter when I return. It is running a little lean between about 3/4th - full throttle which makes me think it is my main jet. If i do have to rejet, what size should I get? I was thinking 135 for Colorado and 140 for Moab. Also, if I rejet my main jet, do I have to adjust the Needle or Idle Jet as well? Any help would be greatly appreciated!

Thanks!
Andrew

P.S. the picture below is me jumping my friend's motocross jump. So to say running it hard will be taking it lightly.

You do, I think the pilot controls 3/4 to full throttle but I'm not sure, you may have to move the clip down on position, it's trial and error
