I can't seem to find the wr jetting sticky that I saw a few months ago... I finally broke down and bought a slip on DR.D pipe for my '06...need the extra POWER! ....Question...I did the mods..Air box, grey wire, AIS, and installed a YZ needle. Can I run it this way with the new pipe without damaging the motor? Or do I need to change the main jet and maybe the others? Elevation aprox. 2,000-3,000 ft.. So. cal desert........thanks..
