Was up all. Kinda new with this, can anyone help me out. I have a 2007 yfz450 and just put on a Dasa full exhaust, air box lid is on, rejeted w/ 172 and a 45. Is there any other adj. that I need to do? Someone told me that the needle is not adj. on the 06-07 does this sound right. Thanks for the help. :icon_biggrin:
