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:

Have you ridden it since the installs/rejet? If you have and didn't notice any problems and a significant power gain, I'd say you're good to go. If you notice top end losses, then it's your needle.
