I have a 07 450x
Ride at sea level to 3000 elavation
Opened up air box already cut side vents and removed snorkel
45 pilot
165 main
2 turns out on fuel srew
3rd position on needle which is a r needle ncvs 16233-men-671
I just added full FMF exhaust with power bomb header and fmf speed titanium muffler.
Noticed it breathing a lot more and seems to need a bit more on rich side as there is a little popping but not much.
Will dropping the clip one notch on the needle get her dialed in ? or turn the fuel screw outmore?
Any advise or wisdom is greatly appriciated.
