Okay I ride at sea level to 3000 feet.
Just want to open airbox up and keep stock exhaust.
What size main and slow jet?
Size needle and clip position?
Air srew adjustment?
Is it possible to get just the needle and 2 jets from my dealer to save some dough?
Other than that this is my first 4 stroke after riding a 2 smoke and I am lovin it.

165 main jet
stock 45 pilot is fine
NCVS needle 3rd Pos. Part # NCVS 16233-MEN-671 its an option needle out of an 04R You can get it from your dealer.
Fuel screw out 2 turns
You will also want to open up your airbox. At a minimum cut the whole top off.
The smog pump will also need blocked off. Being your from Cali. I would do the JB weld
If you need pics of anything let me know. I probably have it.
Welcome to the site, there are a bunch of good guys in the 450X forum. Lots of info and people to ride with from Ca. What part of Cali are you from.

I'm gonna put together a jetting kit and market it myself.
It's gonna be called the JDF2 kit and it's gonna retail for $ 300.00.
It'll be 3 times better than the JD and twice as good as the F2.
