how many turns out of the air screws is the stock setting for a 2002 raptor

 

That will depend on elevation for the exact setting your engine will like. Start at 1 1/2 to 2 turns out, warm it up, run it up to speed in 3rd gear, then let it coast,don't pull in the clutch. If it pops or sputters through the exhaust, turn them out 1/4 turn at a time until it coasts without back pops from the pipe.

 

Both of mine was set at 2 1/4 turns out, I'm at 675' elevation.
I'm sure your higher than that in Tenn.

 

Thanks MOOSE, that should give me a place to start

 

Moose is correct. 2 1/4. Stock is lean. About 3 turns out is right.

 

ok i set my air screws 3 turns out, it got rid of the bottom end bog and backfire , but my pipes still have slight red glow to them, all other jeting is stock (pilots, 22.5, Mains 140,145)the only thing i have done to the bike is a pro-flow intake
most of th riding i have been doing is in a fild second and third gear, with varied throttle, my dad is in need of the computer right now so give me any suggestions u have and ask any questions u need anwered

 

Go with a Dynojet kit & follow their recomendations for your mods & altitude.
You'll also have all the jets you need for future add ons.
Like Murph said they're jetted on the lean side from the factory, for emmissions I guess.

 

ok thanks MOOSE i was thinking jet kit any way

 

I would consider getting the GYTR jet kit. [img]i/expressions/face-icon-small-cool.gif[/img]

 

Most dealers I called said stock fuel screw settings are 3 turns each & that the left screw should be left alone, just turn the right one in/out to accomodate. I turn both myself. I have found 3 turns each works good for the hot weather & 3 1/4 turns each works good in the cold weather. The only way to really know is to experiment.
