Default Raptor Air/Fuel screew.

hey all. I have a Low end bog, like when i first nail the quad, it bogs, then gets all its power. Im guessing its the air/fuel screew because everything is stock and its pretty cold out ( 10degrees). Does anyone know how many turns out stock the screew is? thanks all. oh yea, im guessing its from a lean screew, not a rich, i think. any help is great, thanks.

i just finished jetting my blaster and i retuned it and it was doin the same thing so i leaned it out a lil bit.... 1/2 a turn. key thing- REMEMBER WHERE YOU START FROM! dont just play with it and hten have no idea where you started from. run it in untill it bottoms out and count how many turns it is. that way you have a starting point to start form. hope that helps

I believe after bottoming the the screw out...3 full turns will take it back to the stock setting. Thats where mine was after purchasing it from the dealership. I live below 1000 ft. for sea level by the way. Good Luck

I'm at about 500ft and mine came around 2/2.5 turns out (left/right) from the dealer. Temps are similar. Remember that 3 turns on the screws is equal to one size up on the pilot. I think they stock carbs got 3.5 or 4 turns.
