alright my raptor is goin beserk i start it n it runs but i hit gas n it stalls so i messed with the idle screw n it didnt do it that much ut it was backfiring like no other. also What is the stock idle screw normally at?

 

basically i need idling 101

 

alright i juss figured out that in is higher and out is lower so now my idle is ok and when i took off my airbox it ran perfectly. do you guys think it was runnin rich or.........

 

most likely rich but could have been a clogged jet that freed up after a while

 

now its running right except it feels slugish on my topend power

 

find out what size jets you are supposed to be running for your elevation and temp.
and is it completely stock right now other than your lid off,
you should also check your carb to make sure nuthin is blocking airflow

 

it is bone stock, i am goin 2 open her up n check them carbs out 2morrow
