How far out before the fuel scew comes out

Recommended Posts

So I just got an 05 CRF450 and the jetting is off. I have backed out the fuel screw about 6 turns and it is getting better so I know I need to go up on the pilot. But it got me thinking. How many turns until the fuel screw comes out completely.

wouldn't you want to go down? backing it off leans out the mixture, I have never counted how many turns. I know any more than 3-4 out, you should try to go down 1 size pilot jet.

backing out (opening) the fuel screw makes it richer. If it were an air screw, backing it out would make it leaner.
