Raptor air/fuel mixture screws
Does anyone know what the stock setting for the air/fuel mixture screws on an 05 Raptor 660? I need to know how many turns out they should be from bottomed.
Also, Does anyone here run a Yoshimura pipe? If so, did you have to change your air/fuel mixture settings.
Thanks.

If your dealer set the bike up for you then they should have tweaked the a/f screws for your temp and elevation. But most dealers dont do this to my knowledge.
The stock settings are supposed to be 2/2.5 turns out. Depending on your bike setup and environment along with what jetting and pilots you install it will affect the necessary screw settings.

now when you guys say 2 1/2 turns out on the fuel screw on stock setup.... is that two full 360 degree turns followed by one 180 degree turn? or two 180 degree turns followed by one 60 degree turn?
Someone please respond ASAP i need to get my raptor going ASAP.
what happend was i went for about a 30 minute drive and it ran great just after about 20 minutes of riding up and down hills over and over i was on a hill for about 20 minutes just riding on it and it started to idle really low almost like it wanted to shut down i revved it and it started to back fire and when i got home it got worse so im thinking the elevation screw up the fuel srew or something, any suggestions?
