If your fuel mixture screws were $10, then they are not vitos. If they're not vitos, I'd be very suspicious of them. You may have to do a lot of messing with them to get it right Regardless, try this. On your left fuel screw, screw it all the way in till it bottoms out, then back it out like 1/8 turn or less. Back out your right fuel screw about 2 or 2.5 turns. These adjustments should be tested when your machine is 100% warmed up by riding for at least 5 to 10 minutes, not just idling in the driveway. This was the only way my 660 would run and not be overly rich.
I have a 03 raptor 660 and it won’t rev at all changed the carb cut the green/yellow wire grounded the green/white and it revs up by itself and nothing has worked for me gone there every fórum and tried everything they say

I’ll try that thank you, These mixture screws are exactly the same in dimension to the oem ones because I measured them using a mic

Are your fuel mixture screws correct? Both should be at 2 turns out
Idk if the valve adjustment could fix my problem
What's your problem now?
I fixed all the issues on my raptor
