HELP! 05 yamaha wr 450

I have a 05 wr 450f and it dosent want to idle or run right im pretty sure its the fuel screw at the bottom of the carb. problem is i dont know how many turns it should be turned out. and i cant get the bike to idle to attempt to adjust it myself. I have the manual and i cant find where it says it at.

Go two turns out start from their. Do your self a favor and buy a new longer fuel screw soooo much easier to tune.

The R&D adjustable fuel screw would help , cleaning the carb is what it really needs

Clean the pilot jet and bowl has it sat long?
