Missing carb screw, 97 yz250

Does anyone have the part number for the idle(pilot) screw on the left side of the mikuni carb?  It worked itself out on the trail and I lost it.

May be 4SR-14105-00-00.

 

I don't know it for some reason, I couldn't find 97 YZ250 at the online parts cataloge of Yamaha motor U.S.A. http://www.yamahamotorsports.com/partviewer/default.aspx?ls=sport

But, "PILOT SCREW SET" of 96&98 YZ250 were shown as the same parts number  4SR-14105-00-00.  97 screw must be the same.

And I confirmed 97 YZ250 at the online parts cataloge of Yamaha motor Japan.The same parts number was shown. Confirm whether it is the screw what you intended or not.

That's it. Thanks.

That's it. Thanks.
