I am trying to replace the o-ring for my idle mix screw. I can not find any place that sales just the o-ring without the screw. Does anyone know where i can buy just the o-ring or know what the size/measurements the o-ring is so i can try to find one that way?

It is for a 2004 250 ninja. Part number for idle mix screw kit is 16014-1081 if that helps.

Thanks
