Rebuilding an 07' YZ250F and I need this bearing. I tried to look it up on the schematic I'm not "positive" which one it is. I think it is number "10" part number 93306-00320-00 but that's the bearing I ordered and it is one of the bigger ones. This is actually a friends bike but I get all the parts for him. He got the bearing out last night and said it is a KOYO 83c107 but I can't find that bearing anywhere. It is the transmission bearing that is in the left side case right where the clutch push arm goes through. If you look through this bearing, right behind it is the "moon shaped" shaft that comes down from where your clutch cable attaches.
A photo would be nice.
You should be able to take the bearing to a bearing supply store to find a replacement.

Of the three ball bearings it is the middle one. The smallest one, second from the left.
Try looking the part up at different oem parts sights to be sure and or call the supplier.
The part number you show matches the output shaft bearing I see in other drawings.
