Drain bowl screw O ring
The carb' float bowl drain screw in my XT600Z Tenere 1990 appears to be leaking so I decided to replace its rubber o ring.
The parts list that I have for this bike (and also that for a XT600E) do not show an o ring here, so I assumed that it was supplied along with the screw and ordered the screw (5Y1-14115-00), but when it arrived the o ring was missing.
Does anyone know a part number for this o ring?
Should there be an o ring on this screw?
As always, your thoughts appreciated.
