Mikuni ...a warning!

Decided to clean up my Mikuni VM34 carb today,went to undo the float bowl drain plug and it sheared right off!! F***ing thing now i'm off the road till i can find a replacement.Please everyone who has a Mik on their bike BE VERY CAREFUL when undoing this plug it could happen to you!!! (I think it is made of cheese)

Yes! Had that happen to me years ago and so learned to keep a small amount of anti seise on the threads so that it smoothly screws in and out without galled friction. Did I just say that?
