Oil drain plug dimension

Hi

ANyone knows the oil drain plug dimension?

Need to buy a gasket for it, and I don't want to unscrew it and let the oil out.

Cheers

it would be most helpful to know what bike youd want this for???

Sorry, thought it showed under the profile image....

It's a kz650 B2 -78.

Don't know the size but if it's not leaking bad just go ahead and run it till your next oil change. Then take it off and find a gasket for it. I believe factory gasket was metal.

The drain plug bolt is very close to 12 mm (more like 11.75 mm), the diameter of the bolt head is 20 mm. A 12 mm (inner diameter) bronze or copper washer should do the trick.

Perfect! Thanks!

I have recently changed the oil, but didn't change the gasket. Now I think that it would be better to have used a gasket, instead of tighten the bolt a bit hard. So I thought of retighten the bolt a bit softer this time, but with a coppar och bronze gasket to seal it.
