Socket size for 98 Katana600 oil drain plug?

[artlovingbiker]

Hello there!

I am trying to do oil change on my 98 Katana 600 for the first time and I am wondering what size socket I need to have for drain plug!
I just noticed that the drain plug bolt is bigger than other newer bikes plugs!

Please help!

Cheers...

If I'm not horribly mistaken, 13/16s or 18-19mm. Changed my oil bout 3 weeks ago and pretty sure it was 13/16s

For my 93-750 I use a 13/16 socket and it fits tight. That would correspond to a 21mm socket.
The on-board tool kit comes with a 22mm flat wrench but it fits too loose, and no way you can use that between the pipes.
