So I want to change the oil in my MC28. However I have found 2 different spec's on oil amount. can someone please tell me which one is right thanks.

This link says .7l http://nsr-world.com/specs/nsr250/mc28/

and

This link says 1.2l http://www.nsr250.net/history_mc28.html

Also is it correct to add the oil while the bike is upright and not on the side stand???

Thanks guys
