Use 600 ml is you are changing the oil, or 650ml  if you have just rebuilt the engine and filling from dry. Use light weight gear oil.

What is the proper ratio to mix of the oil to gas?

There is a big range of answers to that question but to give you some idea of the answer 32 parts petrol to 1 part oil - right up to 60 parts petrol to 1 part oil is the range of ratio that most commonly would be used . to give some insight in simple terms the more fuel and less oil mixture you will burn hotter and produce more power but sacrifice wear and tare on the motor
realistically the mix you choose depends on what sort of riding you intend to do - if you are racing and want the hole shot then 50 - 60:1 mix with half pump fuel and half race fuel will get you there but you will be rebuilding the top end fairly regularly
For recreational use only then 40:1 mix with standard pump fuel only would be the most common as it is in the middle of the range giving you good power with high level lubrication so ware and tare kept to minimum.
if you make changes to fuel mix then keep the changes small just alter the mix slightly and record the results because you will also find each bike responds a little differently
when I am setting bikes up for events I usually will go out to test area with 3 or 4 bottles each just with 500 ml of different mixtures in them and give each mix a test just for five or ten minutes then once the best mix chosen the I start fine tuning the carbi fuel air mix etc only takes an hour or so and what the hell it's a lot of fun to do any way!
