650mL for replacing and 700mL from a bottom end rebuild(so fully empty)
and i use bel-ray gear saver(forget exact type but its like 80W90 or something) most people use 10W30 but the one i use lasts longer and just more protection.
it is .75 quarts or 650 cc's or 650 ml of oil. i also use the golden spectro and works great. i think yamalube and yamaha oils are overpriced, and maybe overrated.
