I do mine a little differently, I put 1.7L in the oil tank & the remainder measured oil I poor down the engine breather hose, go for a short ride then adjust oil level to suit the dip stick. This way you will never over or under full the motor & won't have any spills.
I perfer my way then what Yamaha states to do, my way you have the tank full & the correct amount of oil in the motor at start up.
