Doesnt really matter the order u drain the oil...she should take around 3.5 quarts, and u put oil in the tank. As far as checking the oil pump, thats a tough one. First off is there something that make you think theres a problem? The oil light should come one when u first turn the key, if that is happening u should be OK. Beyond that you can install a oil pressure gauge. Ive also heard of people removing the tappet caps on the valve cover while the bike is running, and look for oil.
