There is an oil pump.
And if you bought a quad that is under 2006, you might want to look in to doing an oil mod. Or checking out the J&T racing, sponsor section on this web-site, they bore your case cover put in a squirter and a high velocity pump, that comes standart after 06. Prevents your bike from blowing up in... j/k.
Acording to the manual you put 0.33 in the crank case. And 1.55 in the oil reservoir. It's ok if you do a little more.
