Purevenom, you lift the bike by the frame, under the engine area. Roll the jack to the exhaust side of the bike. roll the jack forward until it touches the underside of the engine area, making sure that the jack pads are under the flat sections of the bike frame. Grab the handle bar and pull the bike to an upright position. While holding the bie upright, slide the jack underneath the the frame. make sure you leave about 1 1/2" of pad showing (it sould be approx. the same on the left side). Start raising the jack, and the bike will settle onto the pads. Once there, lift until you have it at the desired height. (note: the bike will rock alittle backwards due to the weight balance being a little rearwards.)
This is my method. some have different ones. Hope that this helps.
