How do you change oil in a 2002 650 Savage?

First of all, do NOT buy and oil filter from Walmart. They will give you the wrong one and they don't have the correct one in stock. The Savage does not have a screw on oil filter. Go to a motorcycle dealership to get a filter. Buy 10w-40 oil. Get at least 3 quarts. Car or motorcycle oil: either on works fine. You fist need to drain the old oil. There is a 17mm plug on the left side of the very bottom of the motor. Once it's drained, use an Allen wrench to take off the oil filter guard. It's the triangular shaped thing toward the front on the right side of the engine. Oil will leak out when you take it off so you may want to move your oil pan to underneath of it. Take out the old filter and replace it with the new one. Put the guard back on and the oil plug back in. Add in your new oil at the top of the engine on the right side. Add about a quart and a half to start and then check it in the oil level window (right side at the very bottom). Keep adding a little at a time until it is at the correct level. Once the oil is at the right level start the bike and let it run for a minute or two. Turn the bike off and check the level again. Add oil accordingly. Hope this helped.
