OK. Changing the oil.
Let the bike run for a few minutes to get things nice and hot. Burning yourself is part of the process and the hot oil will come out faster. Put the bike on a rear stand. Or the center stand. Or use the side stand if you have nothing else.
You need to remove the right side plastic. Start with all the easy to find aluminum hex bolts. Let's see... I think there's three along the turn signal area, three more along the bottom front, one on the bottom rear, two large bolts in the middle, one under the throttle. Then there is a plastic retainer also under the throttle. Then get the push-pin rivet out of the inner fairing above and behind the front wheel -- near right side of the radiator. Start by pulling the lower back of the plastic up. Pull it loose from the knob near the tank, but be careful that the front section doesn't come loose suddenly and scratch the nearby paint. Carefully work the front loose. And pull towards the rear to avoid scratching the headlight fairing. Bending is OK, but do not force.
Under the engine, between the exhaust pipes is the oil drain plug. Put something that will hold about a gallon of oil under there. Remove the plug. It has standard threads -- left to loosen -- right to tighten. The plug has a magnet built into it. Check it for big metal bits. And loosen the plug above the oil level window -- the add oil plug.
Along the front of the engine is the oil filter. Black cylinder, between the header pipes and the engine case, pointed forward. Once the oil has slowed to a drip from the drain plug, remove the filter. Might need a strap wrench for this. I use a rubber strap wrench from a grocery store used for opening stubborn pickle jars and the like.
Wipe the openings to both the drain plug and oil filter with a clean cloth. Using some clean oil, wet the gasket on the new oil filter and install it. Run it down tight. Reinstall the drain plug. Those are aluminum threads there, so do not strip the threads by getting things too tight. Snug is enough.
Add new oil back into the bike. It takes almost a gallon. 3100mL, I think. Keep an eye on the oil level window when you get more than 3 quarts in. When you have close to the right amount in, close the fill plug and crank the engine. You don't have to start it all the way or let in run more than a few seconds. The oil light will be on. This is normal. It will take a bit for the new oil to work its way through the lines and give a proper pressure. Let the oil settle and check the level. Add as needed. Crank again and let it settle. Check. Add as needed. Like I said before it takes almost a gallon.
There ya go. I think most of this info is right.
