The Yamaha 1600 engine, found in the Yamaha Roadstar motorcycle, uses oil to lubricate the cylinder walls like most other engines. As the miles go on, the oil starts to lose viscosity and get dirty. That's why Yamaha recommends changing the oil on a regular basis, which will ensure that the engine lasts as long as possible.
Pull off the seat to the motorcycle with your hands. Locate the dipstick which is on the right side of the seat area, then pull the dipstick away from the motorcycle.
Put the drain pan underneath the middle of the motorcycle. Remove the two drain bolts on the bottom of the motorcycle, one of which is vertically below the factory dipstick, and the other is on the side of the oil tank. Remove these bolts with an open-end wrench and the 3/8-inch ratchet, extension and sockets. Let the oil drain into the pan for 10 to 15 minutes, then reinstall the drain bolts.
Remove the oil filter from the side of the engine using the oil filter wrench. Dip your finger in oil, then run the finger around the rubber seal on the replacement oil filter. Install the replacement oil filter on the engine using your hand, and don't over tighten it or else you will have problems removing it on your next oil change.
Remove the oil fill plug located behind the rear cylinder using a hex-head key. Install a funnel into the plug and then pour 3.2 quarts of oil into the crankcase. Reinstall the oil fill plug.
Reinstall the dipstick and the seat with your hands.
