I have a yamaha roadstar 1700 need to know how many qaurt of oil it take & if it has two drain plugs If so were are they located

Your bike takes a little over 4qts of oil. The engine drain plug is located on the lower left front of the motor. The oil tank drain plug is located on the bottom of the oil tank, on the right side of the bike.
When refilling, put in about 2.5 quarts of oil in the tank and start the bike and run it for about minute and blip the throttle a few times. Then add the remainder of the oil. Run the bike to operating temperature (approximately 15 min) and allow it to idle for about 3 minutes. Then check the level after a minute or so and adjust as necessary.
