While a Suzuki Boulevard M50 only requires an oil change every 6,000 miles to provide a lot of riding time in between changes, missing even a single oil change can reduce your motorcycle’s service life. If left unchecked for too long, the motor will eventually fail as its oil supply loses its lubricating properties. Changing the oil and filter regularly ensures that your Boulevard M50’s motor runs well for a long time.

Instructions

1) Warm up the motor for up to five minutes. Let the motorcycle idle in place, then turn off the ignition.

2) Lift the motorcycle off its kickstand. Place a wooden block under the kickstand and rest the motorcycle against it to hold the motorcycle in a level position.

3) Unscrew the oil cap from the right crankcase cover.

4) Unscrew the oil drain bolt from the bottom of the motor, using a 17 mm socket and a socket wrench. Drain the motor oil into a drain pan.

5) Screw the oil drain bolt into the motor by hand. Torque the drain bolt to 15 foot-pounds of pressure using a torque wrench.

6) Unscrew the oil filter from the front right-hand side of the motor using a cap wrench. Drain any remaining oil into a drain pan.

7) Coat the new oil filter’s sealing O-ring with 10W40 API SF/SG motor oil. Screw the oil filter onto the motor by hand until it is seated firmly against the crankcase. Torque the oil filter to 14 foot-pounds using a torque wrench.

8) Pour up to 3.5 quarts of 10W40 API SF/SG motor oil into the crankcase through the oil filler on the right side of the motor. Screw the oil cap onto the crankcase.

9) Lift the motorcycle from its kickstand and remove the wood block.

10) Start the motor and check for oil leaks from the oil filter and drain bolt. Tighten the filter or drain bolts as needed if oil leaks occur.
