How To Change Motorcycle Engien Oil

Clean your work area
Before you start, make sure the oil-change area is clean and free of dirt and other contaminants.

Access the drain plug and oil filter
Remove any parts that restrict access to the filler plug, drain plug and oil filter. 
Note: some bikes may require removing foot pegs or fairings Removing fairings may be necessary to access the oil fliter, fill and drain plugs.

Drain the oil
Place the drain pan under the drain plug to catch the used oil. Identify the fill and drain plugs at the top and bottom of the engine case. 
Remove the oil-fill plug first, then remove the drain plug with a socket wrench. Let the old oil drain 5-10 minutes until the stream has reduced to a trickle.

Remove the oil filter
While the old oil is draining, remove the old filter. You may be able to unscrew the filter by hand, but an oil filter wrench makes it easy.
The tools and procedure required for removal of cartridge-type oil filters may vary; refer to your owner’s manual. 
Use a clean rag to wipe the area where the oil-filter gasket contacts the engine.

Install a new oil filter 
Use your finger to spread some new oil on the filter gasket to lubricate and create a good seal. 
For spin-on oil filters, screw the new oil filter clockwise until snug, but still removable by hand. If using a filter wrench, turn the filter a quarter-turn after it is hand-snug to secure it.
For cartridge-type oil filters, tools may be necessary to reinstall the oil-filter cover.

Reinstall the drain plug
Replace the drain plug gasket with a new one if your drain plug has one. Screw the drain plug in by hand until snug, to reduce the risk of cross-threading. If you encounter any resistance, back it out and try again. Finish tightening with a torque wrench set to the manufacturer’s torque specifications. 
If you do not have a torque wrench, tighten the drain plug only 1/4-turn from hand-snug with a box or socket wrench.
DO NOT overtighten.

Add new motorcycle oil
Refer to your owner’s manual to verify how much oil is required. Depending on the bike there will be a sight glass on the engine or a dipstick to determine fill level. 
Using a funnel, add 3/4 of the recommended amount of oil. Check the oil level, making sure the bike is level.
Continue adding oil until the level is between “Low” and “Full.” Reinstall the oil-fill plug.

Run the engine and check for leaks
Double-check the oil level.
Add or remove oil if necessary.

Properly dispose of the used oil and filter
It’s often easiest to return the used oil from your drain pan into your new oil containers after you’ve filled your bike.
Be sure to dispose of your used oil and filter properly and in accordance with government regulations. 
Most municipalities, auto parts stores and oil change facilities accept used oil at no charge and recycle it, to keep it from polluting our waterways.
