Changing engine oil in motorcycle

Put your drain pan under the bolt.
Use the proper drive ratchet/socket ratchet or Allen key to remove the drain plug bolt.
Remove the engine oil drain plug.
Undo and remove the oil filler plug, this allow air to enter the engine the engine more easily as the oil drains and so the oil will drain more quickly.
Leave the drain plug /oil filter out for some time, it’s surprising how long oil will continue to drip for, you put your side stand for a while which helps oil drain from ‘nooks and crannies’ within the engine.
Remove the old oil filter unscrew a few turns until oil starts to leak, leave a few moments before unscrewing a little further allowing more oil to escape, now unscrew and remove completely.
Clean and then reinstall the oil drain plug having fitted a new crush-washer.
You can get away with reusing the crush washer but for the sake of few money you’re better off buying a new one when you get your new oil filter.
Clean the underside the sump, wipe oil from where the oil filter locates and then install the new oil filter.
Pour your new engine oil slowly according to engine oil capacity, see owner manual to find capacity.
The oil level should show about midway in the oil level sight glass.
Replace the oil filler cap properly make sure the O-ring, is in place.
To check the oil level properly, start the engine and let it idle for a while and off now wait at least five minute and recheck it again.

In order to ensure that the oil level is read correctly, check the oil level only after a lengthy trip.
Dispose of used oil in an environmentally friendly manner.
