So, I decided since the CBR250R is a bike aimed at beginners, a lot of new riders might want to know how to change their oil. I decided I'd supplement available information with a picture DIY.
It's really not too hard, takes only about 30 minutes to complete.
The only tools needed are:
5mm hex wrench
Torque wrench(some people don't use one, but I have one, so I use it. I'd rather not strip the oil drain bolt)
Along with this pick up a new oil filter, oil gasket, and crush washer. Costs less than $10.
You will also need new oil and a small funnel.
I am using Shell Rotella T5 10W-30 semi-synthetic motor oil.
Now onto the oil change....
Warm up the bike by riding it so that the oil flows out quickly.
Remove the oil filler cap, located on the right of the bike.
Locate the engine oil drain bolt and loosen it. It is a 12mm bolt. Quickly remove it so that you don't get oil all over yourself.
While that is draining out, remove the right lower fairing bolt. It is a 5mm hex bolt. Behind it is the oil filter.
I didn't remove the middle fairing. I just pried back the right lower fairing. It doesn't give you too much room, but it is enough to sneak out the filter.
Remove the four 8mm bolts of the oil filter housing, which is the circular object the arrow is pointing towards. The four bolts are circled.
The oil filter housing should come out now, with quite a bit of oil. It is somewhat messy, try to get your oil drain pan underneath the filter housing. It will drip over the exhaust as well if it is on the side stand.
Underneath the filter, which is the large object in the middle of the housing is a spring. Make sure you don't let that escape.
This is the new filter. Note the OUTSIDE
written on it. That part needs to be mounted facing outwards.
Hold back the fairing and put the new filter with OUTSIDE
facing outwards as pictured below.
Now, with the new gasket in place, re-insert the oil filter housing, making sure the spring is in the same place. It may take a third hand(helper) to hold the fairing back and get a bolt in so that it stays in place. I believe the torque value for the oil filter housing bolts is 9 ft/lbs. I just hand tightened them, plus a little more and it does not seem to be leaking.
Next, with your new crush washer, put some engine oil on the drain bolt threads and hand tighten it back into place. Then with your torque wrench at 18 ft/lbs tighten the oil drain bolt down.
Now with your new oil and funnel, fill up the oil so that it reads between the upper and lower levels in the oil sight window on the right side of the bike. Do this with the bike level. Now close up the oil filler cap. Start the bike up so that oil can circulate through it. Then turn it off and leave it for a few minutes while you clean up. Check it while level again and pour in more oil so that the level is correct. Make sure you replace the oil filler cap.
Notice the upper and lower marks.
Congratulations! Your oil change is complete. Ride and enjoy
