G'day.
There is no oil filter in a two stroke. Your bike has two types of oil for the engine.

In the gearbox, it uses a light viscosity 2 stroke motorcycle gearbox oil.

Then you have the oil that you pre-mix with your fuel(to lubricate the top-end & crankshaft bearings).

Oil for your bike is best purchased from a motorcycle shop- this is a racing bike that requires race type maintainance.
The better the maintainance the longer it will last.
Things like,
Keep the chain lubricated.
Keep the air filter clean & oiled correctly with propper air filter oil(this is REALLY important).
Use high octaine fuel-(if in Australia like me-no ethanol fuel- 98 octaine).
Use the best quality 2 stroke oil you can afford-preferably full-synthetic.
Here is a link to parts fishes(exploded diagrams) for your bike.
These will help you see all the parts & gives a good idea on what goes where.Click on the part name & it will show you a picture. : )

If you have any other questions don't hesitate to ask.
Kind regards Andrew Porrelli

What other year cylinder head will fit a honda cr 2003 125


I searched for this and found that no other machine has this cylinder head, and that it appears as though there were 2 versions of the same head made for that year. My link below is for Bikebandit. I did a couple of searches for other machines that may fit this and found none. Good luck on fixing your bike.

Oil change on a 2003 yz250f.


the oil in the frame is pumped into the crankcase, i had the same problem so i asked at the yamaha dealers. the dipstick on the frame is for checking the oil and the plug on the crankcase is for filling it with oil. I believe it takes about 1liter of oil from other posts but i could be mistaken
