i just bought a 2000 suzuki quad runner 4wd how and where do you check the oil and also the owner gave me a document entitled title of origin is this the title that i need to change over to my name or something else?

 

Welcome to the forums.
The title of origin is what you get when you buy a new machine. This machine was never titled with the state.
If you go to get a title, don't be suprised if they want you to pay tax.

I'm sure someone else will chime in and help with the other questions.

 

On most 4wheelers, you check and fill on the right side. Either there is a sight glass by the bottom or tjere is a dipstick on the oil fill lid on the case cover

 

If it's a King Quad 300 or a Quadrunner 250 then there is a sight glass, not a dipstick. Look just in front of the right rear axle behind the tire. What you are looking for is a round sight glass about the size of a nickel. Once you find it and clean it off you should see the oil level through the glass.
