I need to change the oil in my kids quad...no manual. It is a 110cc engine (chinese).

I see several places on the bottom to drain. Which one to I use? Does the entire engine use the oil or does the trans get a different change?

Thanks guys!

 

The engine and tranny use the same oil from the same place. The drain will be the biggest one. It should be the lowest point underneath the gear case near the middle. I don't recall seeing other drains on any of these I have worked on before. Take the oil fill dip stick out first. I always put Honda oil back in. After all, Honda did design this engine nearly 40 yrs ago.
