Hello everyone! I'm a new rider and just got my first bike to learn on. Its a 2006 KLX 125 4 stroke. I want to change the oil and got everything ready. However I can't figure out which plug is the oil plug because there is 2 bolts on the bottom of the motor. I'v tried googling and nothing seems to tell me which is which. Anyone out there have any idea? Thank you!
1 or 2? for Oil drain?

 

Figured it out. Bolt number 2.
