Can't find the drain bolt.

I have a 1983 cr250 and I can't figure out if or where the drain bolt is. I would imagine it has one since all motors should have them. But my question is where. I have to drain my oil. And mess with the clutch so it will disengage And I can shift. I don't want to do what I did last time and contaminate my brand new oil. I want to take it out in a clean way so if it checks out I can reuse it. Please help. I want to get this done asap so I can finish up my project and get ready to paint and clean up the bike.

lower right hand side..pretty large hex head bolt with magnetic tip.
if you are just working on the clutch you can lay the bike on its right side also if the tank isnt too full.
look up the clutch adjustment procedure on here, among other things

don't undo the gear lever of kick start lever, they stay in the clutch case. just undo the screws and gently pop the cover off being carefull to avoid breaking the gasket. try to keep it on the engine or the cover.

Ok thanks guys I know the how to ajudst it. I just needed to drain it. I have had in it.
