right only. 650-700ml, lean the bike and pick up the front tire to drain the oil out the head.

so you pull both plugs and let the oil drain then put it them back in and refill? I thought u just pull the one were the skid plate isnt blocking?

i'll have to try that next time, how much oil is usually in there? will it hurt if you dont drain it?

I think the plug on the left side you are referring to is the cam chain tensioner plug. You DO NOT want to pull that one out to drain the oil.

Drain the oil from the larger plug on the bottom. As far as raising the bike up to empty the head :) I will have to try that one!

That's correct. I just did my son's crf 50 a few days ago. It's the larger of the two plugs. I think its a 1/2 inch socket. When you fill with oil, stop once in a while and check the level with the little dip stick, so you know its not over filled. :)

17mm, no standard bolts on the 50 :)

i try to do a complete drain on my bike, get as much dirty oil out as possible. 650ml will be center of the dipstick if you do it this way and 700 will be up to the top of the xhatch. to get an accurate measurement start the bike after you change the oil, idle for 30 seconds, shutoff and check the level again.
