xr70 lost its drain plug

i took my son for a ride in the riverbed by our house yesterday afternoon. All of a sudden his bike dies and wont stay running. I thought he was low on gas but a buddy notices something pouring out of the bottom. He had lost his drain plug. I retraced our trail following the oil stains and actually found the plug. It was about 1/4 mile back. i had my wife bring the truck over and got it home but i am scepticle about just putting oil in it and seeing if its fine. i know these little bikes are prettty much indestructable but im a little scared. At the same time I dont want to tear it all apart if i dont have to. Any words of wisdom outthere?

if it's toast it's toast  putting oil in it and trying again won't do any further damage IMHO

 

I'd give it a go  assuming it will turn over ?

 

  otherwise you are ripping it apart and inspecting all the bearings

True. I have to rebuild maybe this would be a good time for a big bore kit
