Motorcycle Repair: oil drain on 79 ironhead??

Question
not an expert...where/how do i drain the oil..actually, more a fool....but i cant figure it out...thanks

Answer
If nobody never told you then you shouldn't know, so your not a fool! look at the oil tank and on the bottom of it there is a plug which looks like the head of a bolt. I cant remember on the 79 which side it is on. Your 79 should have some side covers and it should be under one of them
