Hi, I am new to Honda bikes. A friend's roomate left this engine in friend's house when he moved out. Anyway that friend was going to just junk it. I figured I could find some use for it. Problem is idk what it is.

I could only find 2 numbers on it

Any information is useful. Size, year, type

 

Without full engine numbers, pictures, or anything to go on. This question can't be answered.
