Tube, primary chain oiler
Primary chain oiler tube from the crankcase, later superseded by 71-1078.
This is the oiler tube that feeds oil into the primary chaincase, listed in the crankcase section of the parts book for 1974. It's a small metal tube that carries a metered supply of engine oil out to the primary chain, keeping the chain lubricated as it runs.

Our records show this part turned up in a single catalog listing for 1974, and it was later superseded by 71-1078 - if you're working from a newer parts book that number is the one you'll find it under. Same physical part, just a later factory number.
We don't have a lot more detail on this one beyond the crankcase figure listing. If you're not sure your bike takes this exact tube versus the later 71-1078, give us a call and we'll sort out which one your engine needs.
