Breather pipe (metal)
Metal crankcase breather pipe, part number 70-2724 (also E2724), listed for crankcase venting on the engine bottom end.
This is the metal breather pipe listed in the crankcase section, part number 70-2724, also found under the earlier E2724 designation. It shows up across catalog entries running from the mid to late '60s, always tied to the crankcase assembly.

A breather pipe like this vents crankcase pressure out of the engine, letting built-up gases escape instead of pushing past seals and gaskets. It's a simple piece, but a cracked or misrouted one can lead to oil leaks that seem to come from nowhere else.
If you're not sure this matches what's on your bike now, give us a call before ordering. Crankcase breather setups changed over the years and the catalog listing alone doesn't tell us everything about how yours is routed.
