Service bulletin M1492
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
SERVICE BULLETIN M1492: 2017 - 2019 TOURING - MILWAUKEE EIGHT - INNER PRIMARY VENT. PURPOSE. Revision. Harley-Davidson has learned that a small percentage of dealers and customers are finding low transmission oil levels and high primary oil levels during normal maintenance intervals. This could indicate that oil is transferring from the transmission case to the primary housing through the transmission mainshaft. A inner primary vent service kit (Part No. 26500027) is now available to address this issue. The kit allows the primary to breath and prevents excessive pressure.
