Bulletin Summary
SERVICE BULLETIN M1450: MILWAUKEE-EIGHT EQUIPPED VEHICLES - LOSS OF POWER OR HIGH ENGINE BRAKING. REVISION. Purpose: 2017 - 2019 model motorcycles equipped with a Milwaukee-Eight? engine can experience a condition known as sumping during extended periods at high rpm or under heavy engine load. Sumping is when an excessive amount of oil is suspended in the engine crankcase and the flywheel must travel through the oil, resulting in loss of power or a high degree of engine braking and potential engine component damage with extended use under these conditions. This bulletin provides the diagnostic procedure for determining if sumping is occurring.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
