Kuryakyn Bluegrass Breather Kit for Harley-Davidson CV & Delphi Carburetors

Combat messy crankcase blow-by with the Kuryakyn Bluegrass Breather Kit, designed for a wide range of Harley-Davidson motorcycles. This kit is compatible with engines featuring CV Carburetors from 1993-2006 and Delphi fuel injection systems from 2001-2017 (excluding 2008-2017 Touring models). It effectively addresses the common issue of oil being expelled through cylinder head vents, preventing it from soiling your air cleaner and the side of your motorcycle.

Engineered for Clean Performance:

  • Broad Fitment: Covers Harley-Davidson models with CV Carburetors (1993-2006) and Delphi EFI (2001-2017, non-Touring).
  • Prevents Oil Mess: Reroutes crankcase vapors and expelled oil droplets upwards, keeping them within the engine.
  • Protects Air Cleaner: Stops oil from contaminating your air filter and intake system.
  • Improved Aesthetics: Maintains a cleaner appearance for your motorcycle by preventing oil drips and messes.
  • Quality Construction: Features durable banjo fittings and chrome tubes for reliable performance.
  • Easy Installation: Designed for straightforward integration with your existing engine components.

The Bluegrass Breather Kit utilizes gravity to ensure that any oil expelled from the crankcase returns to the engine, rather than coating your air cleaner or engine components. This not only keeps your bike cleaner but also contributes to better engine health by managing internal pressures and vapors effectively. For those who prefer venting to open air, the kit facilitates running the vent line discreetly. An optional catch tank is available for users who wish to vent into a closed container.

Ensure your Harley-Davidson breathes easy and stays clean. Equip your ride with the Kuryakyn Bluegrass Breather Kit from GGCRACING.
