Harley V-Twin oil catcher

Oil catcher for Harley Sportster, Dyna, Softail and Touring

Crankcase vapor separator for clean intake and stable idling

Optimize the breathing of your American twin with this oil collector / vapor separator designed for Harley models with vented crankcase. By isolating the oil contained in the crankcase vapors, it prevents deposits in the intake, improves idling consistency and helps extend engine life.

Thanks to his transparent anti-shock body, you can check the collected oil level at a glance and know exactly when to change. Its compact format and universal mounting allow clean installation on Sportster, Dyna, Softail and Touring, whether on a café racer, bobber or daily rider.

Whether you are driving in the original configuration or with a stage 1, this oil collector prevents clogging of the throttle valves and the air filter, reducing oil consumption by vapors and projections. Result: healthier mechanics, easier maintenance and consistent performance over the miles.

Why improve the original part?

On many original configurations, oil vapors from the crankcase are returned to the intake. Over time, this causes oily deposits, disrupts airflow, and can result in unstable idling or jerking at low revs. On Harleys used daily or over long distances, this phenomenon increases with temperature and aging.

• Fatty deposits in the air filter housing

• Throttle fouling and idle fluctuations

• Increased oil consumption by vapors

• Unsightly discharge and spatter on the right side

This oil catcher intercepts vapors, condenses and traps oil before it reaches the intake. You thus maintain a clean air flow, a more regular response and reduced maintenance, while keeping an instant eye on the level collected thanks to the transparent body.

Ideal use:

• Harley-Davidson Sportster, Dyna, Softail and Touring owners wanting a cleaner intake

• Bobber, café racer, tracker or minimalist custom preparations

• Machines in stage 1 with performance air filter to limit clogging

• Urban journeys and traffic jams where vapors accumulate more

• Long-distance drivers looking for consistent reliability and simplified maintenance
