Harley V-Twin Oil Catch Can

Oil catch can for Harley Sportster, Dyna, Softail and Touring

Crankcase vapor separator for a clean intake and stable idle

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

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

Whether you ride stock or with a stage 1, this oil catch can prevents fouling of throttle plates and the air filter, reducing oil consumption through vapors and spray. Result: a healthier engine, simplified maintenance and consistent performance over the miles.

Why upgrade the stock part?

In many stock configurations, oil vapors from the crankcase are routed into the intake. Over time this causes oily deposits, disrupts airflow and can lead to an unstable idle or hiccups at low rpm. On bikes ridden daily or over long distances, this phenomenon increases with heat and aging.

• Greasy deposits in the air filter housing

• Throttle plate fouling and idle fluctuations

• Increased oil consumption through vapors

• Unsightly drips and spray on the right side

This oil catch can intercepts vapors, condenses and retains oil before it reaches the intake. You keep a clean airflow, a smoother response and lighter maintenance, while keeping an instant eye on the collected level thanks to the transparent body.

Ideal use:

• Owners of Harley-Davidson Sportster, Dyna, Softail and Touring seeking a cleaner intake

• Bobber, café racer, tracker or minimalist custom builds

• Stage 1 machines with performance air filters to limit fouling

• Urban rides and traffic jams where vapors accumulate more

• Long-distance riders seeking constant reliability and simplified maintenance
