FAQ

Q1: Will this kit fit a Predator 212 or other engines?

A: No, this kit is specifically designed for the Predator 79cc engine’s stock carburetor. It will not fit Predator 212, 224, or other clone engines without modifications.


Q2: Is the air filter reusable?

A: Yes, the included 2.125” air filter is washable and reusable. We recommend cleaning it regularly for best performance and longevity.


Q3: What’s the benefit of using a velocity stack?

A: A velocity stack improves airflow by smoothing and accelerating the air entering the carburetor. This can lead to better throttle response, increased torque, and overall performance—especially on tuned or modified engines.


Q4: Do I need to rejet my carburetor after installing this kit?

A: In most cases, rejetting is recommended when increasing airflow to maintain proper air-fuel ratios. For best results, monitor your engine’s performance or consult a tuning guide.


Q5: Is this kit compatible with mini bikes?

A: Yes! It’s a great upgrade for mini bikes using the Predator 79cc engine, as it provides better breathing and easier filter maintenance.
