We decided to make a Full Billet CNC Billet Velocity stack for the OKO 28mm & 30mm. Our Velocity stack is matched smooth to the inlet throat of the carb. Adding this will require more fuel and we highly recommend tuning with a PWK Main Jet Kit.
2.25″ Tall, 2.5′ Front OD 1.80″ ID , Flange 1.96″ ID
These are recommended for Racing or High MPH runs. Check out out Billet Carb Tops too. Comes with set screws.
