Instant Throttle Response: OKO 30mm Performance CVK
Eliminate mid-range bogging and transform your scooter’s acceleration with the OKO 30mm High-Performance CVK Carburetor. Unlike standard 24mm or 26mm factory units, this oversized 30mm carburetor features a built-in accelerator pump that delivers an immediate squirt of fuel when you crack the throttle, ensuring crisp, bog-free power delivery from a standstill.
Technical Performance Features
- Integrated Accelerator Pump: Solves the common "flat spot" in GY6 acceleration by providing supplemental fuel during rapid throttle transitions.
- 30mm Oversized Bore: Increases airflow capacity, making it the perfect match for 150cc engines equipped with big-bore kits (170cc–180cc).
- CVK Constant Velocity Design: Maintains optimal air-to-fuel ratios across varying altitudes and temperatures, offering smoother rideability than manual slide carburetors.
- Tunable Jetting: Comes pre-configured for 150cc engines but includes additional pilot jets (#35, #40) to help you dial in your specific exhaust and intake setup.
