OKO 30mm Performance CVK Carburetor: GY6 150

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.

Comprehensive Fitment Guide

This carburetor is a high-performance bolt-on for GY6 125cc/150cc 4-Stroke (QMI152/QMJ157) engines found on:

Technical Specifications

• Bore Size: 30mm
• Engine Mount (OD): 36mm
• Air Filter Mount (OD): 46mm
• Installed Main Jet: #126
• Installed Idle Jet: #40 (Extras included: #35, #40)

Tuning Tip: Because this is a 30mm performance unit, it requires more air than a stock 150cc airbox can usually provide. We highly recommend pairing this with a 46mm High-Flow Clip-on Air Filter to realize the full horsepower gains.
