GY6 CVK Carburetor - 125cc (QMI152) /150cc (QMJ157)

This GY6 carburetor is a direct replacement for any 125cc or 150cc GY6 engine and comes ready to run straight out of the box. It’s jetted for sea-level conditions, so if you’re riding at normal elevations with a stock intake and exhaust, you’ll be good to go.

If you’re planning on adding a pod filter, installing a performance exhaust, or doing any kind of airflow upgrade, it’s a great idea to grab a few jets or additional tuning parts with your order. We carry everything you need — pod filters, jet kits, exhausts, you name it.
