GY6 125-200cc You-All 26mm CVK Performance Carburetor

You-All 26mm CVK Performance Carburetor for GY6 Engines

This 26mm CVK carburetor from You-All is built to increase airflow on GY6 engines in the 125cc, 150cc, and 169cc range. It suits riders looking to get more out of their engine. It is one of the GY6 150cc scooter parts that can make a noticeable difference in efficiency, particularly when paired with an upgraded cylinder kit or exhaust. The electric choke helps with dependable cold starts, so it works well across different riding conditions.

Airflow and Tuning Potential

The carburetor uses a 26mm slide bore, which allows more air through than a typical 24mm unit. That extra flow can translate into quicker throttle response and better overall performance. Out of the box it comes set up with a #105 main jet and a #35 idle jet, giving you a starting point for tuning. An adjustable enrichment screw lets you fine-tune the mixture to your preference.

Cold-Start Assistance

The electric choke on this You-All carburetor handles cold-start enrichment for you. It helps the engine fire up smoothly when temperatures are low, making everyday starts simpler. A included fuel filter helps keep fuel flowing cleanly, which supports consistent engine performance.
