GY6 PWK Complete Performance Carburetor - QMJ157

The Details ⚙️

Want faster throttle response and real performance gains? This PWK flat slide carburetor kit is one of the best upgrades you can make to your GY6 QMJ157 setup — period.

This is a complete, pre-assembled drop-in kit that includes everything you need: PWK carb (size + finish of your choice), intake manifold, Uni pod filter, throttle cable, and full jet kit. No piecing things together — just install and tune.

We ship each carb with a base tune for sea level, but expect to fine-tune depending on your elevation, engine size, and setup. If you want to dial it in perfectly, a wideband is highly recommended.

📊 Take the guesswork out of tuning: Wideband O2 Sensor Kit

Choose your setup based on your build:

• 26mm — Best for 150cc
• 28mm — Best for 170cc–180cc
• 30mm — Best for 190cc–232cc

More airflow, quicker response, and noticeably stronger acceleration — this is a must-have upgrade 🔥
