Blue Line GY6 125/150cc Intake Manifold Gasket

Eliminate Air Leaks: GY6 125/150cc Intake Gasket

Ensure a perfect, airtight seal between your engine and fuel system with the Scooterworks GY6 Carburetor Insulator Gasket. Designed for the ubiquitous 125cc, 150cc, and 169cc GY6 (QMI/QMJ) engine platforms, this gasket is a critical component for maintaining a steady idle and optimal air-fuel ratios. Whether you are installing a new performance intake or performing a routine top-end rebuild, using fresh gaskets prevents the "lean-run" conditions that can lead to engine overheating and poor throttle response.

Technical Performance Features

• Precision 45mm Bolt Spacing: Engineered to match the standard 2-bolt mounting pattern found on GY6 150cc intake manifolds and cylinder heads.
• Heat-Resistant Composite: Manufactured from high-grade gasket material designed to withstand the high operating temperatures of air-cooled engines without shrinking or becoming brittle.
• Vibration Dampening: Helps isolate the carburetor from engine harmonics, reducing fuel "foaming" in the float bowl for more consistent power delivery.
• Universal Engine Compatibility: Fits a massive range of "QM" and "FM" series engines found in TaoTao, Wolf, Bintelli, and Genuine scooters.

Comprehensive Fitment Guide

This gasket is a direct replacement for 152QMI, 157QMJ, and 161QMK engines. Common model applications include:

Technical Specifications

• Inner Diameter: 22mm
• Bolt Hole Spacing: 45mm (Center-to-Center)
• Material: Reinforced Gasket Paper/Composite
• Quantity Recommended: 2 (One for each side of the plastic insulator)

Mechanic's Note: Most GY6 intake setups require two of these gaskets—one sits between the cylinder head and the plastic insulator spacer, and the other sits between the spacer and the intake manifold. If your scooter is "hanging" at high RPMs after you let off the gas, you likely have an air leak at this junction. Always scrape off old gasket residue completely before installing these new ones to ensure a leak-free seal.
