Clearance for Power: Shin Yea Cygnus-Style Intake Spacer

Unlock the space needed for high-performance fueling with the Shin Yea Intake Manifold Spacer. Specifically engineered for "Cygnus-style" cylinder heads, this spacer provides an essential 9mm of additional height. This clearance is critical for builders running oversized carburetors on 232cc or larger GY6 projects, preventing interference between the intake assembly and the scooter’s frame or engine casing.

Technical Performance Features

  • Precision Tapered Bore: Features a professional taper from 35mm on the intake side down to 32mm at the engine side, maintaining high intake velocity and smooth airflow into the head.
  • 9mm Vertical Lift: Provides the exact offset required to clear the starter motor or frame rails when upgrading to larger PE, PWK, or TM series carburetors.
  • Complete Installation Kit: Comes ready to install with two high-temperature gaskets, ensuring a vacuum-tight seal right out of the box.
  • Made in Taiwan: Manufactured by Shin Yea, a leader in GY6 performance, utilizing high-grade aluminum to resist warping and heat-soak.

Comprehensive Fitment Guide

This spacer is designed EXCLUSIVELY for high-performance Cygnus-style heads and will not fit standard GY6 150cc engines:

Engine Type Build Compatibility
GY6 150cc (Cygnus Head) Specialized 4-valve or oversized 2-valve Cygnus-style conversions
Big Bore Builds Ideal for 212cc, 232cc, and custom long-stroke 4-bolt engines
Standard GY6 WILL NOT FIT standard 2-bolt 152QMI/157QMJ heads

Specifications

  • Bolt Hole Spacing: 50mm
  • Inner Diameter (Top): 35mm
  • Inner Diameter (Bottom): 32mm
  • Spacer Height: 9mm

Regulatory Notice

This product is not intended for use on public roads or land.

Mechanic's Note: When building a 232cc monster, every millimeter of clearance counts. Pro Tip: Use a tiny amount of gasket sealer on the spacer surfaces to ensure 100% vacuum integrity. Because this spacer adds height, double-check your **Throttle Cable** length to ensure it doesn't bind when the engine is at full travel!
