Intake Manifold Boots for Suzuki GS750E GS750L GS750T 1980–1983

Product Overview

Restore a secure and properly sealed connection between the carburetors and engine with this four-piece carburetor intake manifold boot set, designed for compatible Suzuki GS750E, GS750L, and GS750T motorcycles.

These intake pipes replace original carburetor boots that have become cracked, hardened, loose, distorted, or difficult to seal after years of exposure to engine heat, vibration, fuel vapor, and age.

Worn intake boots may allow unmetered air to enter the engine, potentially causing unstable idle, hanging RPM, difficult starting, hesitation, inconsistent throttle response, or uneven engine operation.

Designed for compatible Suzuki applications using intake-pipe references 13111-45400 / 13121-45400, this four-piece set restores the carburetor-to-cylinder-head intake connections when the dimensions and physical configuration match the original parts.
