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.

Preguntas frecuentes sobre compatibilidad
¿Esta pieza es compatible con mi modelo y año específicos?
This four-piece intake boot set is designed for compatible:
1980–1982 Suzuki GS750E
1980–1981 Suzuki GS750L
1982–1983 Suzuki GS750T
Your original intake pipes should match the 13111-45400 / 13121-45400 family and have the same dimensions, carburetor openings, clamp positions, and overall shape shown in the product images.
Do not rely only on the “GS750” model name because earlier GS750 generations use different intake boots.
¿Necesito que coincida el número de pieza OEM?
Yes. Matching the OEM reference is one of the most reliable ways to confirm compatibility.
Common Suzuki references for this application include:
13111-45400
13111-45401
13121-45400
Your motorcycle may use two intake-pipe positions across the four-cylinder engine, so more than one OEM reference can appear in the parts catalog.
J38-13596-00 is not a Suzuki OEM number and should not be used to confirm GS750 fitment.
¿Qué modelos o situaciones no son compatibles con esta pieza?
This intake boot set is not confirmed for:
1977–1979 Suzuki GS750 models using earlier 13110-series intake pipes
Suzuki GS750 models using different intake-pipe numbers
Suzuki GS850 or GS1000 models unless independently verified
Motorcycles fitted with aftermarket carburetors requiring different boot diameters
Engine-swapped or heavily modified motorcycles
Applications where the original intake boots have a different shape or size
Bolt-on metal intake spacers using gasket-style mounting
Yamaha applications using OEM J38-13596-00
Do not assume all Suzuki GS-series motorcycles use the same carburetor intake boots.
¿Qué debo verificar antes de hacer un pedido?
Before ordering, confirm:
Suzuki GS750E, GS750L, or GS750T model
Exact production year
OEM intake-pipe numbers
Carburetor-side opening diameter
Cylinder-head-side opening diameter
Approximately 49 mm / 1.93 in overall length
Clamp-groove locations
Boot shape and orientation
Quantity of four required
Product photos compared with the original parts
Also inspect the intake clamps, carburetor synchronization, sealing surfaces, airbox boots, vacuum connections, and surrounding fuel-system components for additional wear or leaks.
