Carburettor Rubber For Royal Enfield Bullet Old Model

Ensure an airtight intake system with this Premium Carburettor Mounting Rubber. Specifically designed for the Cast Iron (CI) “Old Model” Bullets, this rubber sleeve (also known as a manifold boot or bellow) provides the critical seal between the carburettor and the engine intake. A worn or cracked rubber leads to “lean running,” erratic idling, and engine overheating—making this a vital part for vintage bike maintenance.   Key Features: Vintage Fitment: Engineered for early Mikcarb (Mikuni) and Amal carburettor setups found on Bullet 350 and 500 models (Pre-UCE). Fuel-Resistant Material: Manufactured from high-density, oil-resistant nitrile rubber that resists degradation from petrol vapours and engine heat. Airtight Seal: Precision-molded to provide a snug “push-fit” over the carburettor venturi and the intake manifold, preventing vacuum leaks. Vibration Dampening: The flexible rubber construction absorbs engine vibrations, preventing the carburettor from frothing the fuel in the float bowl. Flexible Installation: Easily secured with standard hose clamps (jubilee clips) for a reliable, tool-tight seal. Specifications: Compatibility: Royal Enfield Standard 350, Bullet 500 CI, Machismo, and early Electra models. Material: Heavy-duty reinforced rubber. Inside Diameter: OEM Standard for Mikcarb VM24/VM28.
