Royal Enfield Carburettor Assembly – Part No. 576583/C for 350cc UCE BS4 (Classic, Bullet, Thunderbird)

Product Description

Restore your engine’s heartbeat with the Genuine 576583/C Carburettor Assembly. This assembly is a direct OEM replacement for the aging or malfunctioning units on your BS4-compliant Royal Enfield. It ensures a perfect stoichiometric ratio (the ideal mix of air and fuel) across all engine speeds, providing crisp throttle response and stable idling.

Constructed from high-grade aluminum alloy, this 29mm venturi carburettor is built for longevity and consistent atomization. It is designed as a “plug-and-play” module, compatible with your stock intake manifold and airbox, making it an essential fix for issues like poor cold starts, fuel leakage, or engine hesitation.

Note: This legacy part (576583/C) has been officially superseded by RLT00240/A. The new version is fully compatible and adds E20 (20% Ethanol) fuel validation for modern petrol blends.
