Product Description

The UCD29-16-E20 is a Constant Vacuum (CV) carburettor that features a built-in Throttle Position Sensor (TPS), which is essential for the ignition timing maps of BS4-compliant engines. This “E20” version is a critical update for riders who want to prevent the premature hardening of rubber diaphragms and the clogging of jets caused by ethanol-induced debris.

Manufactured by UCAL Fuel Systems, this unit maintains the 29mm venturi diameter for optimal airflow but uses upgraded internal metallurgy and synthetic seals. It is the core component of the Royal Enfield official E20 retrofit kit (often paired with Part No. RLT00240/A), designed to restore factory-perfect idling, smooth mid-range acceleration, and consistent cold-start performance on the BS4 platform.

Key Features:

Ethanol Protection: Equipped with E20-compatible internal O-rings, gaskets, and a reinforced diaphragm that will not swell or degrade when using 20% ethanol petrol.
Integrated TPS Sensor: Features the correct 3-pin Throttle Position Sensor required by the BS4 ECU to manage spark advance and emission controls.
Improved Atomization: Precision-machined emulsion tubes and jets ensure a finer fuel mist, leading to cleaner combustion and better fuel economy.
Direct BS4 Replacement: Specifically calibrated for the 346cc UCE engine weight and power delivery, serving as a direct bolt-on for the original 576583/C unit.
Stable Idle Control: Upgraded bypass circuits help maintain a rock-steady idle even during the higher operating temperatures common with ethanol-blended fuels.

Technical Specifications:

Part Number: UCD29-16-E20 (RE Reference: RLT00240/A / 576583/E)
Brand: UCAL Fuel Systems Limited
Type: CV Carburettor with TPS
Venturi Size: 29 mm

Note: This is the BS4-specific unit with a TPS. If you have a BS3 bike without a TPS, the BS29-19-E20 is the correct choice.
