Royal Enfield E20 Carburettor Upgrade Kit for UCE 350 BS4 Carb Bikes (Black Tank Sticker Included) – KLT00004/A
Genuine Royal Enfield OEM E20 Fuel Compatibility Upgrade – Restore Smooth Performance and Protect Your Carburettor System!
The Royal Enfield KLT00004/A E20 Carburettor Upgrade Kit is an authentic factory solution designed for UCE 350 BS4 carburettor-based motorcycles. As ethanol-blended fuels such as E20 become standard, older carburettor seals and jets can deteriorate, leading to poor idle, hard starting, or inconsistent fuelling. This upgrade kit renews your carb’s internals with OEM-grade, ethanol-resistant components for improved reliability and fuel compatibility.

- Fixes common issues: Hard starting, unstable idle, hesitation, and rich/lean fuelling behaviour
- Includes: E20 fuel tank label (black sticker) supplied inside the kit
- OEM-grade seals and consumables: Reduce leakage, swelling, and fuel seepage risks
- Ideal use: Preventive upgrade or during carb overhaul and tuning service
- Workshop friendly: Compatible with standard carburettor tools and installation practices
- Return prevention: VIN + carb photo verification recommended before dispatch
