Build your dream Classic 500 (UCE) the old-school way—without hunting 20 different part numbers. This complete EFI→Carb conversion kit replaces the electronic fuel-injection on the Classic 500 EFI with a factory-spec carbureted system using 100% genuine Royal Enfield / OE-grade components. Unlike “partial” or piggyback kits on the market (which often retain EFI electronics or skip hard-to-source charging/ignition parts), this kit is engineered to be end-to-end: charging, ignition, fueling, plumbing, and controls.

Typical owner profiles: riders frustrated with aging EFI hardware, tourers who want trailside serviceability, and classic purists who prefer a mechanical carb and manual tuning. 

Key Features

• Truly complete: fueling + ignition + charging + plumbing + controls (not a piggyback).

• 100% OEM / OE-grade parts for durability and perfect fit.

• Pre-matched carb (baseline jets for 500 UCE, ethanol-safe hoses).

• Direct-fit sub-harness & TCI/CDI—no cut-and-splice loom hacks.

• OE tank petcock + adapter hardware to replace EFI pump assembly. 

• Reversible: keep your removed EFI parts; kit doesn’t weld/modify the frame.

• Tuning pack: baseline jetting table + idle/mixture procedure.

• Support content: we reference known community procedures to reduce workshop trial-and-error. 

Compatibility Table 

*Production years vary by market; Classic 500 EFI existed through late BS4 in many regions.

FAQs

Q1. How is this different from other kits online?
Most kits are partial or piggyback (retain EFI electronics or skip charging/ignition). We provide a complete, all-OE pathway—including magneto, TCI/CDI, loom and petcock—so workshops don’t need to source extras. 

Q2. Will performance improve?
With correct jetting and a healthy engine, throttle feel can be more “analog,” and dyno gains are reported by Amal/aftermarket vendors; results vary with altitude/exhaust/airbox. 

Q3. Is this street-legal?
Depends on your region. Converting EFI to carb can violate emissions/registration rules. Buyer is responsible for compliance.

Q4. Can I revert to EFI later?
Yes. No chassis cuts; keep your EFI hardware.

Q5. Do I need a new wiring harness?
Complete wiring harness ignition coil and cdi is there in the kit.
