Genuine Royal Enfield C.O Emission Kit (Without Air Filter) / Carburettor Flange Assembly VM24 | Bullet 350 (CI) / Electra 4S / Machismo | 112089

The Royal Enfield C.O Emission Kit (Without Air Filter) – Part No. 112089 is a genuine OEM kit used on older carburetted Royal Enfield 350 models, commonly referenced for Cast Iron (CI) Bullet 350 applications and also listed by dealers for legacy models like Machismo and Electra 4S.

On dealer catalogues, this part is described as “C.O EMISSION KIT W/O AIR FILTE”, and is also referenced as a carburettor flange assembly for VM24—which makes it relevant during carburettor service/overhaul, emissions tuning setups, and restoration jobs where the original intake/carb mounting hardware needs to be replaced to avoid air leaks and inconsistent idle. 

Because this is a fitment-sensitive carb/intake-related part, ordering the exact part number matters. This listing is intended for the confirmed legacy models below only. If you are on UCE / EFI / J-Series / 650 Twins / Himalayan, do not buy this unless your parts diagram specifically calls for 112089.
