144732/A Royal Enfield Carburettor 350cc (Mikcarb VM24 Type) for Bullet 350, Electra 4S/5S, Machismo, Campus – Genuine OEM

If your older carbureted Royal Enfield 350 is suffering from hard starting, unstable idle, flat acceleration, or poor mileage, it’s often the carb body + internal circuits that are worn beyond effective “local repair.” The 144732/A Carburettor 350cc is a genuine Royal Enfield spare, supplied to match OEM fitment standards and restore factory-like fuel delivery and rideability. 

This part is catalogued for legacy 350cc carb models such as Bullet 350, Deluxe, Machismo, Campus, and Electra 4S/5S variants, making it the correct choice when you want OE-level reliability instead of tuning headaches from low-grade copies. 

Important: This is not meant for UCE Classic 350 / Standard 350 BS3-BS4 “BS29” carb bikes or any EFI/J-Series models. If your bike uses the BS29/UCAL carb platform, choose the correct BS29-series carb/part instead (to avoid wrong fitment and returns).

FAQs 

Q1) Will 144732/A fit my Classic 350 UCE (BS3/BS4) with BS29 carb?
No. Classic 350 UCE carb models typically use BS29/UCAL platform parts, which are different from this legacy VM24-type carb. Ordering this for a BS29 bike is a common mismatch that leads to returns—please match your current carb model/markings first. 

Q2) How do I confirm this is the right carburettor for my bike before I order?
Check (a) your bike’s exact model family (Bullet/Deluxe/Machismo/Campus/Electra 4S/5S), and (b) the carb type/markings on your current unit. This part is commonly referenced as Mikcarb VM24 for 350 applications in parts trade listings. 

Q3) Is this genuine Royal Enfield or aftermarket? Why does it matter?
This part is listed as a Royal Enfield genuine spare by official-parts partners and dealer catalogs. Genuine carbs typically reduce issues like inconsistent jetting, poor casting quality, air leaks, and repeated tuning problems seen with cheap copies—especially on long rides and daily use. 

Q4) My bike starts but bogs on throttle / idles high / backfires. Will replacing the carb fix it?
Often yes—if the carb body, slide, or internal passages are worn. However, always inspect/replace basics first: air filter, intake rubber, throttle cable free-play, fuel line, and ensure there’s no air leak. If you’ve already tried tuning and the symptoms keep returning, replacing the carb is the cleanest OEM-grade fix.

Q5) Does the carb come pre-jetted and ready to bolt on?
It is supplied as the carburettor assembly, but final performance still depends on your bike’s state of tune (air filter, exhaust, altitude, and engine health). For best results, install carefully, set idle/air screw baseline, and do a short test ride + plug check.
