Why does one eAuto carburetor fit so many bikes?
Honda designed the CBF150M engine as a shared architecture across its Indian joint-venture. When Hero Honda launched the CBZ Xtreme, Hunk, and Achiever, all three used the same 149–150 cc OHC engine with an identical 26 mm CV carb specification. The eAuto carburetor is engineered for this entire platform — not a generic universal fitment.
❓ FAQ
Q: What is the price of eAuto carburetor for Hero Hunk / CBZ Xtreme?
A: Check the current price on this page — eAuto.co.in offers the best online price for this carburetor with free shipping and Cash on Delivery (COD) pan-India. OEM Honda carburetors cost ₹5,000–7,000 at dealerships; the eAuto carburetor delivers identical fitment at a fraction of the dealer price.
Q: Where can I find a carburetor for Hero Hunk / Honda Unicorn near me?
A: The eAuto carburetor ships to every pin code in India — Delhi, Mumbai, Bangalore, Chennai, Pune, Hyderabad, Kolkata, Jaipur, Lucknow, Nagpur, Bhopal, Indore, Chandigarh, and all tier-2 and tier-3 cities. No need to search for bike parts near me or spare parts near me — eAuto delivers to your workshop door in 2–6 days.
Q: What do eAuto reviews say about this carburetor?
A: eAuto reviews from verified buyers highlight direct bolt-on fit (no modifications needed), restored idle and mileage from the first warm-up, and same-day dispatch. Mechanics who stock eAuto carburetors report fewer fitment issues compared to generic unbranded alternatives from local markets. Read all eAuto reviews on the product page above.
Q: Is this an OEM / genuine Honda or Hero carburetor?
A: The eAuto carburetor is a premium aftermarket part — not a Honda or Hero OEM product. It is manufactured to OEM specifications for the 26 mm Keihin CV-type carburetor used across this platform. For genuine OEM, those are available at authorised Hero and Honda dealerships.
Q: My CBZ Xtreme is a 2013 model — does this eAuto carb fit?
A: Yes. The 2013 CBZ Xtreme (Hero MotoCorp, post-split) uses the same 149.2 cc Keihin CV carb as all earlier models. The carb architecture was unchanged after the Hero–Honda split in 2011. Confirm your bike is carbureted — the 2017+ Xtreme Sport uses fuel injection and requires no carburetor.
Q: Does the Honda Unicorn Dazzler use the same carburetor?
A: Yes. The Honda CB Unicorn Dazzler (2010–2012) is a styling variant on the same CBF150M platform — engine and carburetor identical to the Unicorn 150. The eAuto carburetor fits the Dazzler directly.
Q: Will I need to re-jet after fitting?
A: No. The eAuto carburetor ships with the correct slow jet (#38 Hero Honda / #35 Honda Unicorn) and main jet pre-installed. Basic idle and fuel-screw adjustment is all that's needed for a stock bike.

🔍 Symptoms
A failing carb on the Hero / Honda 150 cc platform is one of the most common workshop jobs across India. Here are the six clearest signs it is time to replace — not just clean.
1. Hard starting — especially when engine is hot
Worn float needle valve lets the bowl overflow, flooding the engine. The self-starter cranks but the bike won't fire. Common on high-mileage Hunk and CBZ Xtreme — consistently flagged as a carb replacement job, not a cleaning job.
2. Petrol dripping from the overflow pipe
Fuel pooling under the bike overnight. This is a worn float valve seat — it cannot be cleaned away. Continuing to ride risks hydrolocking the engine. Replace immediately.
3. Hunting idle — RPM surging at standstill
Engine idle swings between 800 and 1,800 RPM. Usually a cracked CV diaphragm that can no longer hold vacuum — often visible as a split near the diaphragm edge on removal.
4. Black smoke and petrol smell from exhaust
Rich mixture from a stuck air-cut valve or gummed jets. If two cleaning cycles haven't fixed it, the body is corroded. A fresh eAuto carburetor gives you new jets, new air-cut valve, and new diaphragm in one part.
5. Mileage dropped more than 8–10 km/l from normal
Unicorn rated 60+ km/l new; CBZ Xtreme and Hunk at 50–55 km/l. If your bike falls below 40 km/l after a carb clean, the jets and body are beyond restoration. The eAuto carburetor restores factory fuel economy — the most common positive note in eAuto reviews from Hunk and Unicorn owners.
6. Throttle flat spot between 2,000–4,000 RPM
Dead zone mid-range when opening the throttle. On the Hunk's TPFC system, a worn accelerator pump creates this lag. The eAuto carburetor is fully compatible with the TPFC mechanism — swap the whole unit and the flat spot is eliminated.
eAuto Tip: If the bike has been sitting unused for 6+ months, replace the carb rather than cleaning it. Stale petrol varnishes the needle jet in ways ultrasonic cleaning cannot reverse. An eAuto carburetor replacement costs less than two cleaning sessions at most workshops.
🔩 Installation
A 30–45 minute job for any experienced mechanic. Tools: flathead screwdriver, 8 mm and 10 mm spanners, hose clamp pliers.
Step 1
Turn petcock OFF — drain float bowl
Switch fuel tap to OFF. Open float bowl drain screw to empty residual petrol before removal.
Step 2
Remove side panel and air filter box
On Hunk / CBZ Xtreme, remove the right side panel first. On Unicorn / Achiever, air box is accessible from under the seat. Disconnect the air filter hose clamp from the carb inlet.
Step 3
Disconnect cables and hoses
Loosen throttle cable adjuster locknut and slide cable out of carb top cap. Disconnect fuel inlet hose, overflow pipe, and breather hose. Label them before removal if unfamiliar with the engine.
Step 4
Pull the carb from the intake boot
Loosen the intake-boot clamp bolt (8–10 mm). Twist carb gently and pull towards you. If the rubber boot is brittle or cracked, replace it now — a cracked boot causes air leaks that no carb replacement can fix.
Step 5
Fit the eAuto carburetor
Slide the new eAuto carburetor into the intake boot — rotate gently if tight, never force. Reconnect all hoses in the same positions. Route throttle cable through the top cap with 2–3 mm freeplay at the grip.
Step 6
Refit air filter — open petcock — check for leaks
Reconnect and clamp air filter hose. Refit side panels. Open petcock and wait 30 seconds for float bowl to fill. Check for fuel seeps at inlet junction before pressing the starter.
Step 7
Cold start — set idle — done
Use choke for cold start. Let engine warm 5–8 minutes. Set idle to 1,400 ± 100 RPM. Turn fuel screw to 2.5 turns out as baseline — adjust ¼ turn at a time. A stable warm idle confirms perfect fitment.
