Hope you saw my earlier post. I’m getting a decent mileage of 48.35kmpl average. And I always tested full tank to full tank method (there is a mark inside the tank that I always refer when I say full tank and not to the brim).
And I always touch 80+ in open city stretch. Also my commute is in peak hours.

Importantly, do not check the mileage by just filling petrol for ₹100 or 1 or 2 liters. Ideal method is either to check reserve to reserve method.

So please have your bike checked properly as Hornet is a very reliable bike when you compare power+performance+mileage.

And mileage is mainly dependent on the rising style as well. May be individuals braking and acceleration method may vary drastically.

I will try the HP power petrol today since I have hit the reserve already. I always try to warm up for a minute by putting it on the choke alone and it seems to do wonders for throttle response in Cold starts.

Hi all, I have a weird mileage issue in my bike. During the first 1000 Kms, I got an average of 33 Kms, with normal driving, never above 90 kmph and a decent break-in. I went to the service center (Tansi Honda, Ramagondanahalli), they performed a mileage test, and driving at ~40kmph, they managed to get 47 kmpl. They said they will do some adjustments, and did some tappet adjustment, reduced the idle and gave the bike back to me. This time, I got around 36 Kmph, with very fuel economy mindful driving. When I took it back, they refused to take it, had to argue for 3 hours before the Service General Manager himself took for a test drive, drove normally with around 50 kmph top speed and got only 40 kmpl. I told him this is how it is and if I cruise at 60 kmph, this goes down even more. He agreed, took the bike, and they replaced Jet needle in the carb and gave it back, claiming they got 60 Kmph when driving in economy mode. I drove, and surprise, I got 36 km. I figured there might be a very minor leak, and closed the petcock every night. Ended up getting 42-46 kmph. 45.6 kmph when cruising at 90 kmph on a trip to Vellore. However, if I left the petcock on, the poor mileage returns. The ASC tried to reproduce the issue, but they could not, and got 44 kmpl for a litre, with the fuel cock on over the course of three days. I took it back, filled with 100 Rs worth of petrol on friday, and bike hit reserve on Monday with 36km on the trip meter. Note that there is no way someone is stealing the fuel. The vehicle is in shade both at home and office. What could be the issue? The mechanic told me that people only get 35 kmpl in Hornets. Is it true? Is it possible that the carb might be slowly leaking fuel so that I see a mileage issue only when I take longer to consume a litre of fuel? My next step is to get a Mileage testing bottle, fill it with some petrol and let it hang overnight to see any reduction in fuel level. My suspicion is that there is some minor issue with the float. How do I prove it? The AFR is perfect since the mechanic showed be a good maroon burn in the Carb. He is very polite, hence I don't wish to override him, but he says he cannot report this to Honda and get the Carb replaced since he cannot reproduce the issue. What do you think I should do?


Sorry for the long post. Any help is appreciated.


Thanks

I doubt your riding style...
My friend owns hornet, he gets around 50

As I had mentioned in the post, even I was able to get good mileage at times. I figured there might be a very minor leak, and closed the petcock every night. Ended up getting 42-46 kmph. 45.6 kmph when cruising at 90 kmph on a trip to Vellore. However, if I left the petcock on, the poor mileage returns.

Looks like we should not run the engine on choke for more than 15 seconds. I found this in owner's manual. Probably that is also another reason you end up wasting fuel.
About 15 seconds after the engine start
push the choke knob all the way to fully
OFF (B). If idling is unstable , Open the
throttle slightly. - Page 37 of owners Manual

I noticed a passer by Hornet in city and the chain was rattling like loud chain saw. [emoji33] ,
Guys, take care of chain clean and lube.

Recently, I got WD40 and it seems it loosen up chain joints better than 3M chain cleaner. Rear wheel is rotating more freely. [emoji106]
