Tune your carb properly.its too lean tuned as a result engine is heating a lot. Also mileage is less due to too lean setting.

That incident was an year ago sir. But you are right, the tuning was very lean.

At that time it was tuned by the local mech. Later i learnt carb cleaning and tuning from this thread and now the tuning is almost perfect.

Now my bike is like-

1. In the morning, Starts at the first crank itself. No choke required.

2. max mileage i got= 80 kmpl that too only once. ( At strict 40 kmph, its very hard to sustain that speed )

3. Normal mileage = 65-70 kmpl ( at 50-55 kmph ) and around 60 kmpl (At 60+ kmph)

But the thing I've noticed is, not only my bike but all the PRO series bikes which I've ridden are very eager to reach upto 95 kmph but refuse to climb further.
Maybe the shorter gearing and the catcon are the culprits.

And [MENTION=28527]sibun[/MENTION] sir I have three questions which I am asking just out of pure curiosity. It may sound really funny but please bear with me.

HH had launched a bike called ' Dawn '. Its not a Joy or a CD-Dawn but it looks extremely similar to your Joy. How is this bike different from the other two bikes ?

Does the mahindra centuro use a Honda cub derived engine ? It appears extremely similar from the outside and also has a very similar exhaust note. and its more frugal too.

The hero ismart 100 or the 102 kmpl bike as marketed by hero. Yeah it seems to be an unrealistic figure but many many auto-journo agencies like Motorbeam, Overdrive etc had tested this bike and found that it can achieve 96-98 kmpl in actual riding conditions. Moreover my uncle has bought an ismart at it returns a consistent 90 kmpl. Even Honda had argued that Hero is making a false claim and the motor is not capable of achieving such high mileage. So how is it possible that this bike gives 90+ kmpl while other bikes hardly achieve 70+ in daily riding conditions ?

Coming back to xbhp app after a long time.
not able to get proper mileage in 2016 model hero splendor plus.after a lot of research.I put total 1.5 turn in carburator previously it was at 2.5 full turn (1turn is 360).without starting the engine.
After turning it to 1.5 turn .when my bro comes back home after riding 60km the rpm increases.is it means that the tunning is right?

[MENTION=28527]sibun[/MENTION] da , my 35k run BS3 super splendor has hard downshift problem. I've installed new chain sprocket and also clutch freeplay is also right, but my clutch cable makes slight sound while pressing it. Pickup of the bike is also good, i think my clutch plates are ok, kindly provide me a solution for hard downshifts.

Could you please tell us how to assess from Spark plug, if the bike has too lean setting ?

Show me a photo of your carburettor.

I want to see which mode.

Then I will tell how to tune.

This is the carburator[ATTACH]250143[/ATTACH]

Dawn was launched after joy. Joy sold exactly 15000 pieces. Then dawn was launched. Joy had an ex showroom price of 42k and dawn had an ex showroom price of 38k.

Joy had three short comings:-
1. Front shock absorber was from cd100 which was thin and had less travel. This had forks from splendor. Lent it a good front end feel.

2. The front drum was a 110 mm on joy. Couldn't stop this heavy bike. Dawn had a 130 mm drum


3. Tyres on joy was 2.50-18 front and 2.75-18 rear. Dawn had 2.75-18 front and 3.00-18 rear.


Centuro has a modified version of honda cub. Even kinetic challenger and boss had the same.

The ismart engine is different. Has different combustion chamber design. Has low friction bearings. Ignition system is a multi processor unit with 10 maps.

And carburettor is different with TPS.

Help needed!!

I am having Hero HF Deluxe i3s March 2018 BSIV model. Done 7000 kms and 4 services.

.

Did you check the spark plug? What plug are you using. Please service the bike by yourself. Most of the service centres ruin the bike in the name of free service. My bike has clocked 86,000 kms and still delivers 72 kmpl. Carburettor has been cleaned only once, that too unnecessarily.
