Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Small update from my side. Passion pro is running fine. Clocked more than 86,000 kms and still going strong. Never got bored of the bike. A small issue has arised now. The brake light switch in the front brake is not working. The brake light is on all the time. The bike stood under heavy rain for a night and this happened. Will fix this soon.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion


Thanks for clearing my curiosity sir. I wonder why Hero pulled the ismart 100 off the market so early. It was the third most fuel efficient motorcycle in india, the first two being the glamour PGM-Fi and old bajaj platina.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Hey all, i have a splendor pro, am wondering if it can be made into splendor cafe racer with karizma engine swap.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Yours I the model with TPS

So tuning it requires tuning at low rpm than old models.

Just increase the idle to 2000-2200. Then start the afr screw from 1.5 turns


Turn in or out. See which way it's increasing. Find the right spot where its highest idle.

Then decrease idle to 1100 using idle screw. That's your correct afr.

Tuning by turn method is the most useless advice I have heard.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

This is the carburator

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Modern day engine are lean burning engines.

And spark plugs used are hotter plugs.

So correct tune is reddish white.

A powdery white is lean tune.

And a blackish red is lean tuned

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Change the clutch cable. It's not dis engaging clutch fully.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Show me a photo of your carburettor.

I want to see which mode.

Then I will tell how to tune.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

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.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

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

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

We also are interested to know, please !

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

[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.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

I will reply to all your query in evening. Also a surprise for old splendor owners who are worried about headlight woes.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

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?

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

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.

----consecutive posts auto-merged-----

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.

1.

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 ?

2.

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.

3.

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 ?
