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

@blogging wheels- replied in the extreme thread to your query [MENTION=29030]Pinaki[/MENTION]- i will surely find a way out to fit it in existing box give me some time.And regarding the cone set balls i forgot to tell you that what you have seen is the new model racer balls at shop which are bigger in size, but ours are smaller model balls. I will post a picture of both balls side by side.

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

Can someone explain what are the changes made to Splendor in 2000 to make it compliant to emission norms.
Pre-2000 Splendors were having a nice loud exhaust note, very good low end torque (that the current Spendor's are missing), slightly better power, better mileage - this is what I hear and also experienced to some extent.
I can see a cat-con silencer, a mechanism that gives air to exhaust port (correct me if I am wrong).

So the strict emission norms did lot of harms to the original Splendor?
Pre-2000 Spendors are much in demand in my hometown (Kerala), even now.

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

No.
Y2K models developed more power and torque.
Silencer was modified by increasing length with suppressor baffles to meet sound pollution norms.
A Pulse secondary air injection(PAIR)system was added to meet CO emission norms. This basically injects fresh air in the exhaust port to convert any unburnt CO in CO2.
Needle jet was changed- Main jet to #105 & pilot jet to #38.
Flywheel mass ,cam , CDI and tuning were also changed. Some minor changes to piston and head.
Handle bar length was increased.
New clear MFR headlights and tail lamps.

Overall, old splendor was fun to ride with its loud exhaust note. Splendor plus had a unique exhaust note which gets better as the Rpm increases.

Y2K splendor remained almost untouched from 2003 to 2010 feb. In mid 2010, splendor was launched with a cat con in silencer and some tweaks here and there. Due to the addition of cat con, low end torque suffered. Pinaki ji has not changed his splendor's silencer to that of Y2k even now.

I might have missed some points, Sibun will add further info.

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

Yes , my Splendor+ ( 1st July 2010 ) is the first batch of the new cat-con models . Infact my bike was ready for delivery but then suddenly it dissapeared from showroom . I complained to HeroHonda and they told me that all bikes have been recalled mid-way to factory for refitting to the new compulsory emission norms for the four metros . It took another one month then for delivery . I've not found the guts to change the exhaust yet although I very much love the original Chrome Splendor exhaust ( which I think looks fabulous on this bike ) . Otherwise it's working just fine .
I have always preferred torque in my bikes . But alas in this aspect I find my Splendor+ a leeetle bit wanting . The new DC ignition engines are a bit more torquey and peppy and I liked it on my friend's new HF-Dawn in every way .
Very much possible explanation . Although they appeared to be same size to me , I could not have possibly defferenciated between 4.76mm and 6mm by naked eye . Anyway Bajaj's OE balls ( 4.76mm ) have fitted into my cone-set and working just nicely now . I shall buy the skf caged bearing in the meantime and store it . Front shocks oil & seals is purchased and ready but could not do it because it's raining cats & dogs almost everyday now . Bike is caked with mud .

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

Why ? New Silencer is cheap and fitting takes no more than 5 mins. It will be the best investment on your splendor .

Tools required
#10 T-spanner, #17 and #14 ring spanners.

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

Thanks Shoeb.
But what I've heard from pre-2000 Splendor owners are they're getting 70+ kmpl in city, while my 2001 Splendor has never given more than 65 kmpl even on highways.
I think I've read about the low mileage of new Splendors here in this thread itself.
Also I felt those old Splendors' pulling power to be better when ridden couple of times.

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

Hello guys this is my first post in this thread...
I have been a silent observer from a long time and I learned a lot from this thread.
I followed @sibun's guide for carburetor tuning and did it on my Pulsar UG 4.5 and these are the pictures of my spark plug after tuning the carb.

I read that reddish brown was an indication of perfect mix and generally observed in fuel injected engines.


The bigger spark plug is from my '03 Zen Mpfi !!


After nearly 3 years of owning a motorcycle i am now able tune the carb up to my satisfaction !!!
Engine sound is awesome, the grunt of the engine is back, sounds good when the engine is hot.
I'm getting mileage figures of about 50-55 Kmpl easily.
Once again I would like to thank @sibun for his amazing guide on carburetor tuning.

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

Y2K splendors were best of all the splendors. It came out with my Joy in 2001 and changed the face of hero. It was with this model that splendor become highest selling model of all times.

Changes were any like bigger main jet, secondary air injection, rear sprocket was changed to 43t from 45t, cdi was re-mapped, silencer was lengthened with addition of four baffles(baffels but no cat cons), Fly wheel was made lighter for the engine to pick revs quickly top speed increased to 90+ kph true speed, e.t.c.

Regarding the pre 2000 splendors being better then it is just a mis-conception in peoples mind as we know how much normal people know about bikes. Generally if they hear something in market then it becomes a craze.
The old model having better low end torque then let me add that they run 45t sprocket which gives them better low end torque, just fit 45 t sprocket in y2K splendor and you will not be able to leave clutch normally in first gear as everytime it will do a mini burnout. Although the pre 2000 model had better low end torque but cross 60 and they will become loud and struggle.
Pre 2000 splendors gave 70+ and 2001-2004 splendor gave 65 kpl. Again in 2004 when spl+ was launched the cdi was remapped and mileage returned to 70+ kpl.

Regarding low mileage then let me add that shoeb and pinakiji both were getting 65 kpl but after my help in tuning and all such they are getting 70+ kpl. In my Joy i usually get 75+ kpl easily and if it decreases below 70 kpl then i start to find the cause and it becomes more headache to my mechanic than me as the customers in my mechanic garage knows my joy well as it is the only joy they have seen, also it looks like new even after 13 years, and last they know one thing that it returns 80+ kpl.

Regarding better pulling power then i have expalined above. The pre 2000 splendor had 7.2 Nm @5000 rpm and y2k model have 7.5 Nm@ 5000 rpm. My Joy puts out 7.85Nm @ 5000 rpm, and contrary to popular belief the silencer of splendor and my Joy are different. In splendor sound is less bassy but in Joy the sound is bassy not like old model splendor but smooth bass sound. When it will be idling you can feel the strokes. Compared to it my CBZ extreme sound feels boring.

Glad that i was of some help to you. The thing is that none here knows the actual procedure. All have read somewhere in net, but my procedures are real experienced procedure and i have tried it before suggesting. You will be surprised to know that for me it took 5 years to master the art of carburettor tuning, and all thanks goes to my mechanic who is an expert in bikes.

And a bit of advice stay away from my posts otherwise you will become one crazy person like me. My family thinks that i have gone half mad after bikes. My sister thinks that i was born as a mechanic.

And some update:-

My Joy is needing a small service. The strokes on idling have decreased and also the pull, so next saturday will open the head, decarbonise and polish the valves and also clean the ports, change the sprocket kit with new DID kit, change the timing chain as slight noise is there and finally fill her up with SHELL RIMULA 15W 40 as the engine has run 70k from her last re-build so a diesel engine oil will be better.

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

Thanks Sibun.
From your above highlighted point, pre-2000 splendors had less torque than Y2K models. Is it right?

Me too was thinking, it is just a misconception that post-2000 models are crap, just people say based on some blind assumptions.
Again the doubt intensified recently when I recently read somewhere in xbhp that the post-2000 Splendors were inferior due to cat-con, secondary air injection etc.
I am not sure in which thread I saw it.

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

Sibun,
My father's CD Deluxe 2010 model is covered about 37k. Now there is small kat kat sound coming from clutch side while idling. Mild noise inside cylinder, I guess timing chain needs attention. Chain sprocket also need to change as the chain sprocket kit for CD deluxe is really thin and wear very fast even with proper care and lube. Can we use DID chain sprocket kit of splendor in CD Deluxe 2010 self start model?

Need your advice on list of parts to change and works to be carried on this midway make up.
Thanks.

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

Is there anything called engine decarbonizer ?

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

Cd Deluxe clutch housing is different from our old model clutch housing. All the new models like pro and deluxe series which shares new model engine clutch housing is different. The teeth of the housing is not like our old model straight but slightly helical like yamaha RX series. Also the clutch bell is different as in our old model all the four plates sit in one slot, but in new model it is like bajaj caliber where three plate sit at one slot and last plate in another slot. This type of clutch is stronger but the defect is that if you are riding the clutch then the bushes will wear out and also the GPT.

Your father must be riding the clutch which is normal with increase in age, so check the clutch housing and get it overhauled. Also change the clutch plates as they will be at the end of life. Change the timing chain with DID chain. For chain sprocket you cannot change to splendor y2k as it has smaller hub than CD deluxe. And thicker chain will make the bike lazy to pull. Go for DID chain kit for CD DELUXE/passion pro, and it will last.

The old model bikes has 428 pitch chain and new dawn/deluxe, pro series have 420 pitch chain. DID gives 420 pitch for even older models but the difference is that the quality of sprockets and chain is high as a result even though it is thin it last long. So go for CD DELUXE(new model) from DID.

Chain the timing chain and while you are at it clean the head and polish the valves.

The parts required are:-
1. Clutch housing repair in lathe,
2. Clutch plate,
3. Timing chain,
4. Chain sprocket kit,
5. Valve oil seal,
6. clutch cover packing, timing cover packing, magnet cover packing, magnet oil seal, top cover packing, rocker cover packing, head gasket(no o-ring as new model doesn't requires it).


Yes there is engine decarboniser. It is basically used to de-carbonise the head, but practically it is waste of money as in bikes it is easier and less costly to open head and clean it. More-over engine de-carboniser doesn't completely clean the head as in manual method.

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

Thanks Sibun. This bike is 2010 feb manufactured model. It has chrome silencer not black like latest Deluxe. The engine rated 7.7ps @7500 rpm and 7.95 nm @ 6000 rpm.
The next model comes with 7.8 ps @7500 rpm and 8.04 nm @4500 rpm. Can you get the clear picture now regarding my bike's generation?
How much is for DID cam chain and drive chain kit?

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

Hi Guys need some help. My dad has a Splendor NXG at my village in Cuttack. He has asked to get a spark plug for his bike. Whats the plug rating, as Hero service centre is quite far from where I stay, I would like to buy it from a nearby spares shop.

Thanks a lot in advance.

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

One problem was solved terribly and other one pops up.
it's glamour 2007.

About a week ago , a was washing the bike, an I found out that there was a bolt missing which holds the engine to the chasis.
So I go to service center to inquire about this exemplary work , they were unwilling to help, tried to talk to the manager but he ignored and pretended to be busy in some work (I’m sure he wasn’t) and I was directed to a guy.
He took about one hour to fetch that missing bolt .
I also asked about the quality of the crankcase as its color seemed to be rough as compared to the crankcase which was originally on the engine. But he said nothing can be done about it and they come as it is .

I also asked him about the tick-tick-tick noise that was coming from the engine , he said he doesn’t find anything unusual in it , it’s ok.

Then he revs the bike and whitish smoke comes out the exhaust.
---> He says the engine oil is going past the piston into the combustion chamber and
the entire piston head assembly needed to be replaced . Approx.. expenditure told = 3500.

Now two days back I was riding it , and the chain lock broke , I managed to safely steer the bike to the side of the road..Another example of their great work.

Now after riding this for almost 165 kms , I find the engine oil level which was at the top of the oil level indicator window (higher than the max mark position), has come down to the max mark .
Is the oil really leaking into the combustion chamber.

If it is so , then please tell me :

1. Obviously for this , the whole engine will be opened so what other parts should I get replaced so that it lasts for some good time. (odometer reading = 33650)
2. Please mention the approx. price, brand and how to identify a genuine item

Don’t want to go to the so called authorized service center , a hunt for good mechanic is on , but chances seem to be bleak .

I ‘m much obliged for your help.
