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

No tweaks , in fact it has less modifications from the original Honda design - since there are almost no environment norms in Pakistan . There is lots of complain about the rear shocks - not because of lack of adjustment , but for losing shock-absorbtion action quickly . There is complain about the gearbox ( hard & noisy ) too . The chain-case is optional and comes in both silver & black .

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

Hence proved whatever they try, you can never beat Hero Honda Splendor series bikes..Built like tank always 1st rank..

On other note not having emission norm would actually allow them to get more power as they can remove catcon and bump up compression to get even more performance isn't it??

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

Alas yes . No air-induction valve means less complex engine , no catcon means free-er exhaust and more low end and overall torque etc advantages . Sweet exhaust note of the first series CD100ss & Splendors possibly too - something I really miss . I remember that I was riding an RX when these hero-hondas came to the market with a bang and we were so thoroughly envious of them then and ever since - me , mainly because of the sweet exhaust note .

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

Will removing the cat con in our rides give any change to the note. I have a spare silencer to test

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

Yup sure does,it makes note more bassy and thumpy. Ride any old bike it will feel more like a one with free flow exhaust one. Try it once.

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

Let me clear some doubts and myths regarding air-induction valve (pulse secondary air injection).

1.It does not cause any perceptible loss in FE.
2.It does not cause any loss in power/ torque.
3.It does not make the mechanicals complex.

Air induction valve simply injects fresh air into the exhaust port to lower carbon monoxide emissions. It is a simple valve which injects air during acceleration and upon deceleration, it does not inject any fresh air (to prevent popping sound due to afterburn).
Also, As per sibun, it also recirculates some tiny amount of exhaust gases into intake.

Just think- If the introduction of air-induction valve resulted in loss of power then Y2K models should have had power less than 7bhp.


2010 onwards spl+, the exhaust is restrictive to reduce HC emissions and noise. In splendor +, even without a catcon, it will pass pollution test with flying colors.
With the introduction of Pro models, this problem was re-addressed with change in ignition timing, CDI map etc..

@Pinaki ji
My humble suggestion to you, please swap the silencer with the Y2K type. 18350-KCC-941 MUFFLER COMP., EXH.

@sibun
Please correct me if I am wrong.

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

Very well said [MENTION=14414]shoeb[/MENTION], was complete pleasure to read it.So lets forward it to me for more clarification.Some of the myths associated with secondary air injection are:-1. Loss in fuel efficiency- One of the greatest myths and nothing else. One of the best example is my Joy. It came around year 2001 and has SAI but free flow silencer although longer silencer. I can challenge any one be it old or new model bikes for mileage test.Some incidents:-A):- When i was studying in college, most of the time classes will be suspended and we two friends will fill fuel and roam aimlessly with no aim just to take the pleasure of riding. At that time my bike used to return 90-93 kpl most of the time.B):- Once during college when my friend and i decided to test mileage we just filled one liter of fuel when bike hit reserve and we roamed aimlessly at a speed of 45-50 kph gossiping among ourselves and we were surprised to note that bike is not hitting reserve for so long. The mileage returned was a staggering 106 kpl and we re-tested it again in 4-5 days gap and again the same result.My joy is still returning a mileage of 75-78 kpl with a worn crank and a bad power coil. Will change power coil and will easily return 78-80 kpl without fail.2.Loss of power/Torque:- Let me add here that the old model CD100 and splendor made 7.2 bhp and 7.2 Nm torque but my Joy which is a bike with Y2K changes makes 7.7 bhp@8000 rpm and 7.85 Nm @5000 rpm.My uncle and me with both up has touched 105 kph on speedo easily. With me alone have touched 110 kph on speedo easily.Also would like to add one incident here that once while returning from my hometown to Bhubaneswar with my mom as pillion i was constantly maintaining 70-80 kph the whole way of 117 km and bike returned 75+ kpl. I reached the place in 1.45 minutes.Also same thing when i was going from BBSR to my hometown the distance of 117 kph, i covered the distance in 1.25 mins, so calculate the average speed. A feat that i have not dared till now on my extreme.3. Complexity- Nothing complex as it is just a valve that works on principle of air pressure which operates a bucket valve that injects fresh air into exhaust port to reduce CO poisoning by converting CO to CO2 which can be absorbed by Plants and trees.In this 13 years of ownership it is now that the valve have given problem and when i will overhaul the engine will replace it.4. Engine reliability:- My bike is at 3.45 lacs now. The first time engine was opened at 1.25 lacs kilometer and that too engine was not smoking. Second time engine was opened at 2.35 lacs but the OE piston in new bore kit was seized at 15k kms. Bored out the block and used 0.25 size piston from Mahle. That idiot at lathe made the piston so much tight that after 15k crank sound came. Changed the bore to USHA and re-built the crank at 2.60 lacs all because of faulty piston and bad job by lathe in second instance. Now bike has run 85k after overhaul and still runs like new with very hard compression. Slight crank noise is coming because crank has been re-built three times which is a lot for the crank. This time will plonk a new crank with new bore kit and bike will easily run for 1.5 lacs km with no overhaul.So you all can see that all those are myths and nothing else. All those complaints that you see in new bikes are most of the time manhandles by customers by ripping new bikes. What will you tell when a new splendor pro with no number overtakes me on my extreme at 80 kph , will that bike engine last or return good mileage.

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

Thanks for clarifying this again.
The pre 2000 Splendors are in high demand and people say Hero Honda has done something bad to the Splendor on the Y2K model and the pickup/power is gone!
I think the feeling we have on riding pre 2000 model splendor is due to the bullet like exhaust note it produces and has nothing to do with the engine characteristics.

But as a matter of fact, my 2001 model Splendor I have in my hometown never returned more than 65 kmpl even on highway rides.
My father used to get the carb tuned multiple times from the experts in town, changed air filter, tried changing the lock on the carb needle for a leaner mixture and better mileage etc.... But nothing worked and finally he gave up and is riding it happily for the past 5-6 years with a mileage of around 55 kmpl in city rides.

But for sure it is a reliable machine, have run 1.2 lakh kms so far, with a re-bore job at around 65k kms. One kick start, reliable electricals, long lasting clutch/chain, smooth gear shifts even with engine oil(be it any brand) that is 2-3k kms old etc. Reasons are many...

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

This is just a myth that old model were better as they only felt faster as they were lighter and that exhaust gave the feeling of more pick-up. Also old model splendor used 45T rear sprocket to Y2K 43T rear, so they pulled harder and nothing else. A old model splendor will feel it harder to cross 85 kph while Y2k will cross 95 kph easily.2001 splendor will return 60-65 kpl as all those models retained the same mileage due to their ignition timing and nothing else. In 2004 when splendor+ was launched people thought that it was a sticker job but the thing is that hero has cleverly changed the ignition timing so that the post 2004 model had mileage of 70+ kpl easily.The old model has different model CDI, y2k model has different with different part number and post 2004 model has same part number as y2K model CDI but has a S at the last part of the part number to indicate that it is for post 2004 models, with revised ignition modules.

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

I was following sibun bhai, couldn't believe how can a old bike's chrome parts shine so well. Then my eyes came to the tank and it was clear black. The color still had depth. It was a sparkling old bike.

I had a splendor earlier. I regret selling it now. This all happened after riding his bike.

His bike was super smooth like all new hero honda bikes. The thing I liked a lot was the way it pulled even when he said it requires some engine work to be done. Seriously my splendor never pulled like that.

My ride was short so can't give much report. But i can say that i had a smile after riding that bike.

I wish i met him before selling my 8 years old splendor.

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

Hello xbhpians..


This is my first post, got registered a week ago, was a observer of this forum from past few years
First of all hats-off to all Xbhpians, never seen such a forum where members share their hard earned knowledge just for free.


Now i am really looking forward to have good discussions with the xbhpians and meeting them.


Why i am in this thread? - Restoring my dad's CD-100. And i think this is the best place to get some advice.




About the bike:


Hero Honda CD 100, Mfg.Dt.Oct 1986, Reg.Dt. Jan 1987
The engine bears the name MADE IN JAPAN.
Distance clocked : nearly 2,00,000 kms
The price was around Rs:12,500, around 6 months of his salary at that time!!.


Was literally trouble free until year 2008 when the bike was not used for few months and it fell into some mechanics who did some bad job on it.


The mechanic charged Rs.5,500 and changed many parts in the engine,
we personally brought some original parts but not sure whether those are the ones which gone into it, by observing the condition of the bike now.
from 2008 it was sparely used, and now the condition is worse.
It couldn't pull even in 2nd gear with pillion during slight slopes and i have to slip the clutch.
The compression is gone, i couldn't feel the kickback any time during the kick start.
In cold morning it refuses to start and i have to push start it.
It stops in traffic during slowdown, the shocks are completely gone,
Was fed up with it, the bike was almost trouble free until 2008,
i decided to do complete restoration as i suspect some bad job on engine and suspension.


What i wanted to do:
Complete restoration, pull out all the parts one by one, check the condition of the parts with manual
and get get it properly changed/repaired with concerned specialist mechanics near my place(Hyderabad-Ram koti, Ranigunj)


What i did till now:
With help of my cousins pulled out most of the parts. i think i have to follow proper dis assembly(one after the other in a order).


I feel this restoration a bit risky because i am getting my hands dirty for the first time, before this i removed a spark plug, that's it.
Suggestions from my friends, CD-100 manual(thanks to shoeb), Xbhpians, and some basics of machines,
these are what gave me confidence to start this restoration.


I feel that its not right to just jump in and ask suggestions from you Xbhpians right away,
but i don't have choice and i am ready to share my learnngs also (if any).

Looking forward to some interesting discussions.

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

[MENTION=54652]smrutisourav[/MENTION]- Was great of you to share your experience here. In fact you are right the pull of this bike i miss in all bikes. All bikes will pull jerkily or you can feel the pull but on the joy the bike just pulls like butter and you cannot know until you see the speedometer. Moreover i thought you will not feel good of the bike as you ride a 200NS which have much power and feels a hoot to ride. Most of todays guys that includes my cousin brother feels that my Joy is a bicycle as they ride much better bikes. Even my brothers friends (he is 17) ride 200 NS, CBR 250 and all and when i pass by them or when i go to my brothers house on my joy they will be gossiping with him and they will pass comments and my cousin brother will also be a party with them. Some of the funny comments are:-1. Look at the BABA adam ka jamana bike.2. This bike has long been outdated from WW 2 era.3. Your brother is an officer in SBI and still ride that crap bike.There are many such comments. I never say anything just smile and think that you dumbheads what do you know about bikes. For you bikes means all show for impressing girls, ripping it day and night and looking cool and nothing else. This bike will still run the day when all you so called modern bikes will be in scrapyard and it will run better than new bikes at that time. [MENTION=66984]kathi[/MENTION]- Good to know that you are restoring your dads bike as few are there who really value the importance of old things. Good to know that you yourself is taking interest in restoring.First of all i would like to tell you that do a complete restoration rather than half hazard restoration.Get 5-6 big size cardboard cartoons for storing items. Mark them like engine, rear section, front section, body parts and store them after dismantling each and every nut bolt.Start with body first by coloring the colored part with only 2K paint and nothing else. For drum will advice you to change it rather than coloring. For front go for 130 mm drum from splendor, and rear stock size of 110 mm.Similarly for chromed items go for new rather than nickeling as nickeling is a waste of money and cost same as new. For wiring get wiring from MINDA or SWISS and change the complete wiring. Change the indicators, back light and headlight completely. Also change the meter console with original.For shock change the rear to new and overhaul the front one with new springs and oil seals.Overhaul the engine with new crank, new bore, new clutch and new timing kit.Rest for any specific query feel free to question here.@All- I had mentioned the bike was missing and showing starting problems a lot. Changed the excitor coil, cleaned the carb and tank of water and still the problem was solved. Finally my mechanic and i decided to check by changing the power coil and cdi and if also the stator plate. Since sunday was the family picnic left the bike near mechanic loaded with fuel for proper testing. I told him to change anything he wanted and couldn't be with him as i am proceeding for a picnic.He tested using new power coil and cdi but same problem. Before deciding on changing stator plate he decided to check the wiring near ignition lock and under tank as it had few cuts. Turned out that insulation of CDI trigger switch was cut and was leaking current onto ground. He properly re-insulated the cables and all problem vanished.I asked him if he has properly tested and his reply was the most amazing:- " I tested at 5 kph, 10 kph, 20 kph till all speeds and even ripped the bike till 100 kph".Man this bike is just indestructible as with this much of problem simple wiring was at fault. Also my crank was making noise and was thinking of overhauling the engine after crank eats up the bore as i like only to do a complete re-built but damn this bore is not wearing down and to add to it from past few days crank noise has reduced a lot. Bike still has very hard compression as [MENTION=54652]smrutisourav[/MENTION] can say how much hard the kick felt. On another note bike is approaching another milestone of 3.5 lacs kilometers or in other words- 3,50,000 km.

Splendor's CDI PIN OUT DIAGRAM





JOY'S CDI PINOUT DIAGRAM




Here is the link to files in PDF format. It contains much more information

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

I see you have almost stripped it down to the frame already . good job ! The frame is in excellent shape . Start by cleaning & degreasing it , removing rust and then use anti-rust primer ( murarka lead oxide primer ) in rusty areas and repaint with black enamel paint ( luxol Hi-gloss black ) . Just use a paint brush - no need for fine finish on the frame . Hand painting is more durable anyway - I feel . Before painting check if all the weld joints are solid yet ( looks like it ) or some weld spots are necessary . Check if the steering cone bearing's seats are ok or need work .
A good rust-free , strong and well aligned chassis or frame is the starting point for a good restoration .

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

Thanks for the link and diagram. Actually i have that pdf but was in desktop and not on my laptop. So the link will actually help a lot.Today i will take a printout and study the curves and then will reply as to what the differences are there in both the CDI timing and performance.And do not forget i will call you today evening.
