Is it possible to dismantle float-bowl only.Instead of removing the entire set from the bike ...

If you look closely - the foot rest assembly will not allow you to remove the cover because it is obstructing it. SO,one needs to loosen the foot rest bolts(#17) to lower it slightly.
As soon as I find some time,I will take some pictures of my spare CD 100 engine and post a comprehensive procedure here.
I am having some scrap iron rods,let me see if I can weld it to make a holder out of that.

Nope, I've removed my clutch cover without loosing the footrest bolt. Yes it obstruct a bit but you can be manage to take out, even mechanics didn't ever loose the footrest.
Pinaki ji is correct.

At least I was never able to do so,if you guys are able to do that then its great.
I think it is even mentioned in the owner's manual that the silencer needs to be removed to loosen the foot rest bolts.

Not tried by myself yet , as you know last time I had the HeroHonda ASC clean my rotary filter on paid service . They took out only 2 things - the clutch cable & the kick-lever . Then unbolted that cover . They were using thin sockets attached to those pneumatic drivers that you see them using on all the nuts and bolts at the service stands . One difference is that my silencer is not same type as yours (alas!) - it's the current ugly black powder coated one with separate chromed heat-shield .... maybe it allows more space there .
Owner's manual also says that only the clutch-cable and kick-lever needs to be taken off for clutch cover removal ....




Why , is that holder thingy quite expensive ?


It will work , but less than 50kms - that oil is a light cleaner-cum-lubricant (has kerosene in it, you can smell that) . The consistency is similar to WD40 & Zorrik . You can use ordinary motor oil instead , works much better - even used and drained motor oil will do (although fresh oil is to be preferred) . Motorcycle drive chain experiences considerable shock-load and needs a heavy lube . HeroHonda recommends sae 80 or 90 gear oil , which is of same weight as straight(non multigrade) sae 40 motor oils .

Yes , very well so . You just need a suitable (very short) phillips screwdriver . Infact that's what they do for carb-cleaning at the HeroHonda ASC . Then they unscrew the jets and blow it hard with their compressed air hoses and fits everything back on . They clean the float bowl itself same way after unscrewing the drain screw out . But they never take out the float/float-pin or any other parts .

You can use adjustable screw driver which can move from 180 degree to 90 degree angle.
just for an example (this is not adjustable)

But my manual says different. but still i can remove without removing or loosing it.

Elementary , my dear Watson ! That means - they have positively made some change to either the footrest assembly or the muffler (or both) since (mine is July 2010 model) that allows that , that's why they made the necessary change to the owner's manual instructions too . This can't be just a printing error , it's too nicely done .

I think there is slight difference in the clutch cover/muffler/foot rest which allows the cover to be removed easily. Any way we now know what all thing need to removed if clutch cover is not coming off easily.
Other thing I noticed that my centrifugal was almost looking clean and brand new,last time I opened it I could not find even a tiny metal shaving.
Apart from the centrifugal filter ,the design of the filter mesh placement and oil passage is just excellent.
Oil passes thorough it in both direction hence cleaning it effectively.
First - All the oil to oil pump goes through the mesh.(Regular usage)
Other way -When oil is drained from engine,all the oil flows from the opposite direction which almost cleans filter mesh.(During Oil change)

One word of caution to anyone cleaning the engine internals and covers- Please use a lint free cloth always,I found some lint stuck to the filter mesh when I opened it on Sunday.

This bike is just excellent in all aspects and probably this is the reason it continues to be the worlds largest selling bike even in today's severe competition.

EDIT:
Pinaki Ji,Do you remember our discussion on carb float heights ?
I found that if these floats go out of specification then it must be replaced - As Simple as that.
If the float-pin mating surface/seat gets damaged then whole carb body must be replaced and other parts like jets can be re-used.(I wonder if only body is available.)

Source- Just got hold of a Unicorn service manual(pdf),if any one needs that please let me know.

lol when i said that its printing mistake
....i know company do changes from time to time therefore instructions too. I was just trying to show u, & may one benefit it and nothing else.

By the way, i would like to see if there is any new thing added on the maintenance caption of your manual book.
here is mine, you know my book is printed in 2003


How did u fine a name Watson for me??

Do u guys think my head inlet pipe o-ring has gone?



I replaced recently with an original one, and part number was 100% correct. Replaced so many times with OE, but couldnt understand if it really leaks or its normal
I saw dust stuck to that area everytime.
Its annoying me!

I never followed that schedule,these bike can take a lot of abuse and still run perfectly. I just listen to what the bike tells me and I do the needful. On the day I got the keys,I promised my splendor to giver her timely oil changes. Apart from the engine oil--air filter,chain,carburetor etc needs periodic cleaning as you know.
Nowadays I am lubing the chain with a mixture of Diesel engine oil and 140 gear oil every week end. Chain seems to be clean a lot longer with this mixture,please try it out.
I am using a cheap local 140 gear oil which is used generally in the rear differential of heavy truck, costs just Rs 20 per 100ml pouch/packet.

@ Paul
Here you are - excuse the poor quality , I seem to have misplaced my tripod-to-camera attachment ryt now .



Dr Watson was assistant and biographer to the famous detective Sherlock Holmes , in the novels by Sir Arthur Conan Doyle . Holmes used to say that (Elementary! my dear Watson) to Dr Watson whenever they would arrive at a meaningful conclusion of the detective work by examining all the aspects of a case and pursuit . I am much addicted to all the Sherlock-Holmes novels since my schooldays . You did good detective work and clarified the difference between the two manuals and model-types for me ... now it is all clear to me .

note : Although "Elementary, my dear Watson" is perhaps Holmes's best-known catch phrase, he never uses exactly those words in any of the books written by A. Conan Doyle.

Yes , the bike is very simple but excellent design . Even mechanics love to work on Splendors . Easy to work on by oneself too as I am learning now . I have comparatively much much difficult experience on my friend's wind-125 , horrible parts availability , crude parts and design and all non-standard(japanese industrial sized) nuts and fasteners .
Yes , many have tried and failed against this 97cc tiddler .. even Honda's new strong competition ( Dream Yuga , is better in most aspects like acceleration & torque etc ) is not selling well here against this age old model yet . Funny thing is that this bike's design & puny engine is taken from the famous Honda-CUB/Honda Trail-90 & Trail-110 , the original Honda designed bike that makes them the world leader today - and Honda gave it away to Hero Cycles here once for royalty .
Yes , I told you that too , this float has no mechanism for adjustment - contrary to my Crux's and the Wind-125's which I also service . In place where they have a metal tang which can be bend to adjust the float height , this Keihin's float has a a solidly affixed plastic tang - preset at factory (which is obvious from those blue stencil marks on it) . This is an example of an adjustable float tang , that metallic thingy bend up or down makes the float height higher or lower (and consequently the fuel level also) inside the float bowl .



And you can see the white plastic tang in the middle of our carb's float there - and because the body metal & hinge pin posts are relatively soft aluminum and the float hinge pins is hard steel - I knew it has to be replaced if damaged or scored so I used a wooden toothpick to push it out gently ...




Yeah - I needum unicorn manual - for both my Cbz-X and brother-in-laws new unicorn .

Good , shall try it - am in the lookout for alternative to Castrol GL4 gear oil - it's costing Rs 120 for 500ml now .

@ Detective Mr Pinaki
Sir your pic quality is fine & readable.
I can see suspension on page 42....if it is for back then leave it coz i've non-adjustable rear shocker.
What is that catalytic converter & air suction valve on page 47 ?? something new to me, would like to see both.
and what is that so called Engine oil top up process??

Thanks in advance.

Edit:
Which camera do u have? Set white balance to the auto mode.

Do u know if separate tool bag is available in OE? lol

@bloggingwheels- Usha machine oil is thin which is completely useless. Chains are like gearbox which acts under extreme pressure. That is why the gear oil are graded in EP grade. Usha machine oil are almost similar to zorrick or WD 40 and they are essentially de-greaser. So using them on chains is not recommended. Use SAE 90 or EP 90 oil. Buy a 1/2 liter pack and it is good for more than 1 year. Lube every 1000 km. In-fact on using gear oil chain lube can be extended till 1500 km and chain will still be not dry.
@paul- Nothing to worry about the dust. This is normal. If the o-ring would have gone then the bike will be taking air and causing problem. Why are you opening the intake manifold so much time. In my joy the intake manifold has not been opened from factory. That o-ring doesn't gets damaged. The dust is normal since air is passing over it to cool the engine dust settles on it due to obstruction to air flow. So do not fiddle with the intake manifold.
@shoeb and pinaki- The new model muffler(black cat con) is redesigned and foot peg a little lower so that clutch cover can be opened in 5 mins flat. This has been incorporated to easy the service of bike. The old model like splendor/passion/cd-dawn/joy all requires the silencer and footrest to be opened. Even if the silencer and footrest if not opened, then slight loosening of the footrest bolt so that footrest hangs down is sufficient.

Also regarding the float chamber, no need to fiddle with the adjustment. In my old carburettor the carburettor was changed after almost 11 years but still there was no need to adjust it. The float is available and also the float pin. By the way the pin cost Rs.145. And no the throttle body is not separately available.You have to buy the whole carburettor. Regarding jets and needle that is another thing which i have to explain in another post.

By the way if your float is not stopping petrol then no need to change carb body. There is easier work around for it.
For this use valve grinding paste. Apply a slight fine grinding paste on the tip of ear bud. Now insert it into the place where float pin rest and polish. Do this and check if the surface is polished. Also while polishing use petrol to wet the ear bud which will ensure the grinding past remains wet. After the surface is polished take out the bud clean the paste using petrol clean the carb.
This is the common method that my mechanic does for those carb which leaks petrol from float pin seat.
And regarding this engine, then not only the engine but many thing like the chassis, body, switches, locks everything is still UN-matched by any bike.
and this bike can run so much that no dream yuga,no boxer, no discover any thing can run.

Proof is my joy.yesterday it completed 3.20 lacs and still it runs like the day it came from factory. The list of things that came from factory is more than some bikes like three years old. The bike has following things from factory and still running like new:-
Wheel bearings, handle,rims,all levers, main stand, every body item, gearbox, head, gear shifter, almost everything except bore-piston,clutch, connecting rod(crank is same), valves and rockers(valve guide are same from factory).
So you can see why this bike is so popular and still competitor cannot touch it.This is the ultimate of honda technology and HERO engineering and quality which makes it un-beatable.

@ Bike Guru (Sibun)
Few years ago that was leaking therefore opened it to change. This time I opened at the time of De-carbonize.
Anyway,
I want to use a single gear lever, i mean just a front one, i use very often a back one for shifting gears. So wanted to change, can u tell me for which bike i should go for? I want to go for NON-OE brand.

I'll keep this lever in a safe place, so that, if ever i want i can switch back to the factory one.

Edit:
Some people say that u can shift gears without using clutch but some are against of it and says u should use clutch.
I want to know if this really doesn't create any problem? Do u DE-accelerate while shifting gears??
I've the habit of using clutch every time, right from the day i got my bike.
