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

Before you do your next oil change , open the clutch-side crankcase cover and clean out the centrifugal filter (rotor filter for mechanics) . Most of your boric powder is likely to be accumulated there . If not , there is risk of a clog in the fine oil circulation passages of the engine . Are you trying to kill the motor ?

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

Is this part replaced by removing block-piston set?



Everything else in timing chain kit except this one was replaced yesterday by me.
What does this part do? Can this be called timing chain tensioner?

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

Is there a oil filter?
And I was noticing a hell of Clutch slippage before adding boric itself. After adding it, thats all, clutch looks like dead! Time to change the plates but BUDGET?!?

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

Clutch plate set and replacement cost are quite cheap , relatively . Take bike to nearby Hero ASC , should be around Rs 500.00 . While they are at it , ask them to clean out the rotor-filter and mesh-filter . These are the 2 oil filters there are and both are inside there . Cost would be i) clutch plates set ii) crankcase cover gasket (Rs25) iii) a bottle of hero oil iv) labour .

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

This is the oil pump sprocket. It can be accessed from the magneto side after removing the stator(coil) plate.
Timing chain tensioner and roller guide, all can be accessed from this side.

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

For unscrewing the oil pump sprocket, is it necessary to open oil pump as well?
I mean how to take it out (it is screwed well in oil pump shaft and it rotates freely when tried to open it by turning anticlockwise) after removing stator plate?

Re: Overhaul

Usually 4 stroke silencers do not clog with carbon. And since this bike didn't came with a CAT CON until 2010, so no chances of damaging.
The proof is in my video, you can see how hard the strokes and sound is in it, and that is longer silencer than your model. Also have run almost four times than your bike.

DO not cut open the silencer, else will sound horrible. If engine is burning oil then carbon will be in the silencer. The solution is to re-bore or change the bore and run lean, the silencer will burn the carbon and be clean on its own.

DO not remove the core as your bike will have practically no low end torque. Your model has already less low end torque as a result it runs 45 T sprocket from factory.

Recently i rode a 2010 model splendor+ which had cat con silencer. The engine is same as mine with minor changes, although it revs less quicker than mine and also sounds not like mine, but the low end torque is superb compared to mine. The bike just jumped when leaving the clutch.

The cat con increases the back pressure and thus more low end torque.

DO not remove the baffles.

Yeah why not. This engine can take anything that you throw at it.

Recently you read how i ran it on highway and i was mostly in 70-80 kph zone.

But be careful that oil is good as bad oil will cause engine to heat.

For opening the oil sprocket you have to hold the oil pump shaft from other end using a special tool by removing the oil pump from clutch side.

No need to open the engine. just have to open the clutch side, open the oil pump and use a special tool to hold the pump shaft.

But there is no need to change this sprocket. Rarely needs change as they never wear out as it has no load.

Yeah why not, can teach all and also point at what tuning and sound the mixture position is and what will its effects be on performance.

But presently my EGR valve of secondary air injection system is damaged, so you all cannot deduce from the video the changes in sound. Let me replace it and then will tell the difference in sound and will post a video.

Man you bored the engine spending Rs. 2100.

The new bore set for CD 100 cost Rs. 1650.

Post some photos of bikes.

From the looks of engine i can see it hasn't been maintained well.

There are remains of burnt oil on crankcases.

See the insides of my engine in the photo, and they you can know what i am indicating at.

Re: Overhaul

So, you suggest me not to touch silencer.
Then how to increase the sound?

Re: Overhaul

Sound not only depends on silencer. If the engine compression has gone down and the valves are worn then also sound will be less. Its simple, low compression low exhaust pressure and low bass in sound.

To get the sound back get the engine ready to new state. Then run it in perfect tune with a hotter plug like NGK CR6HSA, for 3-4 k kilometers and the sound will be back to new.

Else get a new silencer, the old shorter one cost Rs. 970.

But the quality of sheet metal will not be same as the old one.

Re: Overhaul

On the previous maintenance i was less aware as it overlooked by my Uncle... that i know it was burning engine oil for quite few years and ran little but 4K in last 3 years. So the Crank Case was black and brown with burnt oil and smoke (inside) which was not cleaned properly either not possible at the Mech who did the job.

And the people who done the job are less competent than i expected and somewhat negligent.

On the lathe work its a mix bag as they Send it to Vizag for rebore, with extra transportation cost, and did not send the head (valve) assembly .... the Crank Shaft has too much play and bearing got replaced so altogather

Rebore + Piston + Crank Shaft (bearing) + Transportation (150s) = 2000 Labour = 1000

Is that reasonable pricing !! But my choices are limited here as it far end of the state

SO that include both cylinder head and piston for 1650 !

I will go for a oil change at 400 km and lets see how the internal fairs

anyway took for a 70Km ride today and i can see slight white smoke when engine was pushed on 3rd gear for few seconds ( It should be noted that exhaust is filled with carbon and burnt fuel which might getting smoked)

will check the spark plug state on oil change



PS: Its on its 24th year of Service and every exposed metal to metal contact has huge amount of free play like center stand and back break rods
front suspension has little travel left. It has done its duty as fill and forget family wheeler for 15 years in its prime time than put on standby for last 10 years.

@sibun I went for Honda as i knew the technical expertise in Hero-Honda is of Honda, but as people perceive resale value of Hero-Honda was on higher side.
My family went for pleasure against my choice of Activa 7 years ago as they feel it looks heavy _) back than with non-plastic fairings ................. now most of which are broken in plastic Pleasure

Re: Overhaul



Replies in blue.

Re: Overhaul

Yep, Its taken its share of fall too and still a tough machine same original front Mud guard, crumpled and bent few times in past but just straighten and get go ... ha ha

I learn riding from this machine in the past. You are right....can't say same for plastic Honda though...

Thank you... i will see if we can arrange that in coming months

Don't we need to drain before 500Km after a re boring or new bore !

Quite right, but the Pleasure is the work horse now, and it has taken few fall by my mother and sis driving in the past (no bodily harm to anyone, thank god) but the metal guards along with the plastic body panel are goner, I removed those guards and fixed the panels here and there but they need full replacement in long run. Yes very well made engine. It runs with the ladies of the home so most trusted vehicle here.

I know, i have seen this machine work in last two decades, even i recommended my cousin who went for a passion in 2011 and running well

But in last 2 years Hero failing badly in quality control(In Service and Parts).. I have witness few recent Splendor that fail from their previous reputation within 6 months... much can be blamed for the poor service at Hero ASS than poorer parts though.

Ultimately every machine works as good as it serviced

Re: Overhaul

Yeah the draining of oil after 500 km is compulsory to follow.

And the splendors then let me tell you those who trust on SVC their bike is destined to DOOM.

Those buggers do not change engine oil, bill it and sell it outside. New guys just fiddle with bikes and uselessly do un-necessary works.

Parts quality is same or better, but these SVC mechanics damage the bikes.

I will tell detail in CBZ extreme thread have a look at it tommorrow. How those idiots have raped my bike literally.

We had a 2010 splendor+ which got stolen and now a 2013 splendor pro and both were and are running like beauty.

I never trust those SVC. Free servicing gone, to hell with warranty.

Re: Overhaul

I am buying some tools for the future on Saturday (again!) , so remind me a few things ... i) what size (number) and type (open, ring or combi) wrench is most suited for adjusting Splendor's tappet lock-nut ii) is the valve spring compressor a useful tool for Rs 150 ? Any other special tools used on this bike ? Pictures most appreciated please .

Re: Overhaul

#9/10 ring spanner or a combination one is good for adjusting tappet lock nut. Valve compressor tool is a nifty tool for 150/- but i have seen most mechanics use a big ring spanner and a screwdriver instead for compressing valve springs.
