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

On long rides there is deposit of wet and dry carbon soot but I asked some mechanics they carbon is due to faulty petrol and they told reduce in engine oil is normal due to heat

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

Exhaust is to be checked at shutdown engine, not revving etc.

Are the deposits on Exhaust end Dry or Wet on touching?

Check bolts, washers, O-rings for pin-pointing any leakages.

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

Little bit of carbon deposits are Thier on high rpm but no smoke is there

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

Nice update.

Would definitely follow.

Thanks

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

Due to regular wear and tear I've now brought my change interval down to 1.5k km's.

Especially since a fellow xBhpian has a R15 that has clocked 1.6L on stock internals and he follows 1.5k oil changes.

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

Please first check the insides of Exhaust tip with clean cloth wrapped on little finger.

There should not be wet carbon deposit.

It there is wet deposit of Carbon , then rings should be changed, preferably 0.25 size rings should be fitted with hand grinding.

It its clean with no deposit of Carbon, then look below and sides of engine for answers (leakage from bolts or O-ring/s).

My bike Is new bs4 splendor 18000kms done piston rings cannot go so early

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

Hi,
1.
Instead of changing the Rubber Ring, (original being good one with unparalleled quality, hence retained)
I took it out.
Put an old rejected tube of my bike and got a Gasket cut from it , of similar size.
First put this gasket on Tank Cap,
then the original Rubber Ring upside down.
This will make the Tank Cap pretty snugly fitting !

This cured my Evaporation Problem from Tank Cap in Splendor.

2.
My O-ring on Carb was leaking Petrol.
To cure it, Bought an original O-ring of the Stator Plate Assembly.
Used a new Razor Blade to cut it to size required to snugly fit in the Float Chamber groove for the O-Ring.
It was fitted back.

Now, after both these, the Petrol smell near Tank is gone,

regards

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

The splendor has made me question myself about my bike maintenance ethics and the quality of recent Hero bikes.

An uncle in my neighbourhood has a 2004 splendor plus. He is the type that considers a motorcycle just as an appliance, no emotional attachment whatsoever.

The daily routine of the uncle is like every morning 7.30 take the bike out, hop-on, one or two kicks ( it usually starts at the second kick ) and just when it starts put the first gear and go.

There is no concept of engine warm up. He never washes or lubes the bike himself. Gives it for servicing to the local mech once in every 3000km or so. Never bothered about which oil brand or grade is put in the bike. And gives it for pressure washing once in every 2 months.

I was really surprised to find that the bike has done 1.2L km even with stock clutch plates and was consistently returning 70kmpl.

Now on the other side, I wash my bike almost every weekend, warm up the engine at least for a minute and used to change engine oil meticulously every 2000-2500 km.

Once when my bike was 81k old, I changed the oil to semi- synth castrol power1 15w40.

Somewhere I read that SS oils can last longer and I decided to extend the oil change interval upto 4000 km.

First 4k km were great. Much better throttle response and slightly better FE. So obviously again I bought castrol power1.

There was a 100 ml drop in oil level which I noticed but did not mind as I thought it was normal. During the second 4k km, the bike started to lose pickup, sometimes it felt like the piston is going to seize. Oil level dropped like crazy and that was it.

My passion pro died at 89k on the odo and I had to go for a bore piston change.

Now the thing is that an old almost neglected splendor plus is still running like new with all the fibre panels intact while my well looked after Passion pro has all its fibre panels ( side and tail ) broken/cracked just by going through potholes and also required a bore kit change at 90k.

So it seems that Hero has really decreased parts quality since 2010/BS3 era.

I also learnt that no matter what kind of oil mineral ,SS or FS, if its an air cooled engine it will last only till max 3000km. And I learnt it the hard way

By the way now I use only mineral oil and drain it every 2000km as I used to earlier.

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

Seems like the piston rings are faulty. My passion pro had the same problem but I had to change the bore-kit as is had slightly scored due to really low oil level.

Check and top up oil frequently.

Just change the piston rings by a good local mech and dont go to the ASC.

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

Guys .. please advise.

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

Hello everyone I came across one problem ii n my bike the engine oil is decreasing by 80 to 100 ml every 1000 kms is it okay or is thier any problem in my bike no smoke from exhaust once I got 680 ml after drain in 2000kms help me

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

Does anyone know how tall (or wide) the gears are out of the factory for a 2010 CD Deluxe?

I acquired one recently from a relative and as I had no experience with similar 100cc motorcycles before and was trying how the gears are setup. It’s surprising that even 4th gear works on speed breakers some times with half clutch. I know it’s not good for the engine and was only trying out to see what’s the lowest 4th gear can go.

I also shift up pretty early generally in motorcycle and cars and this motorcycle seem to be made for me with me with me being on 4th gear in no time at all.

Is this normal for these bikes or it has become like this because of previous usage?

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

The Splendor is a complete motorcycle, no BS like the front lifting under load or hard acceleration, it runs without any compromises.

A friend owns a 2010 Splendor and the things can haul ass like no other even after clocking 1.5L on the stock cylinder, within Kerala roads I can't keep up with him on my CT100B due to the Splendors superior roll-on acceleration, the guy can and has run circles around me.

But at the same time a while ago I had gone on an interstate run with another friend who owns a more recent Splendor with self start 2013 I guess, the thing refuses to cross 80kmph on the interstate, has only 55k on the odo, while my CT100B can scream on the interstate at speedo indicated speeds nearing the 120kmph mark(100kmph true speed measured with Sigma cyclocomputer).



Payload was similar as I'm heavy(About 120kgs) and carrying everyones luggage whereas the Splendor was hauling 2 rider. We couldn't try the other way around as the CT100B handles like a pit-bike, front goes up when accelerating hard with a pillion whereas the Splendor rides like a true motorcycle no BS or drama.

We didn't check FE then but on an earlier instance where I'd rode at WOT for the better part of 8k km's on the GQ circuit the CT100B returned a FE of over 60kmpl as the fuel expense was between 8~9k, don't recall the exact figures but when riding within Kerala my FE seems to drop hard to about 50kmpl mostly due to riding style and short stroke nature of engine whereas the Splendor maintains consistent FE when ridden on our challenging roads, the earlier mentioned Splendor with about 1.5L km's returns over 60Kmpl when ridden on the MC route shuttling between TVM and Adoor and you know how irritating the traffic conditions can be on that route.

Splendors seem to be the only model that is immune to the year end price drop due to demand, back in 2017 when I was urgently looking for a commuter as my Wego developed a cracked chassis after a bad wreck Venad Motors quoted 10~15k discounts on the Splendor Classic for previous year makes, I would've gone for it but the exchange rate on the Wego was way too low and that meant I'd have to shell out money I didn't have at the time, so went over to Sarathy Bajaj and they were kind enough to offer exchange value of the IDV of the Wego as it was TL anyways, hence making it possible for me to go home with the CT100B.

Though to this day I'd still say that if money wasn't an issue I'd be on a Splendor Classic instead of the CT100B, plus the lack of a rear seat on the Classic was something I was looking forward to.
