Hero Moto Splendor/Joy/CD-Dawn/Passion

It’s a 2010 CD Deluxe. I don’t know when battery was changed last but the bike was starting with self start in just single press even last morning. Didn’t show any indicator of typical battery weakening. I will pull out the multimeter and test the volts tomorrow to confirm.

The luminosity has reduced on headlights and self start not working. Had to kick start today as well. Horn is inaudible or feeble too. Could be an alternator issue?

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

Check the connections. Also, how old is your battery? On an average a regularly used bike with a battery lasts some 2 to 3 years. Headlight should work without battery since it's powered by the magnet/alternator. Unless you have a DC CDI the luminosity of headlight shouldn't be affected. What model Deluxe do you have?

Hero Moto Splendor/Joy/CD-Dawn/Passion

Friends, need a help. Last night as I was riding on my CD Deluxe, rode through a patch of rough road (nothing big just small undulations) and the headlights went out.

So I stopped, turned off the light and on again, now it came up but with very feeble light. So I turn off the bike and realized that it’s just not the headlights that all battery connected accessories were either not working or working anemically - self start button, horn, turn lights, headlights, tail light, console light, fuel meter everything

I suspect that due to the rough road, the battery wire got loose or something? I believe the battery is still good as it was perfectly fine without issues until last night. Any other issues it could be?

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

Kick Starter slips in cold mornings. Is it indicating at a change of starting gear of Splendor ?

Or should a change of clutch & pressure plates should do the needful.

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

And the Uncles will continue to buy it. Looks like there's no real death for this wonderful engine.

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

Surprise, surprise. Hero has gone ahead and done it. The 1980's 100cc Honda supercub engine has been upgraded to BS6. Fuel injection with 10 sensors. Negligible powerdrop of some 0.3 ps. Hero motocorp is one unpredictable company. So both the legendary Splendor & India's national 100cc engine is here to stay.

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

Yes, true. I wish at times that I should have done it sooner than later.

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

Makino used in Splendor really works optimally as per its reputation.

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

To be completely honest, Bosch plates kept slipping when I first attempted to put them and ride on the Splendor when it was changed at 62K. Switched to OEM packed ones. Not the best around but they get the job done. Also, Makino ones the best from what I have heard.

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

Changed friction plates on the Splendor.





Surprisingly even the clutch center nut had regular threads, on my Puslar only the centrifugal filter has regular threads, the clutch center nut is reverse thread.

You need different special tools to remove both nuts, the center one can be removed with the Puslar type but the centrifugal filter if of a different size, we removed it using a rift and a hammer, Indian style.

And you really need the clutch holder to remove the center nut, jugads simply failed.

Friction plates from Bosch costs 100ish and OEM ones cost 300ish, we went for OEM ones.

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

Terrain are different for sure. Where do you live in Kerala? Loads are the reason why Hero bikes are geared short I guess, to gain good momentum. I think people will have a huge grin on their faces if they were ever to see the bike from which their engines have been sourced

I guess some bikes do last good for 3500kms but I think it's wise to drain earlier and be safe than sorry. The whole "if something isn't broke, why fix it" mentality is what lands our general motorcyclists in troubles over block seizures and all. Hero's machining quality has decreased ever since they broke the merger. I think's wise to drain early. My engine on Splendor got an overhaul (head cleanup, new valves; ODO read about 69,251kms). I've been careful enough to drain a bit early since the last two changes as my father has been using it for heavy density traffic commutes.

You are right about the part where surface area is better, hence flow is marginally easier. The better action of center of gravity is one of the reasons, cooling efficiency and besides they realised that it was high time to change that Cub engine. Besides the iSmart 110 mill retured 60-62ish on carb, so I assume it'll easily return 70+ on Fi.

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

My Passion Pro gives 65kpl in hilly roads of kerala. The roads and terrain in Odisha may be vastly different. These bikes are geared for carrying heavy loads. For a fact, the Honda supercub was designed to carry loads. These bikes are not much different. Other bikes may have better 0-60 performance but HH 100cc bikes have better load carrying power.

My father earlier had a Bajaj CT100. The bike was serviced ( oil change) at an interval of 3500-4000km. We used it for a good 95k km before selling it and it still used to give 75+ mileage. My uncles dream yuga gives min 70kpl under economy speeds & he changes oil at 3500km. I can't even dream of such oil change intervals on my Passion pro. I change oil at 2500km or else it becomes very rough.

Why did Hero adopt vertical design for their 110cc motor? In a press release Hero themselves said that the horizontal supercub engine has less cooling efficiency as the surface area exposed is less. So, they made a vertical unit to enhance the cooling and center of gravity. And engine cooling does determine the life of engine oil and fuel efficiency of the engine.

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

Lubrication efficiency yes, in terms of design and oil flow pathways. Load pulling? What gives you the that idea? Kindly explain. Efficiency and laws of friction don't apply to orientation or engine positioning; hence lubrication. The reason for low FE on newer Pro engines is because of the marginal increase in power over the old models (7.8 vs 8.36 on new models). Yes Hero did make changes to it post the Honda split. And the machining quality of parts is terrible. My Splendor gives an average of 65kmpl but on a good day I've got 72kmpl and even 79kmpl within the first 50k KMS of running. Now I get somewhere between 62 to 68kmpl.

All bikes require a 2500km oil change, depending on your traffic conditions, terrain & roads and riding style. While 2500 is considered an ideal ODO range, people drain earlier to ensure long engine life. I drain at 2200kms and at times earlier by checking the viscosity. I've not heard any Dream Yuga owner getting 70kmpl yet or Dream Neo for that fact. I've a lot of friend who use the 110cc Honda Motor's bikes (CD110, Livo, Neo & Yuga). 4000kms is possible only when you keep top-uping the oil at regular intervals and frankly, it's better to drain and refill than doing it.

1. Most likely not since it can't be made BS6. It's going be an expensive conversion and such a smaller engine doesn't make sense to be converted. Also, BS6 engines require high compression which the Cub Motor might not be good with.

2. As long as they want to milk more money from the bike, they will do it for the same of the Splendor name.

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

Its because of first mover advantage & lack of competition. In 1985 when the CD100 was launched, there was no other bike which was as fuel effiecient. Heck, the only other four stroke available at the time was the RE Bullet. For 5 long years, there was virtually no competiton for the HH CD100. Hence the name Hero Honda and the horizontal engine became etched in peoples mind as symbol of reliability and fuel efficiency. Although the Kawasaki Bajaj 4S Champion was launched in 1990, it was plagued with quality issues from day 1 (we had one). Then when the Splendor was launched in 1994 with a more sturdy frame and timeless look, the trust in this 100cc Cub engine was further cemented. Since then till now Hero has been shamelessly milking this engine.

The horizontal layout has slightly better lubrication efficiency. Also it has better load pulling characteristics compared to contemporary vertical engines. That's about it. These horizontal engines actually have less cooling efficiency than vertical ones. That's a reason for lower FE and low engine oil life in HH 100cc's. My Passion Pro gives max 65 kpl and engine oil lasts only 2500 km. Whereas a CT100, Platina or Honda Dream Yuga gives minimum 70 kpl and engine oil lasts for a good 4000+km in them. But then, they don't have highway performance like my Passion Pro either .

Now, 2 questions decide the future of Hero Motocorp.

1. Will they update the 100c Cub engine or get rid of it?

2 Would they change the design of the original Splendor Plus or keep it untouched?

Knowing Hero, they can be very unpredictable. They created superb designs like Splendor, Karizma, old Glamour, Maestro Edge, Xpulse 200 etc. On the other hand they create and also ruin some of their best designs like 2014 Karizma twins, Achiever, Xtreme, Ismart 110, Splendor pro update, new passionX pro, duet, Xtreme 200, new Glamour etc. Hope they take a well thought decision this time!
