Where do stay ?

Toll Free No. 1800 266 0018.

Describe the entire sequence that happened at the ASC. I am sure they will help you.

You are supposed to get this work done under repair warranty as they have charged you for full engine overhaul and messed it up badly.
If hero customer care does not help then we are here to help you.
Carry out the repair as soon as possible and in the mean time keep a sharp eye on the oil level. Don't let it fall below the min mark or you may risk damaging crank and other parts.
If they are going to charge you for the parts other then gaskets and consumables then just don't do it.

Problem and solution in brief.
This thing was expected because the piston was removed from bore to replace the crankcase and they re-used piston rings which are not sealing now as its position has been changed.
What you can do is remove the head and bore. Install the old rings and measure the ring end gap. If it looks normal then lightly hone the cylinder, install new rings and re-use the bore and piston.
If the end gap is excess or if there are scratches in the bore then re-bore it to first oversize and use USHA pistons.
Polish the valves and clean the head thoroughly as I am sure the ASC has not cleaned it.
After installing everything back, adjust the tappets .

What ever I have mentioned above is not in detail. Call hero and let us know what they have to say and then we will let you know what needs to be done further.
Don't worry, your bike will be back in shape with least expenditure. Sibun and other members are here to help you out.

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

Sir,
At last I had got a thread where I can share my problems and expect a solution. I stay in kolkata & had enough communication with Mr. Pinaki (thanks bro) regarding selection of engine oil. However I belong to yesteryears and not very freindly with the use of computers.
Now coming to the point...........I own a Splendor NXG (self start & alloy) from 2011. Till date I had clogged 22500km in my odo. A few days back my engine suddenly stalled in the middle of the road. The compression had totally gone down to zero. From my previous experience of riding Enfield 350 for the last 27 years I immediately understood that the problem is with the valves. Finding no other alternative at late sunday night, I purchased a pouch of 2T oil from a petrol pump and added in my fuel tank. The engine came back to life almost immediately & since then running till date. I had talked with the ASC people they said that the pair of valves needs to be replaced.Then I took opinion from a local mechanic (who was previously attached with Bajaj ASC). He took a ride & advised as followed.
1)Since 2T oil is added in fuel the valves must be replaced.
2)For the same reason Piston Rings needs to be changed (Although no smoke from exhaust).
3)After doing the above two changes the engine will return to its initial position & the clutch will be mismatched therefore the clutch plates would also need to be replaced.

My old trusted enfield mechanic is telling me to continue driving the vehicle by adding 2T oil in fuel at the ratio 2ml per litre petrol until the exhaust starts smoking, this problem is with almost all persons riding new generation small bikes.
I am totally confused to take any decision . Requesting all splendor owners to share their experience over this issue.

Thanks to all of you in advance.

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

I can tell from my experience with my Passion + that adding oil in petrol has not solved the issue but cooling down of engine has.
Was the engine very hot ? Any tappet adjustment or any kind of work done in the past few weeks ?

It happened to my passion+, the tappets were set incorrectly, fuel was adulterated(this bike was mainly used in rural areas).
The end result was burnt valves, heavy gum deposition on intake valve and whitish stuff on exhaust valve. The lower side of the valve stem was looking out of shape and was not allowing free movement in the valve guide.
Head was removed, valves were replaced & seats were polished, carburetor, intake port,head and piston top was cleaned thoroughly,tappets were adjusted correctly.

Stop using 2T oil and start using System G to clean the deposits. If it does not solve the problem then do as I mentioned above.
No need to replace piston, rings ,clutch etc.
Just remove the head, inspect valves and replace as necessary with genuine USHA valves, inspect valve guides, clean the carburetor, intake and exhaust ports and most importantly clean the exhaust as it has a catcon which might have been clogged up due to the usage of 2t oil. Replace the engine oil as it might be contaminated.

Sibun should explain it much better than me so please wait for his reply.

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

In another automobile community site i read about mixing acetone with petrol.is that really helpul in getting xtra bhp , mileage..etc?

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

Simply u can check the plug rating at your bike owner's manual. Go for NGK (first preference) second MICO, and don't think about any third one. Buy from any outside shop, better go to Authorized dealer to buy original. If u went to Hero service center, most probably you won't be getting the same rating and most likely u won't be allowed to check before u buy.

Yes i heard that too, but anyone here didn't tested that. However, we would love to hear something new in this thread from your side if you gonna buy pure 500ml acetone for Rs.300 for testing purpose ..just think about it!! for 300 one can buy about 4 liter of fuel, then who will buy that high cost acetone.

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

The problem is that i don't know where it is available . Can we use the nail polish remover. heard that it is also acetone

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

Thanks for your advise. Waiting for Mr. Sibun's comments...................

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

@ harish_gkumar - acetone is available at shops that sell laboratory instruments and chemicals to school and college labs . There is got to be one like that in you town , possibly in the bookstores street . I got a 500ml bottle for around ₹ 125 . Yes nail polish remover (elco) and nail polish thinner (elco) is the same stuff , costlier ones like revlon contains impurities like colour & perfume etc . It is very flamable and dissolves paint in a second other than being a potent carcinogen . Be careful in handling it .

I would advise you not to mix it in petrol or anything on your bike , unless you are feeling really reckless . If you are , pm our dear PSR for more advise on it .

If you are looking for a good fuel additive , give Iftex System G or System 23 a try .

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


By adding 2T you have just moved the problem further but not solved it. adding 2T is actually harmful as it will cause deposits in inlet and exhaust track and also will cause deposits on valve and head.

There is no need of touching the rings,piston and clutch. Just open the head clean the head of carbon, check the valves for bent or pitting on surface and change that. Properly polish the valves and fit bank. For tappet adjustment there is a simple procedure even no need of feeler gauge. Just while adjusting tappets ensure that there should be no vertical play in tappets and there should be as much side play as possible. Or in other words the rocker arms should be loose enough so that they can be moved sideways but tight enough to have no vertical play.

In a matter of Rs.600 -700 your bike will run like new.

But valve leakage in splendor is rare as i have never heard about it. It will be because of improper valve adjustment which will be causing it.

Acetone is quite harmful than useful. Why do you want to add it. If it would have been so wouldn't the company recommend it. If you are so interested in using additives use system G as :-

BMW Intake Valve Deposit Control Test
Ford Intake Valve & Combustion Chamber Deposit Control Test
Chrysler Port Fuel Injector Cleanliness Test
Honda Generator Test
GM Intake Valve, Combustion Chamber & ORI Test.

Guys have you seen the new hero website it has a new blog, customer feedback, service booking, test ride, and vehicle registration, have a look. Overall hero is trying to increase its customer trust and is waiting for new products to be launched.

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

Sibunji,
A ton of thanks for your valuable advise. However I want to purchase the valves personally myself, can you please advise the part no of the same. At kolkata we had only official outlet to purchase Hero Honda original spares i.e. Bansal Motors or I should go for purchasing any other brands please advise. Mr. Pinaki you are from kolkata please advise.............................Thanks a lot again to all of you.

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

Firstly , no need to yell - I am here and reading your posts from begining already . Please update your location , how else would I know you are from kolkata . Also please do not quote an earlier post un-necessarily , we already know what you are referring to .

Original OEM parts are available at Bansal motors in wellington , you are right , they are the authorised Hero distributor for bengal . You can purchase Usha brand valves also from other shops in wellington . Guddu'jee (9836530716) stocks USHA and OE hero parts in his shop near Bansdroni market in south kolkata .

But before all this buying , find a good mechanic . Dismantle the engine head and clean it up . Then check which parts need changing . Then buy .

Unless you have been using 2T oil in high proportion for a longer time ( like months ) no serious damage have occured . Revert to neat petrol and use a cleaning additive like iftex-system-G ( 1ml per liter of petrol ) and run like that for sometime and see .

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

Nitrogen filling bogus trick
What they claim is that the pressure remains constant for 2 months.But actually
the pressure loss is noraml as air.Even with new tyre and tube
What they do here is that they fill more than recommended inorder to maintain
inflation levels normal .ie they raise upto (30 psi f and 40 psi rear).It gives us bouncy ride and discomfort..

Benefits
One benefit is that the tyre remains cooler in long drives and will not increse as normal air
Other one is that Inside of the tyre remains dry.. in nnormal air we can see come sort of water content..

I didnot find any major benefits from my last one month use.switching back to normal air which is free

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

Guys, Need a bit of advice. A friend of mine has a splendor+. His bike has done aproximately 1,10,000 kms. After his free and paid servicings were done he used to depend on a local mech for maintainance.

A week ago his bike started loosing power and went almost dead.. His mech had been taking money from him every 2 months or so for repairs. When i got the engine opened at home we found the whole engine screwed up with wrong o-rings, damaged oil seals and what not.

Currently the whole valve train along with rockers and tappets would have to be changed. All bearings have been changed, clutch has been rebuilt, crank has been rebuilt with skf bearings.

The problem is his piston has seized. Its on 2nd os. My mech tells me it is better to go for a new block than going for a 3rd os. He says over boring the splendor to 3rd os might cause problems with efficiency and tuning. Is it true?

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

You are in cuttack, so go to usha dealer which is in cuttack and get a new bore kit of splendor from him of usha make. If any problem you can bring the splendor to bhubaneswar and show it to my mechanic.

3RD oversize is not recommended and fuel efficiency will go below 60 kpl.
