Don't ride hard. Since the engine is all with new components, it needs to be properly lubricated and also has to set.

In a plain road don't ride in constant speed for long. Just very your speed until the run-in process.

Start slow, idle for 1-2 min early morning.
Avoid hard braking and acceleration.

Rest assured you can find run in procedure almost in every thread.

RohIIT is correct.

Also please go through the user manual provided by Hero. Somewhere they will be mentioning about the Runin procedure.

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

Yes i will post tomorrow because right now i am in office and bike is with my brother at home. This is the first time i am riding splendor more than one(1)km.it is smooth and i maintained speed between 40-50kmph.
The mechanic who gives delivery of the bikes (new one).is dumb and he always ride all the bikes at full throttle and also says that hard riding makes engine set properly. Also advise everyone to do this till first service.But i all ready mention that please don't give full throttle while standstill. I have just maintained speed under 50kmph.

+1 to that. Here also when I was taking delivery of my bike the guys were driving like crazy when they took for waterwash and back.

And regarding run in follow what Rohit sir and Prashanth sir have said. Also go through user manual. Make sure you have got everything necessary with the bike. Like toolkit and first aid kit and all accessories for which you have paid.

Congrats for the purchase. Wish you many happy miles on it. Post some pics of the bike.

From my experience what I have found was, splendors need 20,000 kms to set in properly. After that, you can feel the real smoothness and the awesome ride quality.

For now, as everyone said, maintain the speeds within the economy range.

Happy riding.

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

So much posts. I am finding it difficult whom to answers and what!.

Well glad that this thread is active like before, the mecca of bikes knowledge.

3. Yes maybe it is also.
4. This shouldnt be because forks have never leaked and bike has ran just 3300 kms.

Me and my father would go to the svc tomorrow for service. The wobbling is just close to negligible to I think I would tell the svc when it becomes more problematic. I will update once it gets serviced. Also I will ask them not to change the engine oil because I want to use Veedol 10w30. By the time the bike would get serviced, I would go and search for the oil. Lets see what happens.

The tyre is not that old. The bike has ran 3300 kms.

Thanks prashanth sir and satson sir.

Its the tyre. Usually it happens and you can do nothing of it. It will occur at a particular speed. It will decrease after tyre wears down a little more. So wait and watch.

5th Service Update:

We reached the svc at 11:00 got the job card made by 11:15 and bike was sent for waterwash. There were no major issues with the bike except the headlamp's focus was so poor so we got this enetered in job card. We asked about not changing the engine oil but he said that its mandatory and cant be ignored. We also agreed due to warranty issues.

The bike was loaded at the service bay at 11:45. The service engineer was an experienced one. He changed the engine oil, cleaned air filter, gapped spark plug, adjusted and lubricated chain, lubricated side and main stand, greased clutch and front brake levers, cleaned the air filter box, inspected all the electricals of the bike, tightened brakes, inspected clutch and throttle freeplay, tightened some bolts and filled nitrogen.

He told us that the headlamp bulb has gone kaput and thats why the beam throw was so poor. He said that it needs replacment. So we got the bulb replaced.

The bike was done with servicing at 01:00 and polish was left. The bill came out to be Rs.455 : 285 for engine oil, 40 for nitrogen and 130 for bulb. They said the bulb is not covered in warranty. Got the bike at 01:15 with polish done.

I am satisfied with the service. One can not expect more with free service. The svc people were also very helpful. They answered all our queries.

Glad that you are satisfied with the service. I don't remember the free services on joy as i was small then but during extreme i used to go a small svc. There only one mechanic was allowed to work on my bike. He did all the services. I used to tip him handsomely. He took care of all things and even used veedol 10 W 30 that i took.

I was allowed to be with the bike while servicing. Even the washing boy was not allowed to wash the bike and my mechanic used to wash the bike. Sadly the mechanic left the svc and i also stopped going to svc.

After so many failed attempts to tune the carb and find the correct tuning, now I think that this time I have got the correct tuning. I followed what sibun sir and pinaki sir said. I got the carb and jets cleaned. And after that I decided to use the trial and error method of tuning the carb like jeswin sir did. Now after 100 kms of continuing the same tune here are the plug pics. But still I am not sure how is the mix. I want to ask the experts. Please tell whether this is optimal tune or not.

Plug: Bosch U4A
Bike: Hero Passion Pro

Thanks.

The plug shows your tuning is almost correct.
Ride for some more and the oiliness and carbon will burn to give a correct color.

And since your bike was running with excessive rich mixture, your exhaust port and silencer will be full of carbon. Run it in this tuning and the carbon will burn up. For better results ass Addon satchet in petrol available at indian oil petrol pump. Once it clears up the bike will feel more better to rev and smoother to ride.

ThankU Sibun

What for man?

Now a days people thanks me for no reason and also scold me for no reason.

No need of another pic. Get OE plug not aftermarket. OE comes with resistor.
Trial & error method is more difficult than normal tuning. Most people do get the higher rpm while tuning however get stuck and confuse where, at what point, to leave that air screw. Thats because at that higher rpm point about 1/8 range will be like same rpm, no increase or decrease. And that's why most people find it difficult to tune and the results doesn't get what they actually need.

Now the question is how to get perfect tune. There are few key points that YOU must UNDERSTAND and FOLLOW.

The place of tuning: You must tune in a quite place where there is absolutely very less background noises and all you can here is only your bike rpm with deep concentration. And there should be no one to distract your concentration in listening to rpm.

Patience: This is vitally important to have patience while you tune. It takes almost 10-15 minutes of concentration while tuning and most people want the result in 2-3 minutes which is NOT possible therefore they give up saying 'I can't do this'. And that's the reason why they fail while they tune because they might be thinking 'someone is watching them and laughing what this guy is doing'. Because of this another thought in mind they can't focus on what they are doing, and they end up with thought 'I can't do this!' -personal experience.

You have to give up that all. While you tune sit comfortable and feel comfortable. Makesure there is no such thing in your bike which would rattle with the vibration because that sound will mixup with sound which you want to hear. Keep aside your tools.

Now, hold the leg guard and keep you eyes stick in the utility box (thats what i do) and see its frequency of vibration.

At that 1/8 gap you will find one point where the vibration will be in an uneven pattern. We need the equal pattern of the vibration, where the up and down frequency will be exactly same. We need the same pattern of frequency, the vibration.

You need to use your 3 sanctuary factors out of 5. Those are: touch, see and hear.
Now touch the leg guard and feel the vibration. Don't focus on that part much. What most important is what you hear and see.
Hear the sound very very closely. You must able to create an image, a picture in the screen of your mind of the flow, the pattern of the vibration and it should be same, not uneven.
See closely your utility box vibrating and you will notice the difference.
Dont make a change in air screw too frequently. Hold on to that for 30-60 secs before you make a change or you are sure about that this is not the correct point.
Move back & forth the air screw very very lightly and notice the changes.
REMEMBER changes in rpm doesn't reflect instantly, you must give a time before you can notice the change and moving ahead altering the air screw.
When you look at the utility box closely you will find the vibrating pattern. Hold on to that area and keep altering the air screw before you can see the equal pattern in the vibration.

Read this twice, thrice and understand what i am trying to say. What i have wrote now is i have gained thru my own experience with multiple attempts (may be 15-20 attempts or more) of trying to get the best results. You can't get it at 1 or 2 attempts, that's what most people want and fail. You must give yourself enough time, don't see the clock running. Follow the above advise and when you're done with tuning, drive your bike for 2-3 days before you can check your mileage and plug because bike takes time to adjust itself, to get habituated of the change in the new AFR.
@sibun i hope i have able to make this understandable to the people upto your understanding level?

Bhai a big bow to you. Made it understand a lot simpler way. And you will say and people will not understand. Its not possible.

Bhai tu toh mera guru ho gaya.

Good to know that. Always maintain the bike in mint condition. It will never let you down. Read Paul sir's post several times and understand it clearly before tuning.Check the mileage for atleast 500 kms for now. After that, you can decide whether to tune further or not. I'm scared to touch the fuel screw any day

Did you use the wax which you have bought? After experimenting @Pinaki sir's post and @sibun sir's post regarding the wax, I found something. I bought motomax liquid polish and Formula 1 car wax. The cloth which was used for polishing the bike with Motomax liquid polish turned from yellow colour to black colour. It removes considerable amount of paint for sure. So, stopped using it.

I tried the same with Formula 1 wax. The colour of the cloth did not change.

Then i took some motomax liquid in between my thumb and forefinger and rubbed it. I felt some grain like particles in the fingers. The same feeling was there with Formula wax also. I thought that I was imagining and so I took some Colgate gel tooth paste and did the same. It was smooth and I did not feel any grainy particles. I concluded that the particles were abrasives. So, make sure that the wax has not got any abrasives.

Members correct me if I'm wrong.

Wax and polish are different things. A polish will always have abrasives. It will polish the paint to bring out the shine.

But wax will always be soft. It will only coat the existing shiny layer with a layer of protection film so that your paint doesn't face the vagaries of nature.

To detect it you have to do the following tests. Just take a pinch and rub in between fingers. If it feels rough then its not wax and contains abrasives. Its as simple as that.

Paul sir, please explain why non resistor plug can never be light brown/tan? I am asking this because it definitely appears light brown to me. Maybe in the pic it is blurred.

And regarding OE plug, some members here suggested that there is no harm in using non resistor plug?

I have gone through your post about tuning and read it many times. I will surely do it.

It not resistor or non resistor, its with heat range. Our bikes original recommended is PRZ7HC and CR7HSA plug. If we compare that to mico it should come to heat range 5. But the part number is UR4A. So its a colder plug.

Ngk has stopped CR7HSA and is now giving CR6HSA which is a hotter plug. For the ngk plug you will get white plug for correct tuning. The rationale behind CR6HSA is that old model activa, pleasure and all use the same plug. So its a matter of one size fits all.

The plug photo i posted is of champion and it has correct heat rating.

Also if you notice mico plug the electrode is little flush while NGK and champion has a little projected center electrode. It has the advantage that flame projection is faster and engine feels responsive.
Negative is that if little oil or improper mixture then the plug will sort quickly.

So I can continue using that plug as of now? I cant go to the svc nowdays. If I would have known this just 2 days before, then I would have bought the OE plug because I was at svc for service.

Indeed, that is a very rare colour to find in spark plugs.

Yes colours differ in resistor and non resistor plugs.

Thank you.

Yes it indeed is a rare color as my bike is also rare. I am also rare.

Been through some rough days..... Life is full of ups and downs.... Anyways..... Pinaki da as your Ignition coil showed 4kΩ and mine is showing 7.39kΩ, it is quite clear mine has almost doubled. Inline with spark plug and plug cap yours is 8kΩ in total. Mine is 7.39kΩ ignition coil + 5kΩ of the plug cap =12.39kΩ Total. I think that clears the picture a bit .... That is why I saw improvement when i switched to non resistor spark plug. So I think the ignition coil is the culprit why i had to clean the spark plug so frequently.
Since last time when I got bad mileage (hope you guys remember the incident) and found out my Air screw was almost screwed in. I took my bike to a stranded place (coz I live in an apartment) and tuned my bike and since then I have been getting 72 - 75 kmlp mileage and I didnt had to open the spark plug to clean the carbon deposit for past one month. Though the AFR was almost perfect, one thing I like to share is that i have kept the air screw half turn out. I didnt do it intentionally but this was the best and optimal setting I got. Did the tuning according to Sibun Sir's guide. The mileage , throttle response and spark plug everything was perfect at this point but the only concern was that the air screw was only half turn out. I was thinking at that point that it was due to clogged jets and once I clean the carb I will also be able to set the air screw 1.5 turn out as everybody here is always saying that 1.5 turn out is a good starting point for tuning the carb.

Couple of weeks ago i got the Air screw O-ring and yesterday I cleaned the carb thoroughly and put in the new O-ring (old O-ring was almost flattened). Cleaned every screw and hole. But when I again re-tuned my carb the most optimal setting I can find is the same half turn out. Anything more then that leads to slow throttle response or rmp comes back to normal in slow motion. Am I doing something wrong or am I having a unique bike lolzzz .. Dont know if mechanic has ever swapped my jets or not . I found out No.105 and No.38 jet in my carb while cleaning. Is this half turn setting a thing of concern or should I just forget it and enjoy 70+kmpl mileage and be a happy person.
One thing I forgot to tell you guys that when I completely tighten the air screw the engine does not die, It still stays on. I thought cutting the air completely should kill the motor but surprisingly it stays on. And when I am on half turn out the engine do not die even if I fully unscrew the rpm/throttle screw. Cant understand whats going on with my carb.

Thank you Sibun sir. If you havnt told me about the o-ring it would have not got changed.

Check the air screw tip. See if it has small grooves cut into it or the tip is worn. That explains your setting at half turn. Once my joy was running at 0.25 turns from full tight. And that setting was for 2 years or almost 60000 kms. After i changed the air screw that problem was gone.

And for your ignition coil resistance clean the ignition coil terminals and check. If resistance is still high then change the ignition coil. Go for Power brand. It is costlier than OE and is also better than OE.

Congratulations for the splendor. Long time that someone bought in this thread.

Pictures man, although its the largest selling bike still we are searching new splendor photos in this forum. Sadly no one.

photos please and some thoughts on what made you buy it and also how it feels.

As for run in follow these till 1000 kms:-

1st gear- 0-15 kph
2nd gear- 10- 25 kph
3rd gear- 20-40 kph
4th gear- 30- 60 kph.

Then you can increase by 10 kph in 3rd gear and 4th gear after every 1000 kms.

3rd gear will pull till 70 kph and 4th gear till 100 kph. But for that you have to wait till 5000 kms.

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

One little query for one of my friend. He also has Passion Pro 2012 model and has clocked about 22k on it. Now the self start has started to give him trouble. When the starter is pressed, the bike makes a clicking sound but does not produce any sound of engine starting. But it starts in one kick. After driving some kms and stopping and then starting from self, the bike starts. In short, mostly it makes a clicking sound and very rarely starts with self.

His battery seems to be okay to me. All electricals (horn, light, indicators) working fine. I told him that its related to starter relay and he might have to get it replaced.

So I want to ask is this problem related to relay or some other things? Also how to diagnose that battery has gone kaput?

Thanks.

First thing that you should do when riding the bike from the showroom is, go to a fuel station, fill petrol and check the tyre pressure.

If I am correct, the manual says 28 psi and 32 psi for front and rear respectively.

My bike runs on highway most of the time. So I keep 32 psi and 38 psi in front and rear tyres respectively.

That's too high. Irrespective of city/highway, maintain close to recommended pressures only.

It is okay if you keep 3 to 5 psi more than the manual recommendation. Even if your tube looses some air over time - still you will be running under good psi ratio.

More than 5psi is not advisable because of the following reasons:
1. We will get bumpy ride
2. Especially in summer the air will expand and chances of blowing our tubes

I think you are running with a good psi level...

I usually fill with my bicycle pump. Font I will maintain between 26-30 psi and in rear it will more than 32psi but less than 40psi...
