Thanks bro [emoji106]

Re: TVS Jupiter Owners Review and Experience

The plug looks fine in the pic bro. No soot, no white coating. The AFR is ok.
Also spark plugs last 30k kms on an average (50K if its iridium), so there was no need for replacing it on a new scoot.
As I said, please try filling petrol from a different station and see if that changes anything. I can't figure out any other problem in the vehicle.
Do keep us updated after trying out the new petrol pump.
Ride safe brother.

Re: TVS Jupiter Owners Review and Experience

I've changed the plug, kindly check it.

Re: TVS Jupiter Owners Review and Experience

Bro, I'm running out of ideas on what might be wrong.

One last thing that you can do is, change the petrol pump. There might be a chance that the petrol is not of good quality.
Try filling up from a different station and see if that makes any difference. A new engine should not do that and you have checked everything else. So lets change the fuel for a few weeks and see if it resolves the random shutting down.

Re: TVS Jupiter Owners Review and Experience

Hi , again i faced the issue, i went to svc and they tuned the afr, but again today i faced the issue of scooter turning off while climbing down a speed breaker. I did engage choke in the morning for 1 minutes, and then idled it for 10 minutes even then the scooter turned off, my odo is 2600 kilometers only, the svc also adjusted the idle.

Re: TVS Jupiter Owners Review and Experience

It won't probably won't. Speedo units usually cost 2-3k+ probably. Digital speedo that important to you?

Re: TVS Jupiter Owners Review and Experience

Hii guys,
I am thinking to swap speedometer unit of new Jupiter Grande to the the standard Jupiter.
The shape of new speedometer and old one is almost similar.
The only problem is that how odometer and speedometer works in digital unit as there is no speedometer cable in front wheel.

Re: TVS Jupiter Owners Review and Experience

I did DIY successfully.[emoji2]

Re: TVS Jupiter Owners Review and Experience

The asc people tend to fiddle with the idle screw unnecessarily. The AF screw may get nudged because of that. It's 1 and 1/2- 3/4 quarter turn for jupiter. Open the box cover in the storage and do it if you are comfortable. Sometimes a minor turn in idle rpm is all that may be required.

Re: TVS Jupiter Owners Review and Experience

That's brand new brother.
So we can rule out the clogged up air filter, faulty spark plug and choke left on by mistake.
The only possible cause that I see is improper air to fuel ratio. Take it to the service center and let them know the problem, they will tune up the air in 2 mins and give it back to you. Since the scoot is practically brand new, they won't even charge you for it.

see if that solves the problem. If not let them know when you take it for the next service. I would advise you not to take it to a local mech yet, as they might mess it up even more.

Re: TVS Jupiter Owners Review and Experience

My odo reading is 2200 kilometers only, 2nd servicing done. I face problem in morning only, i close choke after 40 seconds in morning.

Re: TVS Jupiter Owners Review and Experience

How many kms, has the scooter run and when was the last time the Air filter was replaced?
A choked up air filter might cause shut downs. the service centers have fixed kms after which they change the air filter, before that, they clean the filter with pressurized air and fit it back. But if you live in particularly dust place the life of the air filter will reduce significantly and you will have to replace it early. open it up and check its condition, then decide.

The next up would be air to fuel ratio, most of the time, if you complain that the scoot is not giving mileage, the service center guys make the ratio a bit lean to which might be the reason of engine shut down.

The most unlikely reason might be spark plug gone bad. It is highly unlikely, because the spark plugs fitted from factory are such good quality that they easily last 50 thousand kms without any problems, but if nothing works out, open the spark plug and check its condition, it might have gone bad, due to wrong air fuel mixture.

And last but not the least, make sure that you turn off the choke after warming up the engine, riding with choke on will give you same problem and will use more fuel.

Re: TVS Jupiter Owners Review and Experience

Hi guys, i am facing a problem, whenever i slow down the scooter in speed breakers the scooter turns off, I've set the idle rpm such that the tyre rotates slowly while idling on main stand, i warm up the scooter for about 5 minutes every morning. The problem mainly occurs in morning, even after warming up the scooter, is there any afr problem. Please help.

Re: TVS Jupiter Owners Review and Experience

Appreciate the replies.

Re: TVS Jupiter Owners Review and Experience

I used the same TVS tru4 oil for engine and transmission on my Jupiter. Changed before 3K kms. Scooter was touch wood even as 48K kms Odo. Now I am thinking to do some Synthetic oil experiment on Ntorq,s engine. But will use the Mineral oil for transmision.
