Re: TVS Jupiter or something else?

Dear Srini,
Thanks for your quick response. During first incidence, I changed the sparkplug. But still it was not starting, though old plugf was clean & good.
when kick starting I dont see any hard resistance or restraint

1- Did you try opening the Fuel tank lid and closing, maybe there is an airlock that's happening and choking the engine from getting the fuel.
2- Does the scooter have a side stand engine cut off switch, pardon my poor knowledge on scooters, asking since my Activa 125 has one.

Thanks for the response.
Yes one of my good friend(Somnath) told me the same, i.e. open the fuel lid & close it. That did not work too.
side stand - no such switch wired to to ignition etc.

Further-
While kicking- Do you feel the kicker going down freely or
While using the starter- Do you "Hear" the starter sounding as if it is turning freely?

During Kick Start, Kicker is normal, neither to hard nor too free. Its the same as it was in new scooter.
Starter sounds is also normal. yes due to this problem, the battery drained and starting was somewhat different; but after charging the battery, it is now sounding normal
.
Thanks for you response.
I was suspecting some electrical wiring issue or some other issue but TVS dealer says, if that being the case, the system shouldnt be running at all.

Battery drain indicates a leak in the circuit. So i would check the entire circuit including the connectors for any kind of shorting or grounding. The carb of the Jupiter has an over throttle protection switch. If that switch is open then the connection between the ignition coils and the plug is broken and there would be no ignition.

I am not sure if your vehicle has a led light inside the under seat storage area. If so please check if it is on, even when you close the seat. I verified my wife's Zest by placing mobile with camera running inside and found that led does not goes off even after seat is firmly closed. So removed the led light and now everything is good.

Negative. No such LED lights are installed below the seat.

Maybe the tappet clearance is not within spec. Could you ask the service guys to check and adjust the tappets?

In my opinion, this is not an electrical/voltage drop related problem. More to do with the something going out of spec on heating and returning to spec on cooling.

Re: TVS Jupiter or something else?

Hello. I ride a 2013 TVS Jupiter and my in-laws have a 2019 TVS Jupiter. After riding their scooter, I felt it to be twitchy/unstable in the handling department. It is something like when I am riding in a straight line, the scooter doesn't go in a straight line and I have to constantly give small corrections to keep going in a straight line. Can there be any particular reason for this or something which needs to be checked. My wife also feels the same when riding the newer Jupiter.

Could this be related to alignment by any chance? I have observed slight misalignment between front and rear tyres of motorcycles driving in front of me.

Have a look at other causes in a discussion following post 101 on page 7 of this thread by member para_7k.

Re: TVS Jupiter or something else?

Has anyone retro installed a front wind shield on the old jupiter ( not the jupiter classic). I need to install this as I take my kid for nearby runabouts ( I usually take him in my car where I can belt him in the rear seat) and I feel a windshield can have some protection against direct wind to his face .

I ordered one from Amazon, need to visit my mechanic once it arrives.

Re: TVS Jupiter or something else?

Sorry Mods, I could not find the appropriate thread. Please shift to the correct thread.

My query is regarding Jupiter tyres.

I have a 2018 Jupiter Classic for which I want to change tyres. The stock tyre size is 90/90/R12 both front and rear. I find the stock tyre size low on grip and thereby confidence.

I would like to upgrade to the Ntorq tyres which is 100/80/R12 front and 110/80/R12 rear.

Can experts please let me know the pros and cons?

Thanks.
