I gave my new TVS Jupiter classic for 1st service. Immediately after service, I am getting tick tick soundafter the ignition is stopped. Do you think the dealer has tampered with my new scooter as this tick ticksound was not coming before the first service

For this, we would suggest you to visit the authorized service center as they will inspect the scooter and will help you to resolve it. You can check the service center details here.

If this tick tik sound remains for some time only then the should not be any problem. This sound could be due to the BSVI compliant catalytic converter in the silencer which is normal.
