Tvs Motor Company — tvs jupiter vibration and tak sound?

I own a tvs jupiter for last 3 year. I have vibration problem in front of the scooter. Mainly it is the clutch. Tvs mechanics have changed some parts of the clutch and the problem still exists. I am sick of visiting tvs service centre again and again.. I want you to help me with this. The scooter is not running smooth and ever time during pick up and braking this vibration comes in front at the footrest. The vibration is so much that it even makes noise. Help me!
