Last 2 weeks while driving in night I bumped my honda activa 3g scooty in potholes an ups and down almost like 4 to 5 times and now since then.In the morning while going to work when I start it and accelerate to et going it makes shuddering sound and the same when I accelerate it after giving a brake and the speed is nearly zero.Today infact while riding(after having accelerated it and riding it) I hear a gargling sound in low amounts almost as though my scooty is quite old.
My scooty is just 10 months old.Im the 2nd owner so for me it's only 3 months.

Please tell me what all repairing I need and approx cost
