Hi,

I have bought Classic 350 from Velavan motors (Greams Road, Chennai) on November 2014.

Recently i have been hearing noise from my engine. So I took my vehicle to service centre, they are saying that there is some problem with Engine Bearing/Crank Shaft. And the service requires to dismantle the engine and will take a month and its going to cost me around 20, 000 rs.

I always service regularly between 3 to 4 months. My per day commute is only 20 kms. I dont go on long trips. I dont rash drive. At the maximum I drove is 80kmph. I dont know what I did wrong to deserve this.

Issues i have faced in my Classic 350 so far:

Amp Meter - They replaced with Bullet 350 (Black color) in warranty
Battery - I bought and replaced new battery, because the service center couldnt take my bike because of flood camp and the warranty has been expired.
Petrol Tank (Replaced by RE, Ticket number 160751)

Now Engine Bearing/Crank shaft.

Am I deliverd with faulty vehicle? Because I have seen people using 3, 4 decades old Royal enfield, but mine have engine problems in just 3 years. Did I pay 1, 40, 000 rs for a product thats going to last for only three years?

Even if it gets serviced, I dont know whether i can trust that there wont be other problems in future.
