TVS Motor Company — Tvs apache 200 4v bike, engine problem

Address: 411057

I have buyed tvs apache 200 4v bike in november of 2016. Some problems occurred after 1 or 2 months regarding engine. Now, it is about 7 months, still there are a lot problems in engine. After receiving bad experience at the service center, that is no solution to many problems. Now i am tired of all these things, so i wanted to change the engine of my bike so it will help me further.
