I purchased a bike apache 160 4v and bring it for my first service where they said there will be free service but they made a bill of 800 rs.
Don't like servicing of tvs.
Tell me where is the free service. Really hard to understand.
After bringing it back engine was giving smoke i don't know why. And it was giving ridiculous smell to like something is burning in engine.
