I purchased a Hero Achiever 150.
Bike had many issues in it like not accelerating over 7000RPM while riding, which was complained and sorted out in 2nd servicing. Then suddenly while riding bike to my village, bike stopped moving anymore and its piston was destroyed. The reason for that was no engine oil in the engine, caused due to the negligence of the mechanic at the service center for giving me the bike without proper checkup while 2nd servicing. I claimed warranty and all the damaged engine parts were replaced as the service center says and they have only changed bore and piston.
Ever since then my bike was not the same. I had to go to service center once a month having lot of issues in it, and engine used to drink engine oil pretty fastly than recommended. I had to replace engine oil every once in a month. Engine used to emit white smoke all the time.
I think there is something worse happened to the engine due to driving it without oil and the service center people are not disclosing and trying to escape from getting loss, but just managing me and the bike to work temporarily.
I have given a proper complaint with notice in it to the company to repair my bike permanently to avoid further correspondence the service centre people kept my bike with then since 11 days and today is 12th day I haven't even got it back from them yet.
What could have happened to my bike's engine? How will I be able to check if it's okay after I receive it from them without warranty being void? Because I hardly know about bike engine and they might fool me again.
