Hi Ali amir, thank you for your reply. I want to know something that is related to bikes. So recently I have noticed that I do get enough milage from my bike. It was one month before that I got 40 kilo per litre but out of no where recently I realised that it dropped down to 25 kilo. I do not know what made it happen, it is being a very serious problem to me. I own a Suzuki Gixer 150 cc single cylinder bike. I like in Bangladesh, here any 150 cc bikes goes at least 35 to 40 kilo per litre of octane. I do not have any idea what did I do wrong. Being a women it is very tough for me to go to local mechanic vendors. They also make false complains and force me to change parts which are nit even damaged. That is why I am posting this in here. If you guys just tell me which part of my bike is damaged I will just tell them to make that particular change so that do not have any say or make me change something that do not require a change. Please help me out. What can be reason that suddenly my bike is not responding to fuel. Is it wasting my fuel ? or just there is leak that may have causing this issue.
