I have bought hero glamour on 4th May 2016 every thing regarding the bike is fine but since my 3rd free service my bike is showing troubles. While travelling at a speed of 30 kmph in city in front of traffic when I slowing by pressing clutch, brake and gearing down my bike suddenly stops i.e. the engine kills while the clutch is in pressed state and also it is not giving adequate mileage. I showed it to the mechanic they said there is a problem with tuning they looked over it but 7 days later again my bike engine stops suddenly. I want to know what is reason for this trouble... is there dirt in oil supply line or improper carburetor adjustment.. please provide me advice how to solve the issue?
Please help.
I didn't find the right solution from the Internet.
