I have a problem with my Honda unicorn the bike. The bike starts but the moment I accelerate the engine stops. In the rainy season, this gets worst. Some time during travel if I change the gears the moment I leave the clutch the engine stops and jump-starts. The service center does not seem to have an answer to the problem. I have tried changing the spark plug, cleaning the tank, cleaning the carburetor, changing the diaphragm in the carburetor. Engine de-carb. Nothing seams to work. The worst thing is the problem is not consistent. Does not happen all the time, which makes me look like a fool at the service center.

Can any one advice.
