I’m a little confused here. You say you have cleaned out the carbs and the fuel injectors. Tell us a little more about your bike first, what year, model, carb OR fuel injection, you can’t have both!
Does it actually run or did it run before you carried out any work?
What do you mean by a buzzing sound? Which part of the engine/bike is it coming from?
How did you check the spark plugs?
A bit more detailed info may assist in helping you geting back in the seat again.
Just one further question. Do you have any/much experience of working on a motorcycle?!
