What does leaving the choke on do?
Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. The engine needs its fuel to be vaporised in order to burn it. This is done by the carburettor where the fuel is mixed with clean air coming from the air filter, and sent into the pistons to be ignited.
How do you know if the choke is on?

Why does an engine only run on choke?
An internal combustion engine needs a precise mixture of fuel and air to run properly. When the engine is cold, it needs slightly more fuel in the fuel/air mixture for it to start, which is what the choke does. The choke increases the amount of fuel in the mixture, creating a richer mixture.
What to do if your dirt bike only runs on choke?
If the leak is on the air boot to carburetor connection, then tighten that clamp. This should fix it unless there is a crack in the air boot. If there is a crack, you will need to replace the air boot. If the leak is on the vacuum lines, then it is easiest to just replace the offending line.
