I'm a little confused by your description of the problem, but if you mean that the starter is cranking the engine, but that the bike won't actually start and run, the first thing you need to do is make sure you have a fully charged battery.
It's not uncommon for a battery that is slightly run down to have enough juice to run the starter, but not enough to operate the ignition system. The spark plug won't fire and the engine won't start.
You changed the petcock ? Double check your work. Make sure fuel is getting to the carb.
