That depends on what you broke. My guess and only a guess is you may have damaged an O2 sensor but more information is needed.
Try spraying carb cleaner directly into carb to see if it fuel related.
You can either spray carb cleaner down the tube line that goes to it which is the metal tube next to the throttle plate. Or clean it thoroughly by taking of intake manifold which is a pain, taking AIC valve apart and spraying and cleaning it with carb cleaner!
The simplest way is to go to your local parts store, and buy a can of carb and choke cleaner. Start spraying this around the vacume lines, intake area, and manifolds. If there is a vacume leak, it will suck in the carb cleaner, and the engine RPM will change, and you might even be able to hear the engine stutter.
Try spraying some carb cleaner in the intake while someone cranks it over for you, if it continues to run, you have a fuel delivery problem. Possibly a fuel pump.
buy some carb cleaner... spay it at your intake and it shuld start. carb cleaner will not hurt the engin
spray carb cleaner in to intake while starting. if it wants to start, you have a fuel problem.
bad fuel pump, dirty injectors, vacuum leak
try spraying carb cleaner into carb and try to start if it fires then u have spark and comp then remove the covers one side at a time and spray with carb cleaner some time the screen gets a film on it
You can try cleaning it with carb cleaner by removing it and spraying carb cleaner into the port with the valve stem showing. That said, you may be better off replacing it as it is hard to properly clean it. There are some simply instructions for replacing it at Autoclinix.com.
Any auto parts store sells carb cleaner. If you don't have the skills to disassemble and reassemble your carb you may also want to run some injector cleaner through the gas tank. Also when spraying carb cleaner inside the carb make sure you have the engine running and spray slowly enough so you don't kill the engine. sometimes running the engine at fast idle helps. If it stalls and dies it can be a real bear to get it restarted. Good luck.
Carb cleaner doesn't really clean anything when you spray it down the throat of the carburater. The parts that need cleaning are the jets and internal lines. The only way to truly clean those parts is to remove the carbuater, disassemble it and clean the parts. Some carb cleaners can make a little difference if you run them through the tank, but spraying down the throat only gets a little surface carbon off, if that. -------------------------- The main reason to spray OTMAN carb cleaner at a carb while the bike is running to check for a vacuum leak. If you hear any change in the engine noise when you spray carb cleaner at the joint between the carb and the head, then you've got a vacuum leak. Get a new carb-to-head gasket.
Spray carb cleaner at the gasket. If you hear a change in engine noise or engine speed, you have what is called a vacuum leak.
