1. check bowls for gas by removing a bowl OR opening drain screw. If no gas, then we can investigate why the bowls have no gas if there IS gas:
2. remove spark plug. Put the plug into the spark plug cap and hold it next to the engine and turn the engine over. Do you see a spark jump from the plug to engine? The plug needs to be a bit less than 1/8" away from the engine. If there is a spark and you had gas, then we will have to explore reasons why the bike doesn't start (separate line of troubleshooting starting with compression, etc) and if there is no spark, we will look at the ignition.

1) CheckHow are you going to make the carburetors flood? I doubt you can. To check to see if the carbs have fuel, either remove a bowl or open a a drain screw. I assume the bike is turning over when you push the starter button with the bike in neutral and the kill switch in the RUN position? If it turns over and the bike doesn't start:

2) Check.
Carbs are cleaned and no trash in fuel. Fuel is fresh. New coil, plug wires and plugs. The spark is a white to bright blue, plugs gapped to the correct specs. I have done nothing to the timing, but it is concievable something could have happend on its own (weird things happen around me a lot :silly: ).

I have done it many times to establish that fuel was getting through.
Although if it should pick that moment to backfire through the carbs, then a loss of arm hair will ensue
