What will happen if for a bike, i open my tank lid and then turn on the bike? ?

Nothing, will happen unless you have too much fuel in the tank, then under certain conditions you run the risk of the fuel coming up out of the filler cap area-but that is very rare.

the bike will fire off like normal. When a bike gets vapor locked, and someone calls it is what I tell them to do. then close the lid and ride over so I can fix the problem.
