this is worse than playing 20 question....
we really do need way more info to help. so your saying since you crashed the bike with it running it blows fuel out of the air intakes on the front of the bike? and is this clicking while its running or while trying to start it, and did it do it before you swaped the carbs... what made you change carbs in the first place?
how does the bike run... good, bad, misses or what.
my only guess as of now is you have a dead intake valve that's blowing back up thur one of the carbs. but that's a really long shit and would run like shit... if it ran at all.
