Your carb needs to be removed, disassembled and thoroughly cleaned. Then the "brass float valve seat" needs to be polished with metal polish! You will probably have to make your own "Q"-tip the old fashioned way!
There is NO overflow 'stand-pipe' in the float bowl like a toilet tank or dirt bike carb to deal with this kind of flooding on a KLR!
Modify at "YOUR OWN RISK"!
