2007 kawasaki bayou 250 carb overflow tube leaks?

not a bayou but my ninja 250 over flow tube was leaking and i replaced te two o-rings on either side due to cracks and no more leaks. i had to get them from the dealer because i couldn't find them at a parts store. they were like 4.00 each but had to have them. the o-rings for the fuel rail i found at Orileys though.
