hello i have an 1989 suzuki katana 600.it has 4 into 1 yosh pipe and clamp on filters.also was re-jetted.the bike has sat with fuel in it for 6 years and now when i added fuel it leaks onto ground.i removed carbs checked jets they seem to be clean but 1 fuel valve had a groove worn into it.would this cause an overflow to all 4 carbs?when i removed filters they were soaked with fuel also.bike runs but runs like crap until u reach 6000 rpm then it runs great.


any info would be appreciated
