I picked up this set of carbs with a bunch of Yamaha XS650 stuff, my research leads me to believe they're off of a GS450; I'm not a Suzuki guy so please chime in if you have more info.... Anyway, I've no use for them, but was rebuilding another set of Mikuni BS38s for the Yamaha, so I stripped this set down and rebuilt them while I was at it.
-Fully torn down, fully cleaned, all passages blown out and clear
-Diaphragms are in great shape with ZERO damage/cracks/holes/flaws
-All brass/jets are stock OEM Suzuki

-Mixture screw emission plugs have been removed
-Brand new throttle shaft seals
-Butterfly screws have been replaced with stainless allen head bolts, secured with blue loctite
-Throttle shafts, slides, and choke circuits all move freely and easily
$250 shipped within the lower 48
I'll get pics up tomorrow, thanks
Sorry man, there arent too many GS450's around here. Mostly GS500 owners. And GS500 carbs are an upgrade to the GS450 stockers anyway.
Might want to try the GSResources.
