Drippy Carbs seem to be part of ownership. Dave is original owner on his bike and after 10 year search I became 3rd owner of mine. They are pictured on this forum. Also own a 1979 KZ650 SR that drips, too. We replaced the gaskets and seals thinking the drip is from there, but it appears to be from where the hoses connect and if you reach in and dab the connections with a cloth you see evidence that the drip is happening there. Dave shot some cycle engine cleaner on the engine and wiped the mess off and it seemed to stop the dripping for a few months. Local Kawasaki dealer suggested carb replacement.
