After sitting in storage for a couple years I cranked up the bike and gas started dripping. At first I was thinking sticky float. I lifted up the tank and could see gas coming out around one of the two T's that connect between the carbs. So I removed the carbs to poke around and found inside the float bowl is super clean with no gunk and needle looks good. I am suspecting the O rings on that supply T. Maybe just 24 years and shrinkage. Not wanting to separate the carbs but I'm pretty sure it's required. Any thoughts?

 

Nope, no way to replace those O-rings without separating carbs. Sitting for couple years guarantees carbs need complete disassembly for restoration work anyway.
