I have had a persistent fuel leak that I have been trying fix on my bike.  I replaced the fuel line from the petcock to the inlet on the carbs and put some clamps on the ends of the line.  That fixed the small leak.  

I took it out for a ride and ran great.  It did have a little hesitation above 5500rpms though. When I got home I discovered another fuel leak.  This one is leaking from the overflow line on the #2 carb.  I'm guessing the float is stuck.  It wasn't doing this when I put it away for the winter.  I am going to run some sea-foam in the gas just because I think it could probably use it anyway and maybe this will help.

I'm also going to try tapping on the fuel bowl with a hammer handle or something similar. Should I run the carbs dry when I do this?  Should I have the bike running with the carbs under demand?  How hard should I tap on it?

If I need to remove the fuel bowl can I do that with the carb still on the bike? Is this going to require me to re-sync everything?  I don't think it would but I don't want to open a huge can of worms.
