Premature jubilation...

 Just when I thought I had exorcised all the demons, a new issue rears its ugly head.
Once I'd gotten the carb reinstalled and fine-tuned to perfection, I called it a day and thought there would be nothing but better days ahead. Then, a couple of days later, I went back outside to where she is parked and noticed a puddle beneath.
Off she came again, to verify the float and fuel levels...both spot on!
Then, I was able to give the drain screw another few degrees of closure, so I thought that was the issue. I left a bowl and hose setup overnight to capture any more wayward drops and sure enough...dry as the proverbial popcorn-fart the next morning. 
Guess I got it!

Three days later, I changed the oil and did some more wrenching and then put her away whilst I worked on Cheryl Tiegs.
After about an hour of tinkering, I look over to the TW and noticed another small puddle forming underneath again...WTF!?
This time, I noticed that I had left the fuel petcock ON...and the only way a carb will overflow when the fuel is left ON...is because the float valve/needle seat is leaking.

Ordered an OEM part from the local Yamaha shop (5LB-14390-00-00)
Now patiently waiting for it to show up. In the meantime, the fuel valve is OFF!
