Gas Leak at Exhaust

Hello All. Gas is leaking from my right side exhaust at the cylinder when I start up the bike (cold start). Quite a bit comes out, but then stops. Bike runs fine. Doesn't appear to be any leakage into the crankcase as the transmission oil looks clean. Any thoughts?

I don't know unless fuel is leaking into that cylinder when parked. Are you using the vacuum petcock?

No, replaced it with a Pingel manual valve and try to run the carbs dry when I park it. Excess fuel must be leaking into the cylinder because both jugs are firing at start up. Now to figure out why.
