The plugs in the front cylinder are clean so I swapped them for the rear, which are the ones covered in gas (I cleaned them before reinstalling). I had the same problem. After running for 30second I rechecked the rear plugs and found that they were covered in unburnt fuel again.
The bike was running beautifully earlier today... and I had the carbs resynced about 2k miles ago. If it is a stuck float, is that something that I can access without pulling the carb off? It's been a long time since I've opened up a carb, so my memory is a little fuzzy....
(Also, added bike details to my signature)
