Even though it's kind of a PITA on the Vulcan, I recommend you go ahead and remove, disassemble, and clean the carbs to begin with. They are probably filthy inside. That should be a one time thing, use of Seafoam in the future should keep them clean. Sounds like your Vulcan my need quite a bit of maintenance. Definitely do the spline lube before riding it, and hopefully it is not already too late.
A drop in gas mileage of 4-5 mpg on a 454 means serious trouble. It's either leaking somewhere, or running really rich. I have a Ford pickup with a 390 four barrel, and it averages around 10 mpg in town, but I am NOT a conservative driver, my main hobby besides motorcycles is drag racing. Jerry.
