07 vulcan classic custom LT. I have had it a short time but seems the speedo is showing me I am running slower than what the gauge is showing. There seems to be 1/2 tank left when showing empty. How many miles do I have left when the gas light is light? Wife and I are both very uncomfortable with the stock seat. Any ideas as too a better ride besides spending alot of money on a new seat? And final question, what should I expect for gas milage? Thanks in advance for the info.
