I want to rebuild my carburetors my bike has been sitting for about six years. Does anyone know a good kit to buy with the gaskets. I just want to clean everything up inside and not replace too much unless you think I would have to .
Usually, you can find K&L parts on fleabay. Probably all you need are the needle and seats. However, if the carbs are CV carbs, the rubber diaphragms could be leaking. I would buy a weld tip cleaner for cleaning the tiny passages in the carbs. what model Vulcan do you have?
Turn over fully and start fully are two different things. Will it crank strong? (turn over) or not start to run? (fully start). I am going to guess that it is cranking due to the new battery. Not starting would then be no spark or no/ bad fuel. If you have spark, drain the tank add new fuel and try again. Even with new fuel if the carbs are dirty or plugged due to old/ bad fuel. They would need to be cleaned. Also remember that if it has sat for a long time the fuel will have evaporated out of the carbs and you will have to crank for an extended time for the vacuum petcock to open and fill the carbs. If you have a prime position on the petcock you can use that to fill the carbs.
