I have a 2005 hyosung gv250. Im a bit confused about. Some of the hose from the gas tank and carb. When I was taking out my gas tank my return hose I believe it is. The one directly under the gas tank wasn't connected to anyting and the hose connected to the left side of the bike on the double carbs that turns into one hose was also not connected. Is it supposed to b? Im still really new at this but I fixed my carbs and got my bike to finally run again. I just don't want to leave 2 what could b major hose undone.
