Ok, I just went out today and hooked my bike up to a portable battery box and tried to start it. All lights work and gauges seem to be functioning. I go to try and start it and all it does is crank but no actual starting. The bike sat for a year so I'm not sure how to coax it into starting again. The oil light came on so I know I need to add some oil to the case. Also I noticed that one of the carbs bowls had fuel leaking from a screw on the side of its bowl it was only one bowl screw that was doing it any suggestion as to why that happened. I went out and bought some seafoam but I don't know how to use it as a starter fluid I need help from you guys
