Hey guys bought my first motorcycle yesterday. Noticed that there was a leak around the petcock. Turned it too off position... I wanna ask just in case. The shut off valve for the gas. How would I know if it is in the off position?but it appears to have stopped leaking. I'm used to working on cars so I'm fairly handy but I know a motorcycle is different! Any ideas on what it could be? Also the bike is a 1992 kawasaki vulcan 750. Thanks!!
