I have a 2013 Vulcan classic 900 which I bought last year. I'm fairly new to riding. Two days ago I was riding and had gone about 40km/30miles and the bike just shut down. At first I thought I stalled it. I put in N and tried to start and I heard the starter engaging but bike would not turn over. I waited about an hour while waiting for a tow and decided to try again. The bike started. I cancelled the tow and resume riding getting within 15 km home when the bike stopped again. Wouldn't restart so was towed home. Any thoughts very much appreciated. Thank you.
