My classic 350CC is 4 days old. I have experienced an issue that I am riding the bike the engine cuts out. The fuel tank has close to 6 liters of fuel and set the fuel knob to ON. I immediately changed the fuel knob to Reserve and the bike started running as usual without any problems. Then I changed the fuel knob to ON and bike started working for say 2 to 3 KMs and then bike started to stop. I had to immediately move the fuel knob to Reserve for it work.
Anyone that can give me any advice on what to do?
