I just got a 1980 GN400 from a friend and it seems to only start when it wants to. I can start it sometimes with the fuelcock off and then turn the gas on once it starts. If I dont turn it on, it runs out of gas, of course, and then wont restart after I turn it on. Just looking for ideas of where to start since this is my first bike ever and I don't want to screw anything up.
Things I DO know:
It has gas.
It has a new air filter.
Could it be the Plug? Wire?
Any advice would be helpful. Thanks
