Hello there! So today i was trying to start my bike for the first time this year, but it's not working. It's a Suzuki gs500e (carburated). I checked the spark plugs(they are new), they do spark, cleaned them, put them back in; btw, before the winter I filled up over 12l of gas(so the tank was more than half) but now I think it's not on the same level..the petcock was set on PRI the whole time(while not used), was that an issue? Please help!
