I got a gn250. When i had problems starting it was the battery. Did you check the battery? Are the levels full? You uh turned the gas on right? hey i had to ask. Maybe you could crash start it. get on a hill and put it in neutral get a good roll on and wack it into 2nd. and i think you gotta jump on it with your butt at the same time. careful you don't slide out. If that works maybe it was just..tired. But if it still has trouble starting i dunno..the fuse?
