I just bought the second or maybe third hand GSX 400 impulse from the bike shop. When I bought it at first no problem at all during start, I thought ok maybe is summer time no probleam what so ever in the first 2 months.. Now we are in raining season, and I ran into major problem it just won´t start. I press down the start button until ran out of battery and still won´t start. Anyone have this problem please help me Out what should I .
