Hi, I have a 2004 LTZ250 and I am having a problem with it starting and dying on me. If I start the bike and let it run for awhile it is fine, until I try to put it into gear and then it dies. Also, if the bike is warmed up and riding for about 20 minutes, if in neutral or stopped in first gear it will die. I'm thinking clean the carb, any other suggestions?

 

definately clean your carb, have you had your valves adjusted?
