try cleaning your carb. you might have gas in the tank but usually if it
starts and run for a few seconds on the startig fluid, it is not GETTING
GAS TO THE CARB. try shooting some carb clleaner into the carb and try
starting it on just the carb cleaner NO STARTING FLUID! if you mix both
together you will have a fire.
So shoot a little bit of carbcleaner into the carb and try to start it.
if that does not work take you carb apart and clean it with carb
cleaner. there is not anything major wrong with your bike.
hopeing for the best,
let me know how you make out.
