i have a 1999 honda trx 400 ex. and it wont start.
i was riding the other day and it started fine and ran perfect but today i tried to start it and didnt start.i changed the spark plug and it gets blue spark and i also changed the oil. does anybody else know what it can be.

 

is it getting fuel? air?

 

yes its gettin fuel and air the problem that it was is that the battery was dead so i jumpstarted it from my car and runs fine now.
