I'm new to quads . I am mechanically inclined, but still a rookie on quads. My son bought a 2007 Honda 400 ex and it has been great so far. Today while riding, it simply stopped running. When we put it in neutral, it will not turn over. Key is on, lights work, but the starter will not turn the motor over. It will not bump start either. Battery has good volts, fuse is good - what else should I be looking for?

 

low oil. newer quads like that will have a low oil shut-off.
