Two days ago my Yamaha FZ25 motorcycle didn't start (it doesn't have a kick starter, only electric starter), I called the dealer's mechanic who after checking if the battery was ok and who knows what else, told me he didn't know what the problem was, he didn't fix anything. He was able to start it by pushing it.
After that it started ok every time I tried: When I came home after the incident, also started ok yesterday (I rode it an hour) and also started ok when I came home, I've just tried to start it today and it starts ok.
What could be the cause for it not starting that single time? Should I be worried? Did that happened to you? Should I take it to the mechanic again?
Notice I bought my motorcycle new, it now has a mileage of 930 miles (1500km). Thanks!
