My 2012 yz450f started up for about 30 seconds as usual. Hasn’t been run in a few months. Never had a problem with it in the past. After it idled for 30 seconds it died and I could never get it started again. Tried kicking it and bump starting it 1000 times. Cleaned the fuel injector, checked the spark plug which is fine, changed the gas and disconnected the kill switch. I’m out of ideas and would really appreciate some help with this. Thanks!

Did you check the fuel filter?

Yes I checked the fuel filter and cleaned it the best I could

Did you check the spark? Like with a tester? Fuel lines completely clear? Good fuel pressure?
