400ex Won't Start

[FBRacing76]

I rode my 400ex last week went fine started good an everything. Go out two days later and it wouldn't fire. I charged the battery up and there is still no go. Does anyone have any idea's of what it could be? Thanks

Check the spark plug, check to see if your air filter is wet, check to see if there's gas or something in your air box, check to see if your spark plug is even getting spark, check to see if the spark plug boot is on your spark plug...basic things first like that check to see if you need to adjust your jetting too since it's getting warmer out...

Thanks guys it had a filed plug. The plug was completely black on the end. I don't understand how it got filed though!

it could be your jetting sweetie~

thats weird tho because it ran all last summer fine and all winter fine then when it gets back a little bit warmer it files a plug. btw does anyone know what kind of oil a z250 would take? I know my 300ex takes 10w 40. Is that what the z250 would take to?
