2002 Honda 400ex starting problem

Hey I hope someone can help me out I was riding my 2002 Honda 400ex the other day and the oil line bolt broke and came off well I was riding and didn’t notice it and it shut off well I got it back to my garage fixed it put new oil in it and now it won’t start! I checked the top end and both side cases everything’s fine turns over like it wants to start but it won’t! I changed the spark plug think it might be the problem but its not I dont know what else to do! Hoping someone has na idea or maybe it happened to them but any information is greatly appreciated! Thank in advance!
