The second time out on my 2003 sherco 250cc and she wont start. I jammed my wee finger on the edge of the shed door when I was putting her away last time out. 
So I blame this for forgeting to turn off my fuel. 
Does anyone think this could be the reason she wont start. She did go for a few seconds and then nothing. What might I need to do? 
Jump starting would be an option tomorrow when it gets light. 
If so what gear should I use. 
Thanks in advance folks.
