I was riding it, I got off for about an hour, went to start it again and it wouldn't start. Its gettin gas and its getting spark at the plug. The oil light comes on for a second and the nutral light comes on and stays on while your trying to start it. I don't know what it could be, do you think it could have jumped time? And how would you go about checking the timing? Any seggestions on anything would be appreciated. Thanks.
