I have a honda shadow with V twin. and i tipped it over the other day. now i cant get it to stay on! i turn it on and it dies maybe 3 seconds later. and if i give it any gas it dies right away. well 20 mins ago i started it and for the 3 seconds i knew it would be on, i i put the choke on and it started up and started running fine. so i turned it off. and 10 mins later the engine wont even turn over. plz help!!!
