you dont need to make 2 posts on the same thing but anywase did you try a new plug sometimes my plugs have spark and the bike only wants to backfire and wont start so i put in a new plug and it fixes it

Did you try changing the plug after it died this last time to see if it would start? Damn honda250r, you beat me to it. lol
