Loose shifter bolt prevented you from getting the bike into neutral, then you flooded the bike trying to start it in gear. When it lit off finally it farted.
Tighten the loose shifter bolt, change your underwear and you'll be good to go.
I have come to terms with the possibility of dying while riding, life has a 100% death rate. I would rather live having fun and end up dead in a motorcycle crash than never do anything fun because it's dangerous and I might get killed. No one makes it out alive anyway. - From a friend on another forum, used with his permission.
