HELP PLEASE. 1983 Honda Nighthawk 550. So I am finish up some work on the bike. I got everything put together. New plugs, jets, air pods. When I started the bike it ran nice for 5 sec then POP, and then 2 seconds later another POP. I shut it off and looked. There is gas that came out of the exhaust. Does this mean it's way to RICH? If it is too rich I can fix it but is the engine flooded? How to fix that?
