Hi, I'm new to the board. I have a problem starting my 99 Magnum 500. When I have a fully charged battery it starts fine. After sitting 10 minutes after a 1 hour ride, motor turns over fine but won't start. 15 min. on charger and starts fine. Tried new battery and same problem. Had new battery load tested and all was fine. Tried pull starting with no luck. Pulled plug and it was dry. Checked for spark and did not have that either. Changed plug and same thing. Bottom line, bike starts fine with charged battery. After that no spark or gas. Anyone have a guess where to start looking for problem. Thanks for the help.
