need some help? i was warming up my bike in the driveway for an oil change and it stalled out. not thinking anything of it i went ahead a performed the oil change. tried to start it after i was done and it would not start. gas and choke on but would not start. tore it apart and replaced the spark plug and still no fire. i took out the plug and kicked it over a couple of times connected to the coil wire and their was no spark coming from the plug. any suggestions? about to take it to the shop!
