Check for spark, and air and fuel. If untreated, drain the tank and put fresh fuel in as a cheap start. The manual trouble shooting is the best way to go. Hard to say otherwise as the forum guesses. The plug doesn't show a positive or negative to me.
Woke up this morning and also thought PC. If you have a power commander and disconnected the battery through the winter make sure you hooked the PC up to the correct battery terminal again (positive) and that it has power when you turn the bike on.
