IT sounds like it is the pickups not working (.telling it to spark) if not then it will be CDI UNIT OR ENGINE GENERATOR COILS

SOURCE: Charging the battery over the winter

Hi there. Float charging the battery is a great idea over winter. You should always remove a battery from your bike or vehicle before charging. They produce hydrogen gas (EXPLOSIVE!!) and can easily ignite if a spark is generated (from the battery charge connection) . I have seen this happen before!! I would be using a constant voltage type regulated float charger to keep it topped up. Unless you can set up the constant current type you mention for a few milliamps of charge only. If you charge it at too high a rate, with constant current, it will overcharge the battery and boil it dry. Float charge voltage of 13.5-13.8 is good for any lead acid battery. Check it every few weeks initially to be sure that it is not loosing electrolyte. Thanks for using FixYa.

These issues revolve around the Simplest items ( 8I recall chap had pulled Mach 3 apart , only to have His intended Father in LAW SAY >"WHY'S THIS SWITCH?-OFF?--He HAD BUMPED THE kILL SWITCH AS HE DISMOUNTED!---With that in mind "DISCONNECT , TEMPORARILY THE WIRE FROM THE KILL SWITCH & TRY!--Also, remove coils & Shine Evert Earthing Points, Throughout The Motorcycle., Then carry out Impedence Test Of Coils & DON'T forget the HT Caps , they can produce same woes!!--Remember to "Re Connect Kill switch Wire!--( SDometimes Ignition Swithes Faill Too!--Fact remains>Electronics are like box of matches, not all will light when struck with same force!--Stay Upright, Des.

SOURCE: How do you charge the battery on a 2007 Yamaha

i'm not sure if you are saying how to access it. if you can... just unhook the battery.... attach the charger to it ... be sure you have the polarity correct.... after charging it for few hours.... hook the battery back up.... start up the bike... and let it charge the battery the rest of the way

It sounds like the switch to me, I am just a computer guy, but saw your question in the cue. I feel prettty confident that it's your ignition switch. can you jumper out the switch?
