my battery went dead so i stuck it on the charger, then when i put the battery back in and tried to start up the bike i heard a high pitch sound then nothing, now the bike isnt getting any spark in the spark plugs.. help?

 

Hope you haven't connected the battery up the wrong way, Otherwise my guess is the battery is stuffed

 

yea, lol.. im not that stupid it wouldnt be a high pitching sound,
it would be more like sparks and battery acid going everywere..

 

Yeah I've heard of a friend of a friend doing it, don't know what it does though. Good luck with it
