hi ive been having some problems with my bike like when the battery dies the bike dies so im guessing its the altunator so im looking to buy one

 

what year is the bike???

 

don't forget to get the stator removal tool.. the stator (alternater) is pressed onto the tapered end of the shaft with a square key. it needs a special tool to remove it (its a pita, i tried some other methods before buying the 40$ tool)
