Hey guys. I have a '03 yz450f. I have the headlight/taillight ready to put on, but I just cant see spending $500 right now for an e-line stator. So I am going (try) to mount a battery in the airbox. Has anyone done this? What battery did you use(dimensions)? And how do I go about mounting it securely? Will anything from a wr work? I'm itchin' to get this thing on the street. PLEASE HELP!!
