I doubt Sears would carry... maybe an online motorcycle shop would. I can get the Kymco part number for you next week, if you want to try to get a set of the ones that come with the Grand Vista. Otherwise, I'd just go get some big honkin' alligator clips and some multistrand 12- or 10-gauge wire, and make my own set.
Car jumpers will work just fine, but you'd be counting on the car to provide them, since they're so big and bulky.
