I saw this for sale locally. Seller says it's for an evo motor but doesn't seem to have much other info. I have not seen it in person yet but I'm looking for some info. He said there is a number on the neck but I haven't heard back on what it is to decode. Can anyone tell me what evo motor would fit? Sportster? It looks like the original frame was cut and the hardtail welded on, but not sure. Thanks
