I've been reading different posts and have seen these different models of wings, all I know that mine is an aspencade. How can you tell what sub model you have? I do remember reading something that said if you have two plastic connectors between the regulator and the harness that means you have a certain model. I have those two connectors, what do they mean? Or can the vin number tell you what you have? Also how can you tell if you have the 350 V stator or the 500 V ? If I have the 500 V I don't need that much power because I only have a headlight, LED combination tail light and LED front fork mounted turn signals. So I am not going to need near the power of a stock wing. If I have the 500 V, can I replace it with the 350V unit? will it fit my naked wing?
