Might want to carry the scooter up front. You probably have enough FAWR from that. And if not, you can upgrade your springs up to 5,000 pounds. Bolt-on front receivers area cheap. I bought my aluminum motorcycle rack from DiscountRamps.com and it was priced right, its sturdy, and doesn't weigh too much. I did add extra lights to the rack (driving lights, marker, and turn signal). I have no problem with engine cooling, and the headlights are barely blocked. Just a shadow from one tire, and that aux driving light fills the shadow in just fine.
