Hi all. Converted my Kawasaki Vulcan 500 back in April this year. I'm from Nor Cal, and did the conversion install myself. She runs like charm. love triking. She pulls just fine for a 500 cc. The Vulcan 500 has the Ninja 500 motor. It revs up to 13k and has plenty of pull for 2 up riding. I also own a Piaggio Mp3 400.
