You need to go test ride a Roadmaster there is nothing you can buy or put on a RSV that will make it ride, handle or perform as well as a RM. Not trying to piss people off, but as a previous RSV owner, I couldn't get over the difference. I myself did the tires, springs, leveling links, shock, and other items. Bike has a terrible center of gravity and very top heavy. I blame this on the engineering design when trying compete with Honda GW which they missed by a mile.
