There is a place called Bobstar Customs that will make the plates and install a push button air ride suspension for around $1300. They are located in Hendersonville,Tn. They do custom work and have done alot of Yamaha choppers and even a Tn Titans theme bike. I was in their shop one day and saw these bikes. Thats when he give me the ballpark figure on the air ride suspension but I'm not sure the brand of system.
