I added the Center Stand to my Bagger last weekend. It took me about four hours because I had parts but no instructions. It was the first major work I have done on the bike, so I took more parts off the bike than I had to. After getting everything back together, I think the work could be done in an hour and a half, maybe two. I added the center stand mainly because I plan to do as much maintenance on the bike as I can, the center stand will make that service work easier.
