As long as you don't have any frozen bolts, it should take you 2-3 hours if you are organized and don't have any real problems or totally worn out parts. It helps to have a buddy there to assist with a couple of the operations with the bigger pieces, and if you do have to hammer out a bolt, it helps to have someone hold the bike so it doesn't fall over. Otherwise, you just have to lay it on its side. That said, I did the rear susp. on my brand new 426 in 1:45, but I had just taken apart a 99 400F that gave me some trouble a couple weeks prior, so I had plenty of experience with that particular model. Above all, I would say have patience, be organized, and don't take shortcuts. The faster you want it to be done, the longer it will likely take, adding to any frustration! That's Mr. Murphy hard at work for ya! :)
