Have you stripped down bikes in the past?
Either way, go for it, just make sure you've got the appropiate manuals for the year in question.
Is it a VC engine or standard?
If you want it to be a super clean bike, then taking it apart is going to be the only way to do it.
The 400 lump isn't all that heavy, especially when you compare it to movin around the 600/750/1200 blocks
Mine's currently in pieces in the garage, with the engines one the floor (I have 3 VC ones), hoever I would really recommend a winch bolted in the roof to get the block back in. It's not a 1 person job.
