Not that hard Steve. Body work, air box etc. off.
Injectors and cooling system out of the way. Exhausts off.
Get all the wires and cables out of the way then three bolts and your there
A bit simplistic, but you get the picture
The only usual problem is the swingarm pivot. If it's seized, then you may need another 4 hours.............. if you're lucky.
Refitting is, as they say, a reversal of the above. Get a Haynes, a helping pair of hands and your tool kit and you'll be off!!
