Its a pice of cake. After you remove the battery and box and I removed the driven clutch and belt just to give me a little more room. That was the easy part. Braking my arms in a dozen spots and stretching them anther 6ix inches was what hurt the most. You need to do that to get at the bolts. Other then that, Its not to bad. Its one job you only want to do once. So that is a good reason to go HD right from the start. Then you do not have to worry about them.
One more thing , Been able to work upside-down Is a big bonus.
