I agree on most cars but on the Twins the lines have to be very severely bent to clear the engine when going out the top. I was able to pull it off and so have many others but if I was a dealer I would avoid the risk of destroying the lines. The manual calls for evacuating the AC and I'm sure that is how they would do it.

I agree with you on this point. The wording is a little confusing. I think they were talking about the heads though. My logic is that there is no such thing as a "cylinder head sub-assembly" on this car. There is a head and a "camshaft" housing sub-assembly.

It isn't the flimsy subassembly that warps heads, it's the valve springs that warp the heads. I don't think it would be an issue unbolting caps first if a correct sequence was laid out by the engineers. This just isn't the way they originally intended it to be done.

No it doesn't because the springs are not in the picture once the subassembly is removed.
