Put more simply the camshaft is fed from the right side loop the chain through the camshaft first, then feed the lobes through the sprocket. Doing it this way results in the chain being on the right side of the sprocket & boss on the camshaft.

Wouldn't it be easier to fit the sprocket past the lobes whilst it's off the engine Ted, leave it hanging next to where it fits and then thread it thorough the chain?

As Ted described, the trick is the initial set up as pictured. The trick is to engage the chain on the sprocket off the cam, rotate anti-clockwise to locate the first bolt then turn clockwise to engage the second bolt. Check the alignment. If it’s incorrect reset the process, but compensating for selection of the correct cam tooth. I know you know that by the way, Ken.

It's difficult to explain but if you do it that way I found the left end of the cam grounds on the head well before it can reach the end bearing. You need to end up with the chain on the right side of the sprocket not the left. Phil's photo says it all.
On a used chain it might work if the chain is on the left side.

I'll name that tune in one Ted... Telly Savalas 1975, "if a picture paints" amusingly from the right period for these bike too ;D
You're right Ted, it's awkward getting your head round some of these fiddly assembly just from description. Once into place though you can see just how it's done.
