Sunny side up? Circlip sharp side vs smooth(er) side

The inner radius is what matters

I thought so too, but looking at the manual, it makes a big thing of calling out the chamfer on the outer radius of the circlip looking at the diagram.

If I try to find which side is the edge side and which side is the chamfered side by feel, I get different results trying the outside radius to the inside radius. This correlates with when I look through a magnifying glass, photos attached.
With the Red side marked, the outer radius has the chamfer and the inside radius is sharp.
With the Green side, the outer radius is sharp and the inside radius is chamfered.

Putting paint or oil on and pressing to a piece of paper doesn't work, we're talking like 0.01mm so it's impossible to measure accurately that way.

Yes I what I thought too, but the diagram in the manual is showing the outside radius with chamfer.

I've had many trannys apart over the years. The circlip grooves cut in those automotive/heavy equipment transmissions are much deeper than the ones I've seen posted for the Rocket. It almost seems like the tool setting for the groove cut was set too shallow. It also appears this is a more recent problem with the Roadsters. Did the earlier 05 to 09 Classics have this circlip slippage problem?
