Sportster clutch
The spacers for the stud plate (OEM5995) measure 1.525, they come 6 per package. There are also spacers -.040 and -.080 under size, I assume for clutch wear. Why are they 6 times more expensive than the standard size? Anything special or just under size by .040-.080?

There isn't anything special about those, I haven't never replaced normal length "tubes" . Only situation that I know when it was forced to use shorter was in racebike, it was difficult to have clutch lever correct... easier and cheaper change clutch plates.

Usually clutch slipping in normal (not heavy tuned) bike is related to transmission fluid. 1. Too much oil 2. Wrong oil ( use sportster transmission fluid) 3. wrong adjustment ( most common) of base and cable. ( procedure other topic in forum)
Correct oil isn't so easy case, pre -77 has transfer valve in primary witch allow motor oil and transmission fluid to mix. Factory recom use sportster transmission fluid to all 71-> wet clutch sportsters. I have used both, same oil than in motor and sportster transmission fluid.
Clutch and tranny works smoother and better with transmission fluid, but now I have -78 bike without transfervalve.

Like Sepixlh said, the main thing is that the tubes are all exactly the same length.
The 6 tubes are a change made to the 'late' 1974 Sportster clutch.
The purpose was to make clutch alignment a thing of the past, and it did that well.
I have a 1971 XLCH and when this change took place 36 years ago, I made my own set of spacer tubes. They are still the same tubes in the bike today.
The recommendation back then was to place all 6 tubes in a pan of water about 1 inch deep and have the tubes standing on end.
Heat the end of the tubes with a torch to a near red heat......... then bump them over in the water.
Doing this hardened the end with the quick quench. You did this to both ends of all 6 tubes.
I think the fact that I still have mine in the clutch after all this time says it is a good way to do it if you make your own.
