Anyone have some input on what all of this is? See the photos.
I was exploring in boxes and found these. One of the springs was tagged with part number 40302-52. That is for a K model according to my 57 Sportster and K Model parts book. The spring shown in my K Model parts books doesn't show the tabs that make this a torsion spring. The compensating sprockets are dual row 21 tooth and fit a tapered sprocket shaft with a key, like the 1954 back to 1938 big twin style shaft. These compensating sprockets do not look anything like the diagram in my 1956 Big Twin parts book. I see that Harley introduced a compensating sprocket for the 1938 to 54 big bikes in 1954 accessory catalog. That compensating sprocket isn't listed in my 1961 parts book, so I think it was discontinued by then most likely from lack of sales.
Thanks for any insight you can give me on these. belmont
