Hi,
I made an assumption about rear wheel sprockets that now I am questioning. My “Table” on Sprockets assumes that the PBs were in error and omitted the 51 tooth sprocket for use in 54 from the first up to and including VIN 1688. This is what is reflected in the 57 and later Parts Books. All the Parts Books are consistent with showing the trans mainshaft sprocket being 22 tooth from the first 54 up to and including VIN 1688. So the question becomes did the 54 K up to and including VIN 1688 come stock with a 49 tooth wheel sprocket like the 54 & 56 parts Books reflect or did it come with a 51 tooth and was an omission in the 54 & 56 parts books and corrected in the 57 and later editions? If it matters for purposes of this discussion , if in fact all 54s came with the 49 tooth wheel sprocket it would have the same wheel to trans sprocket ratio as the 56Ks. Anybody got a for sure original 54K pre 1689 VIN they can count the teeth on? As far as the tires go for the 54, “The Legend Begins” shows the 54 as the last year with the 19s being standard equipment with the 18s as optional? The mysteries continue. Thanks for any light you can shed on this.
