Hi. New member here from Sweden! As said before, the "older" KLE 500s are using 112 main jets, but to add some info; they are using 2 jet needles with the mark "N96J", but everything else should more or less be the same (from what I've "gathered"). The new ones are using different main jets (92 and 95) and needles (N96L and N60D), probably due to the fact of different header lengths (I'm more or less 100% sure the older KLEs are using the same exhaust, but they are having the same (as in sizes) main jets and needles).
I can't give you a straight answer about the cam specs, but I am sure they should be the same, if we compare the older KLEs with the newer KLEs (but do NOT take my word for it)
I hope this should help!

(swedish page, though he inspected his carb and his info were the same as the link above, so I am quite sure the information should be correct)
