Genuine or fake? Your thoughts?

I bought Keyster kits from DS a few years ago and they came in Keyster cardboard boxes and the plastic bags.

That PDF has been composed by me. A few thoughts. Although my carbs have served over 138.000 kms, I have no indication of any wear so far. Each float valve has passed around 2000 liters of petrol. My 649A carbs are stock. No parts have been renewed other than the O-rings around the main jets and the bowl gaskets. Even the O-rings around the T-joints are still the originals Keihin installed in the 70s. For experimental reasons - curiosity - I have raised the jet needles one notch, from 3rd to 4th from top, just to be able to evaluate the setting mentioned in a booklet edited in 1977(!) by American Honda. I still have my doubts; that US booklet is the only source that suggests '4th' for the CB500 and it may well be an error derived from an error in the Shop Manual CB500-550 p.165, where Honda mistakenly typed CB500 over the left column, where it should have been CB550. If one day I have nothing better to do, I may return my needles to their original 3rd (middle position) again.
I didn't know needle jets could corrode. They're brass and what has been interpreted as rust, may well be dried out leftovers from petrol. Needle jets can be cleaned quite easily with grandpa's pipe cleaner. Note that the 'F' models had a differently tapered jet needle than the 'K' models had.

Thanks Gareth, I messaged the company via ebay earlier and they replied that they send them this way so they can send via envelope postage and said he can send pictures/numbers for the kit boxing - and I have requested that in my reply.
