Thats the big difference mate, old british iron was designed for ocasional sniff of the red but japanese was built to have its neck wrung, can remember the exact wording but the 500 owners handbook says it is fine to go into the red but not out of the top for extended periods!

6000 is no where near the red line and dont think its anywhere near the 85% i would cruise at, cameras permitting!

Honda part numbers are not complicate, the first numbers tell you what it is, the middle three what model first used on last three manufacturer or country code or supercision code so 283 is the model code you need, the supplier said sounds like 280 which is different

Part number is 41201283000 so i would say 283 not 280 but that is a pure guess

Yes it matters and should be marked if genuine

That was a good haul, too much and too far away for me, at least 3 of the rear brake pedal retun spring in there

Honda always list alternate sprockets but they were designed with a ratio and yes, compared to british iron, they do seem to rev high BUT its higher up the rev band they give rated power, the 500 handbook says not to go out of the top of the red too often

Have you considered that running 17/35 sprockets has dropped your revs for running speed and may be contributing to your running problem? It was designed to cruise at a certain rev range

Do you not have an old sprocket to give him?

I did some math and 17/39 is damn near same as 15/35 and the cms one would  be here fairly quicly.
The rear sprocket part numbers only fit the various 450 models according to cms so probably not easy to get aftermarket now

15 to 17 is a big jump, personally i would fit one of the bigger rears from cms to compensate
