Should I change the original Pilot jets and Float Valves to new ones?

[Knapdog]

OK, I'll be getting my old Valkyrie back on Wednesday.
Before I sold it a year ago it was running spot on. I'd dismantled the carbs, gave them a good clean and used my Digi Sync to balance them all out.
I'll be taking the tank off as I have a cbr600 manual petcock to fit.
I have half a mind to change all the pilot jets and tiny o-rings since they're 28 years old. (  I think they're the Pilot jets. The ones you turn out 2 and a quarter/half times for rich/lean). The reason is that I'd filed a slot in them to make it easier to turn with a screwdriver and my first attempts weren't great.
I've purchased six sets of carb rebuilds (made in China) and wonder whether I should fit new ones.
The kit also has new Float Valves. Would you replace these also as I'm thinking the new rubber ends would be a good fit.
Or, of course, would you say leave it as it is.
The owner, for the year, only did 800 miles so I don't know if the bike was static for a period with an ethanol lacquer build up there.
Any thoughts?

I'd ride it for a bit before deciding to do anything.

NO and NO.  Honda used a higher grade of Buna-n for the o-rings.

which grade do u think china use?

age has nothing to do with Buna-n going bad.

OK. Thanks.
What about the actual Pilot jets?

Replacing 28 yr. old rubber is becoming an issue on our bikes thus replacing the "float" valve is definitely a must. As for the brass jet's, needles etc., I wouldn't replace them just a careful thorough cleaning.

no reason to change them.  if u want a clean intake system including the ring pack and an increase in MPG and keeping the needles inside of the needle wells lubricated look into TC-W3, I've been using it for yrs. the needle wells in these carbs are not replaceable.   read here about it and ratio to use.

The genuine Honda float valves in the UK are around £27.
Another thought... Wouldn't the genuine Honda ones have been hanging around on the shelves and be almost as old as the ones on the bike?
