By the way, the jet projection you show on the hex jet is very close to what I am used to seeing. You can just get a wrench on it to change it.
That's why I changed out the bowls. I have changed jets on the standard XL carbs without removing the carbs from the bike, but it's a bit of a pain taking both the bowls off. With the XR5 bowls it looks like it's just drain the bowl, unscrew the cap, and get a little ratchet on the jet. You're post about your XR carbs inspired this mod actually.
As for the the PH64 carbs, I haven't come across a set of those yet. Someone did a write up of XL carbs in this thread somewhere and I think those ones were from a California model.
