Carb set from Mr. Edmond at ETD is $700. Carb set with cable and fuel lines, no filter - bolt on and go.
He's a good communicator.

You know that sounds really good to me after spending all summer taking stock RZ carbs off and back on.

Still imagining that the left carb is dragging me down, (but it wasn't before)

Previously, the clutch was inspected, looked good, and assembled.
This is a fresh 2nd over 64.5mm rebuild. It was a cooler day and has a better ignition curve. Toomey pipes.

Seems that that combo of factors was too much. Seat of the pants said not much power delivery loss, but revved to 10k and stayed there while increasing speed.

Maybe it was right on the edge of being insufficient all along.

Rode today to prove that I could make it to your place, Mark.
Did well enough for that. No fuel flow issues anymore.
Clutch slips at max power delivery.
To me, that is actually good news.

Are FZ1 clutch frictions still the way to go on an RZ?

I did use that on my 400, Milan. Bought from some dude in the UK a few years ago.
Still quite happy with the result.
I would consider using Mark's solution along with it if I didn't have plenty of other issues to work on.
No leak here, but it eliminated the wiggling in the shaft that you don't necessarily notice on a 7500 mile bike.

You are a patient man. Nobody here would blame you for transplanting a YZ250 mill into that thing.

I'm guessing that you can't get away with that in CA.

Headlight positioning is impeccable.

I do lust after those pipes.

That black T500 just looks too right.
I don't have FBook, but saw this in images for Ed Toomey Designs. Ed has had his clappy hands on at least one, (that wasn't as good looking).

Likely needed, as I can't figure it out and it would be foolish not to know and just get new carbs (when it's something stupid and unrelated that I might have done).

Speaking of new carbs:
Which PWK's from which Toomey?

28mm for stock porting and non-stock programmed curves?

They take oil lines?

Just rode it with needles as high as they can go plus a washer.

Seems like a needle shape/emulsion tube issue.
Mark, I don't recall your above idle iggy curve number, but maybe the stock carbs and internals can't deal with it.

Idle is fine, opened up above 4k is fine.
Part throttle and lower rpm brings some unhappiness. That's where the YPVS is supposed to be helping and there's sputtering instead of some grunt.

I was at the other side of the needle adjustment too and it was a bit little worse. It's just not there with this hardware.

I'll drop back and punt, hoping for a growth bonus from work for January 15th. Those carbs have been off and back on at least 10 times. I got good at it. That will help me for the rest of my life 

The needles are getting lifted to the point that I am wondering if another emulsion tube is needed. Gonna go another step - step and a half up and then investigate going up from 375 O-8 needle jet to whatever is next up in flow.
That is not obvious by looking at Jets R Us under VM26 round slides. There is no 375 anything.

Hoping for success before I run out of needle jet.

Gratuitous photo included, featuring the higher flow Yamaha fuel valve that has been suggested.

You can see which of these will NOT have a fuel feed problem.

That tank after paint   

That is one top hybrid project.

That 1A1 crank is a keeper, compared to the Daytona Special crank. That is, if everything is what it seems to be.
There might be more detail to that assumption, but others can certainly chime in.

Excellent bike as it is - really!

Thanks, all of you!
