Suggest you try the German distributor.

Also worth a call to Big CC Racing, who used to be the uk distributor, I think, in case they have any spare sets left.
I have a set of carbs for sale with an F Pro kit installed, but they also have a Flo Commander on, which you can't remove, and are part of an enlarged airbox, with the tubes and the catch tank moved externally to the airbox, airbox volume is increased.
The snorkel is enlarged for better flow, and a K+N fitted.
The carbs have the connectors for the carb heater coolant pipes cut, but I have another spare set of carbs which can be cannibalised if you need to connect the heater pipes.
I ran it without for years and never had carb icing.
To build a good jet kit I just bought main and pilot jets, and some spare needles etc, and mix and match my own sets.
The only thing you don't get easily are the springs, but you don't get those with FP kits anyway- they use std Honda ones.
I prefer FP simply because you don't need to drill slides.
Do you really wanna play?
Jetting these can be tricky; that's why I built a real-time Lambda sensor display, showing each cylinder's air/fuel ratio in real time. This meant that I could do it myself without needing to pay a lot of dyno runs. It comes with a set of std downpipes with Lambda sensors welded in.
All for sale, should you (or anyone else) fancy a real custom setup.
It's not falling off, it's an upgrade opportunity.
The main cause seems to be the cans which are exceptionally free flowing, and loud! If the Dynojet kit is more accessible In the UK and does a similar job then I will go with that.
