For $2000, I’d expect they would detail what makes these “CR-M31” carbs different and better than the (+/-) $1,100 CR-31 carbs.  Or did I miss a link to an available description?

Scroll down for description. The first set has a modified pilot system, remote adjuster, modified spigot and a much different needle jet nozzle. Linkage and return spring system have been modified for easier pull as well. Second set has all that stuff plus TPS and the harness which allows for ECU ignition mapping (like on Brent Hyde's bikes). They are different from stock CR's.
 George....cash in some of those Krugerrand's that your top flight customers pay you with and pick a couple of sets. ;) ;D ;D

Mike,

 🙄😁

Thanks for the info, perhaps my smartphone isn’t smart enough to navigate that website, or I’m not smart enough🤔

Either way, I wonder what the racing organizations would think of such carbs but clearly the updated carbs seem geared toward that purpose...

Nice!
Fantastic that there are still fresh goodies produced for our old CB750's :) Throttle position sensor. A kit with a bolt on ignition too thanks!

Webike has some nice to have parts to put in basket. Not only carbs and exhausts.
Ooh, forgot that I did not win on Lotto last time... soon.
