Do you mean the waxstat thats fed by the collant hoses?
I was possibly going to ditch the waxstat and fit a 'choke type cable' to manualy operate it if its required.....

Hi, hope im not going away from your original question here, but i was just about to post a very similar question. Is it the bit ive highlighted in
the photo? If so i was also going to ask what this bit did and if it was needed? I assume your runnning blackbird enginnes are you, ive just got
the blackbird t/b's to go on an xe with megasquirt.

Yep, Thats the bit i was takling about, its a cold start enrichment stat, allows extra air via small valves.
I'm running a Carb Blackbird engine which i'm fitting blackbird TB's & Megasquirt to (fuel only at the start using the stock
bike ignition).
Plan was to use MS1 V.3 when i get round to ordering it!
Ash.

They are throttle bodies not carbs as I can see the top of the injector, that looks like the fuel pressure regulator.

No, the fuel pressure reg is on the end of the fuel rail.

It is probably just a fast idle valve rather than doing any enriching. Mixture adjustment is normaly handled by the ECU in conjunction with the
coolant temperature sensor.
If this is controled purely by coolant temperature it should be able to get it working with MS, but it will might cause some grief trying to get the
cold start enrichment mapped
MS can control a solenoid type air bleed if full idle control is required.
