Tuning Making a 40mm Throttle Body

Hi everyone,
I've just joined the forum! I'm looking for someone that still makes larger throttle bodies for SPI engines.
As sparky5 hasn't been active since May '23, I don't think he still makes them, right?

If anyone has other good references, please let me know.

Thanks
