I read that post and knew that *one* of us was having a brain-fart... Just assumed it was me, as usual... <grin>

So since you've got that sensor, where do you have it reading off of?

A buddy of mine has a Honda inline 4 bike that's aircooled and he's getting pissed because of all the trouble's he's had sync'n the carbs (1 per cylinder), and I'm about to suggest the MS to him, but I don't know what he'd use ...

anyone got any ideas?

It's not quite the same, since the fuel delivery is always good with EFI (well, mostly). The problem with too large a TB is that at low rpm, you go from low kPa to 100kPa with very little throttle movement, making driveability 'worse'.

For example, on my car, with a 900 cfm TB (4 x 1.750"), I can ...

I've got a throttle body sat here - 48mm off a Metro 1.4 K-series - but I can't help feeling it might be a bit big as a replacement for a 26/35 twin choke Solex. This is for a two-pot 602cc Citroen.
