DOh, silly me, not knowing what I bought
Should have said: Is anyone using yamaha R6 throttle bodies? what size car engine would they be good for, (approx capacity and bhp)?
Not measured diameter, but yep, they are two twin castings - that in theory can be moved apart - and have what appears to be a secondary choke that is
motorised
oh, anyone got the PPC comic mentioned below or can scan the article and send?

PPC did an article about bike throttle bodies a few months back. If you know anyone who buys that comic ask them for a borrow. 
ppc said that 600cc bike throttle bodies are good for up to 200BHP

PPC also says -
inside diameter 38mm
spacing 75-75-75
seperate casting - no (twin )
I've just bought some suzuki GSXR 600 carbs -pre 1999 ,from E-bay for my redtop only £26!!
inside diameter 38mm
spacing 80-80-80
seperate casting - yes.
Yamaha R1's are favoured as are GSXR 750 & 1000.
will get a manifold sorted out later!!
