They do sound like 600's My 1998 750 Srad ones are 48 taperred to 40mm.
The chokes in my weber 45's are somthing like 36mm so your 38mm should be plenty for 180+bhp

Exactly the same as my GSXR 600's.
As Wasa said Good for at least 180bhp.

Yep, GSXR 600s.
You can take the outer set of butterflies out and the stepper motor off. It all comes apart pretty easily.
I have just put some pics here Clicky of my set up with the GSXR TB's.
38mm bore is plenty for a 2 litre. I plan on keeping mine even when moving to a supercharger, though I will need some bigger injectors....
