Time to post some pictures I think.

As I posted earlier I found some throttle bodies from 3 Suzuki TS-1000.
It's a 125 hp 1000cc v-twin bike.
The throttle bodies, as they came. Note the left and right (actually front and rear) body are not exactly the same. The left has the throttle cable "thing" and the right has a TPS, internally they are the same.

Disassembled
The lower part of the body was a little offset, so I had to be creative with the manifold. The flange was cut out on a water jet.

'
Had a flange cut out with the 3.2 plastic spacer as a template.
The pipe between the flanges a just a common exhaust pipe that I cut up and welded back together to get the taper to match the port. Don't laugh at my welds I'm a newbie!
Finished! Later I had someone who I handy with a TIG to weld up the pipe to the flanges (not shown in this picture).
All six fitted to the engine.
Next job is to make some sort of linkage to connect the 3 bodies on each bank to each other. Not sure how to do this yet, my original plan failed, but I have a backup that I will try this weekend if I get the time.
When that is done I will use a cable set up from each bank to a bracket and connect them to the stock bell crank on top of the engine.
Using cables I will be utilizing the progressive throttle opening feature on the throttle bodies.
