I'll take some pics and send them to you in a PM, but these carbs are pure unobtainium. I bought two sets cheap years ago on fleabay just for the hell of it. One set was a bank of 4, the other a bank of 2, and neither the sellers nor the techs at Sudco could tell me what machines they had been configured for. Neither set was configured for 120 mm. centers, so I had to mod a throttle shaft, choke actuator, and bracket. They're the same design group as the current TM33/8012 pumpers, but with differences in the bodies and air horns. It would probably be more trouble than it's worth to bank two TM33/8012 pumpers. You'd have to fabricate a throttle shaft, machine a hole one side of the right hand carbie to let the throttle shaft pass through (line boring highly recommended), and figure out a way to tie the choke actuators together. If you want flat slide pumpers you'd probably be money ahead to order a TM34/B120 kit from Topham Mikuni in Germany or from one of the British vendors. (Mikuni America doesn't import them. May their bean counters rot in Hell.) The kits have gotten fine reviews from a couple of our members; you might send member arcticXS a PM. One of our British members bought the kit as well, can't recall who off hand. The only touchy part is carb boots. The TM34/B120 has the same 40 mm. spigot OD as the VM34. The OE BS34 has a 42 mm. spigot OD. It's been claimed that the sealing ring in the BS34 boot won't line up with the groove in the VM34 spigot. I've tested that claim and it just ain't so; the VM carbs snap right into place. If you remove the OE clamp and replace it with a quality hose clamp, the OE BS34 boot will draw down and seal on any 40 mm. Mikuni spigot. I used those boots for a couple of seasons with my 33 mm. pumpers, which also have 40 mm. spigots, before I switched to a pair of extended aluminum mounts from 650 Central. Not much seat of the pants performance difference, but I had to fabricate spacers and cut a second pair of gaskets with the boots to let the carbs clear the valve covers, so the extended mounts present fewer opportunities for vacuum leaks.
I'll try to get pics to you tomorrow.
