KZ650 Sleeper Build (KZ1000 engine transplant)

I put my adapters on the same angle. One of the long ones broke off with the vibration so I used JB Weld to anchor them to the carb body at the float bowl flange. They work great. Miller used M6 bolts drilled out to make his and they looked like SHT sticking straight out. The inside ones were too hard to get to. Used grub screws and JB Weld to plug the old holes.  
Yours look good too.

Those adapters have been sitting in my jet box for over 10 years, first time I have taken them out and screwed them into anything.

The only other carbs I have that need to use those are the GSXR flat slides I have. That is what I bought them for originally.
