The picture with the adapters also includes restrictors. These are the WHITE BEADS WITH HOLES. I have already explained their use. They slide into the HOSES up where the hoses join the plastic tubes that contain the mercury or oil or whatever...
The adjustment tool is available through K&L Supply which means
www.z1enterprises.com can get it. It is an 8mm socket with the flat blade screwdriver in the middle. I NEVER use this tool for VM type carbs... I use a long blade screwdriver to hold the nut and an 8mm box wrench to tighten the nut. ON Z1's with outer adjustment nuts, I use a special wrench that I fabricated due to clearance between the nut and adjustment mechanism.
I use the tool pictured on all CV style carbs that have a locknut/screw adjuster for sync as you CAN NOT reach these with the carbs on the bike otherwise.
