Carb sinc
This may be a dumb question, but it may be a great one... I have read alot of info on carb synking and found it to be daunting. Trying to have it running, while disconnecting the vac lines, temp. Fuel delivery... What if, while the carbs are pulled off, on my bench and cleaned, I run a shop vac under the carb? I was thinking, with the front carb as a base line, I could measure the pressure with a vac gauge, then set the rear to whatever that was. I know it sounds conveluted, but I would think this would save me from having to T off the vac lines, not have to worry about reaching the adjustment screw, supporting the tank... Let me know if im just being lazy, or maybe, just maybe im on to something

Hmmm? not sure you could ever get that to work.
Balancing the carbs is really a 5 minute job, once you have installed the tee piece and run a couple of vacum lines.
My vacum gauge/carb sync tool set-up cost $5.00 and took 5 minutes to build.

I have 48 years experience working on automotive carbs, but I'd never synced carbs until a few weeks ago.
You don't need to lift the tank. Just follow the instructions on Hawkrider's website.
Once I had the sync tool hooked up and calibrated, it took all of 30 seconds to get them dead even.
It's not something you can do on the bench.

Being lazy!? Your described method sounds way more complicated and labor intensive
than the "normal," or right way to do it. You're over thinking it. Get the little nipple for the front cylinder, and a tee to install in the rear, and your practically done. Do it, and you'll be surprised at how easy it was. Even making your own sync tool is incredibly easy. This aint rocket science.
