"Balancing Slid Carbs - 1st thing I do is place a stop like a 6 or 8mm Hex in the throttle bore (Mechanical Slid Stop) and adjust the throttle cables to sync on shutdown so that you hear "ONE CLICK" - Not one followed by 2nd or 3rd as with a triple"
not good enough Ron,
I did this for years until I decided to buy the right kit, which was later sold and even better kit purchased and that is about to happen again, times change, technolodgy improves, but when I first had vacuum guages I was using my SF1 as a daily ride and didn't own a car, once balanced using my new gauges the bike was a very different ride, it would tick over for a fortnight (never a good thing on a 750 twin to tickover for long periods due to oil circulation, my first cams from new only lasted 36,000 miles, I learned what is now common knowledge the hard way) it was a much easier bike to start, hot or cold, a bit more frugal, maybe, and would rev very cleanly all the way to and including WOT. The biggest gain was mid range vibration at motorway cruising speeds, in those day 80/85MPH, smooth as a Rollers bonnet polished with 3000 grit.
