Prior to receiving my vac gauges (after fitting the 48's) l set the butterflies with a piece of 1mm stainless wire trapped in each throttle body, l adjusted the synch until l had equal drag as l pulled the wire through each throttle body. The next day l received my gauges and check them ... spot on!
Yeh maybe l fluked it, l would never suggest this was an accurate way to balance ones carbs, but, if you need to ride and don't have gauges, it's worth a try.
