The Digi Sync 2-Channel (Model DS3+) Throttle Body & Digital Carb Sync Tool

I’ve used 3 other carb balancing tools. It will take more experience to get used to this one. But a key feature it has is the RPM counter, which helps massively when adjusting the idle/air-fuel mixture screw. I do like that I don’t have to hook it up to a battery to run it.

I used this on my R90/6 and it seems to work very well to get the carbs synched.
