Topic: DIY 5$ Carb Sync Tool

That would make ALL the difference. The Honda ones at bought at that time, didn't have that feature. I have no idea if they changed to adjustable gauges, in the later gauges Honda sold as I had already moved on to the Carb Stixs.

All gauges have a calibration screw. Adjust to a single source and adjust. Attach them to the carbs get them all reading the same, you carbs are synched. Building your own may be fun, but riding is more fun.
