ya, pretty much how i synced the dual carbs on my 2003 yamaha 1100. i would hold them up to the sun as i was usually working outside and didn't have access to electricity.

Thank you! Buying a 1984 kz550 and wasn’t sure to sync the carbs

Nice job 👍,thanks!

i dont think your method is very accurate. i line up each throttle plate to just begin to expose the first progression hole. its important to snap the linkage a couple times anytime a screw is adjusted to let things settle into place.

I have a Suzuki marauder 800 and it won't go past 70 when I give it full throttle it jerk's and snaps

would a feeler gague work in there too?
