Synced the carbs over the weekend...
I followed these instructions for the most part
$1.55 Carb Sync Tool by Marty Ignazito
It was really really simple. Bike seems to run a little smoother on the highway now. I used 2 stroke oil in case any got sucked into the carbs by accident. Also did new NGK plugs at the same time.
Do it when the bike is warmed up btw
