Getting Back In - RD500 Carb Sync

[Milan]

Getting started again on all my bikes.
Those hurricanes last year had me moving them all over, as well as damaged stuff.

I got my V45 Sabre out & cleaned the carbs.
Used the Digi-Sync to calibrate them. Worked great

I have my RD500 carbs off for cleaning, but I did not see any connection ports for the Digi Sync.
Maybe there are none & this wont work on this bike.

Popsicle stick method then?
