Power loss trouble shooting?
I just received my Dad's mostly restored R60/2. I asked the shop where he lived to get it tuned up and dialed again, and they cleaned the carbs, checked valves and replaced spark plugs, checked ignition and magneto timing, and replaced battery.
It took a good number of kicks to get it to start, but once it did it seemed ok. I noticed it had an odd propensity to get throttle when I turned the handlebar to one side, so I clipped a zip tie that seemed to limit movement of the cables.
Yesterday while riding I noticed a significant drop in power. I think I've identified that the right carburetor is acting up. When I give the left side some gas it seems to respond appropriately. The right side, seems to lug and struggle. See video: https://drive.google.com/file/d/10s5yyh ... drive_link
Any ideas on where to start? This is my first ever motorcycle and while I consider myself handy, I don't have the experience to trouble shoot this kind of thing.

An oddity that caused me confusion last year is that there is a steal liner where the needle sets into the main jet oriface (sp). Remove the air intakes and look into the carbs. The left and right should look the same. The steal liner should be close to flush
When it happened I had to kick it over a bunch of times before limping home, luckily only a couple miles.
But odds are it is a plugged jet as kenboy said. I don't run gas filters, but if it has sat for a while you might want to put one in the gas lines.
All on the road, going no where in particular in the Finger Lakes of New York
