Thanks Seth.
I am having a blast on this bike. Nice mild August here in Virginia so riding has been perfect. I finally got around to vacuum sync the carbs. Here is my set up.
My remote tank is off of a busted down pressure washer courtesy of local small engine repair shop. Price - free. I then mounted it to a little wood 90 degree bracket with hangers to hold it above the bike.
From the front side, it looks like this
Prior to doing this sync. I double checked valve clearances, point gap, timing, and also searched around the various bits for vacuum leaks in the old rubber. Once all good, did the sync and this bike now runs quite nice.
Just enjoying the ride now.
