My bike was good an hot when I got home yesterday. It was 98 degrees outside and I just ran it hard. So I had just enough time to sync carbs. They were off but not that far, and I also adjusted them at 3000 rpms too. I took it for a short test run. It seem to help with the rpms rising but they still hang for a monument after throttle is released and it idles about 400-800 rpm after ran above 3000 rpm when hot. I did get the idle down to 600 and it ran not great but stayed running. I set the idle at 1000 now. I'll see what happens once I get it out for a longer ride.
