Yesterday was my first attempt at syncing carbs, I used a 4 vacuum gauge tool. On first connecting the gauges the left 2 cylinders showed lower vacuum than the right 2. After running more they were closer. I got the left 2 done and the idle increased. I lowered the idle to 1k and went to the right side. I synced the right 2 together and the the left and right. The idle increased to 1500. If I tried to correct the idle it would die or surge between 500-1500. I tried several more times to synch them but ended up with the same idle issue. At 1500 all 4 gauges showed 10 inches. It was getting late and I gave up. Today I started the bike, it started right up with no choke and idled at a steady 1000 rpm. My question is do I have another issue and should I try to synch them again?
