I took the carbs off the bike to bench sync them, put them back on and now the bike is starting up at 5,000 rpm + and it won’t go down, choke is off. I was afraid of letting it run cold on such high rev, max time was 30 seconds and it won't go done. When I killed the engine some type of fume/smoke started coming out of piston 1 (furthest left).
I've checked for air leaks, stuck throttle/choke cable and it’s not that. What can be causing this? It was running well before the bench sync. I also attached the vacuum sync and all the carbs are perfectly in sync, which they weren't before.
