I decided to sync my carbs today since I have noticed a little roughness and it's been about a year since my last sync. As I was hooking up I remembered a post from last year where someone asked a question about syncing at cruising rpm or a higher rpm than idle speed. (I haven't been able to find the thread.) Anyway I decided to sync at 2300 rpm, just because it felt about right. I've got to say, it seems smoother than it was the last time.
Does anyone else do it this way or what do you think?
