It appears to come from the right side of the motor. This does not happen very frequently so it's hard to chase down.
Anyone else ever notice that sound? What the heck could cause that?

Loose or missing vacuum line?

Again this happens very rarely. I've looked for air leaks with the bike running, using carb cleaner and contact cleaner on 2-3 occasions. and found no issues.
