This myth that keeps getting spread around is NOT TRUE.

The vacuum that operates the vacuum operated slide is from the engine suction when the piston goes down and of course atmospheric pressure that day, and at that level above or below sea level.

The reason for the vacuum operated slide is so that at different
altitudes or weather changes the carbs would not need adjustment .

EXAMPLE: You live in Tucson Arizona (alt.2000ft) and you decide to ride up to the top of Mt. Lemon (8,000) feet.
Normally the air would be so thin that the engine would start running very rich and not want to idle.
 With the vacuum operated slide that condition would be compensated for.

See what I mean?
