I guess I've had these carbs for about 17 years now and never vacuum synched them until today. Everyone I ever talked to about them had about the same response, they aren't about bottom end and once off idle synch doesn't matter much with them.
Today I finally decided to get the sticks out and check the carbs. All I've ever done is bench synch them and call them done. I always kind of balked at vacuum synching them because with the RS carbs synching is done with the carb tops off. I felt like this is bound to cause a vacuum leak since the slides are now exposed. I took a reading before removing the tops and after, both readings were the same. Two and three were pretty close to each other. One was down 2" and four was up almost 11". So much for thinking a bench synch is good enough. Haven't ridden it yet after the synch, it does sound better though.
