Shutter at Idle when in gear and warmed up 700 1992

Here are easy things to check, which when I fixed on my '90 750 Regina smoothed out the idle.

1. The vacuum connections on the vacuum sensor. I had a small tear in the vacuum rubber coupling under the sensor (mounted on the drivers fender wall close to the firewall.

2. The harmonic balancer. If the inner rubber strip is dry and cracked this could need replacement.

Good luck getting her running smooth.
