Vibration reduction of Instrument Cluster on 83-85 Venture. I have experienced a lot of vibration / bouncing of my instrument cluster on my 83 Venture when riding on rough roads. I recently had the cluster off of the bike and found that the two brackets that mount the cluster to the fairing sub frame had excessive play in them. There is a rubber grommet over a shoulder stud at two points on each bracket for vibration dampening. I placed a new 3/8” washer between the existing washer and bracket to reduce the free play in the brackets. The 3/8” washer will fit over the shoulder of the stud allowing the bracket to slightly compress the grommet some more. The existing washer is replaced back over new washer and will only allow the nut to be tightened until contact with the shoulder of the stud. When the washer is placed correctly and the bracket is bolted back on the cluster, the threads of the stud will be about even with the back of the 10 mm nut when tightened. With this modification in place, the vibration of the cluster has been significantly reduced. There is still some flexing of the cluster that will absorb road vibration, but not nearly as much as before. The 4 conductor connector in the1st picture is for my shift position lights. The mounting bracket for the cluster is removed in this picture. The mounting studs for it are to the top left and bottom right of the electrical connector. The second picture shows where I placed washers. Gary
