Product Description

JNMDamp-Pro - for quieting your engine - from inside the covers. The Aerospace dampening material is layered and constrained viscoelastic (flexible and it flows) damper that converts the vibration energy into low level heat. Shown in the picture is the reflective foil side (foil is a hefty 6 mils). Material overall is 70 mils thick and very dense.

This kit includes magneto cover, sprocket cover, and clutch cover dampening device material cut to shape. They go INSIDE the covers so don't be too concerned with the look before installation, the material is dense and very sticky - yet will just flow to the edges of inside the covers and be contained by the thick foil and the cover, they are peel and stick (white backing) self adhesive. Works fine with our shift kit and our outer clutch cover - in fact used together makes the clutch nice and quiet. Your friends will wonder what you have done to your engine - under $15!!

    I was skeptical before ordering. What can some sticky rubber do inside the cover to kill the sound? I took a shot and placed the order on Wednesday, they were in Chattanooga on Saturday. I can’t believe the difference. The high pitched clutch noise is knocked down 95%. Chain and mag noise is down also. These things should be in every kit. Thanks Sick!
