    Rubber pads between fins

    I've tried doing a search, just didn't find to much info. Can anyone tell me the reason for the rubber pads between the cylinder fins? Mine have all gotten so hard they just fell out. Are they something thats needs to be replaced for vibration or something? Or should I just forget them?

    Thanks,

    That is the primary reason they exist.

    Some people also have the opinion that they help re-direct some air for cooling,
    but the rubber pieces don't seem large enough to do that job.

      Steve,

      Thanks for the reply.

      Anybody have an opinion if they really make a difference? Don't mean to sound cheap but it's 40.00 to replace them.

      Thanks,

        noise control

        Back in the 1970s they started getting put there to stop the cooling fins from vibrating and adding to overal vehilce noise produced.

          They were put between the fins to dampen the "head ring" produced when the valves land back on the valve seats. If you've ever heard an old 60's 650cc Triumph, you'll know how loud head ring can be.

          Take 'em out and enjoy the sound! It'll probably cool better, too.

            No way I'd pay $40 for some chunks of rubber. You might be able to make some out of an old tire if you really want them.

                    They not only stop ringing but also dampen vibration which causes the fins to work harden and break off for little or no reason. Ever see a bike with broken fins that the owner swears he never laid down? This is why. For a couple bucks apiece I'd replace 'em. Just my .02.........8-[
