    Regulator Rectifier Cooling

    I found an interesting site, which I thought I'd pass on:

    Honda VFR 750 Regulator / Rectifier
    http://www.one-ring.net/vfrfaq/reg-rect.html


    It may be old hat to some of you but I'd appreciate some feedback

    Well, thankfully our GS rectifiers have heatsinks on them.. I wonder if milling the fins off and epoxying say a..... athlon cooler on it would do for the life of the rectifier. Or maybe just a fan on the stock part? there's a guy who rides a meanstreak who mounted his rectifier outside and in the air.

    If you love it, let it go. If it comes back....... You probably highsided.

    1982 GS650E (really, it's a 650)

      The only thing that runs hotter then a GS RR is prolly an athlon. I have some nice copper heatsinks laying around, but they stick out WAY too much to go under that side cover. Maye relocate RR to the front of the frame, where it gets lots of airflow.


      the best cooling i have done on a PC is watercooled peltier, wonder how that would work 8)

      Good article by the way

        On my bike the rectifier points at the rear fender, not the sidecover ;-) so I have room for it. I'm seriously considdering just making a bracket and having it hang out in the breaze by my rear frame.

          On the 1984 GS1100GK, the regulator/rectifier is located way up high, under the left sidecover -- out in the breeze, which is good. On my previous 850's, it was under the battery box, which is not so good.

          I have my original r/r and stator on the GK, which now has over 81,000 miles on it. It took a while for Suzuki to get things right on the GS bikes.

            I replaced my R/R with one from a 1999 CBR. Better unit, less heat, won't fry the stator. (Ebay, $25)
