    GS1150 aftermarket camshaft identification

    Hoping somebody can give me an idea of who makes these camshafts. I have looked for casting numbers on the exhaust cam and all I see is EP-71 on the side opposite the tach worm gear, there is a CWC stamped on the cast along with a C-30 in larger stamping and a C-1 and finally a D-1...these are supposed to be performance aftermarket cams...just trying to figure out what I actually have....thanks

    The C-1 & D-1 tell me this is very likely a stock cam, measuring it to see if it has been reground or somesuch is about your only hope.

      If you have a tach worm gear on it chances are it's not stock. They made aftermarket 1100 and 1150 cams with the gear so the 1100s didn't lose the tach.

          So the 1150s kept the mechanical tach gear but went with the electronic tach?
          Sorry for my bogus info.

            I have 2 1150es. The 84 has a tach gear on the stock exhaust cam and the 85 does not
