    Which cams?

    Dear All,

    I have a 1979 GS 750E which grew with the aide of an 850 block. This all happened nearly 30 years ago, I can't for the life of me remember if I used stock 750 cams or 850. Too many beers have passed under the bridge! Wonderful stuff, who are you again? I've attached a pic of cams which shows 450 stamped on the sprockets. Just what does 450 mean. DSC_0040.jpg I aplogize in advance if i don't reply straight away, the days seem to be shrinking.

    “Remember When in doubt use full throttle, It may not improve the situation ,but it will end the suspense ,
    If it isn't going to make it faster or safer it isn't worth doing

      On my 750/850 conversion it has 750 inlet and 1000 exhaust cams. I've tried other standard 750 850 1000 cam configurations and there's not much difference, you would need a dyno to tell any improvement.
      My bikes 79 GS1000 1085 checked and approved by stator the GSR mascot :eagerness: and 77 GS750 with 850 top end, GS850g, and my eldest sons 78 GS550, youngest sons GS125. Project bike 79 GS1000N

        Thank's for your replies guys. I'll keep digging around and try to find what 450 represents.

          It is part of the part number for the sprockets. GS750/850 use the same sprockets. GS1000 uses 490 sprockets. The sprockets determine the cam timing. GS750 intake sprocket #12740-45002. GS1000 intake sprocket #12741-49001.
