    Cylinder Head removal 850G

    I am going to be replacing a head gasket and was looking through the manual that Cliff had on his site. It appears that the cams will have to come out in order to facilitate head removal. I just set the lash on the valves and was wondering what the chances would be that after re-assembly any of them would still be correct. I'd always thought that one of the beauties of OHC was that the valves would stay set when the head came off. I guess that was cars and this is motorcycles.

    I changed mine a couple of weeks ago on my GS750, and 6 of 8 clearances were exactly the same. The other two were only 0.01-0.02mm different. And I that was after changing the valve stem seals too - didn't lap the valves though as the surfaces looked spotless.

      Changing shims is easy. What are you worried about?

        Unless you're a magician, the cams have to come off. The drive chain goes up the center.

          To answer your question, the valve clearances really shouldn't be affected. But you will want to re-check them upon re-assembly. I mean, you're right there...

            When I replaced the head gasket on my 750 earlier this year none of the valve clearances were different - I did however re-check them all...

            I would be more concerned with making sure the cam chain gets re-installed correctly, & not off a tooth or two.

            Good luck,

              Yeah. Surprisingly easy to get that wrong. Especially if you do it at 2 or 3 in the morning, or whatever time that was.
