    yes another valve adjustment thread

    Trying to finish a vavle adjustment.

    Misreading the instructions ; waiting for shims; demands of life; limited time; and frustration have made it a long process.

    I am having trouble with one valve (4 exhaust). It read 0.10 with a 2.55 shim present. Using a new 2.6 shim (as suggested by Steve's essential spreadsheet), I cannot get my .04 mm feeler guage to even fit between shim and cam.

    Too frustrated to do a search.

    Suggestions?

    Are you sure its a 2.55? Use a set of vernier gauges on the shim to confirm its size.

    Have you checked that the cam is in the correct place for the timing and checking?

    Is the new shim sitting in the bucket correctly?

      Hi,

      If the measurement is correct, there's nothing wrong with 0.10 mm clearance on an exhaust valve. "A slappy valve is a happy valve."

      I've run a couple of mine at .11 mm with no adverse affects.


      Thank you for your indulgence,

        The shim measured 2.56.

        I rotated the enigine several times to seat the shim after insertion. And the shim bucket is able to rotate after I remove the tappet tool.

        I measured the new shim at 2.61

          The bike is fine as Basscliff says. Button it up and go ride.

          To measure is to know.

            It's fine at .10 but if you have the new shim in and it measures less than .04 it may be tight now. It may be at .03, the lowest in the acceptable range. Sometimes I get slightly different measurements on the same gap. Maybe it was actually .09 with the old shim and barely below .04 now. Are you sure you didn't accidentally have another gauge stuck to the .04 gauge when you checked it?

              appreciate all the suggestions

              Thanks to all!

              I will double check my measurements but am fairly sure they are correct.

              If so it will stay at 0.10 and back together it will go!
