  • Cylinder head removal

    Hi all,
    I am a bit confused about head removal.

    According to the Haynes manual:
    "This procedure can be performed with the engine in the frame".
    Nothing mentioned about loosening any engine mounts. Head simply pulled of the cylinders.

    According to these guys, the engine must be pivoted forward and down:

    But I can't get that to work on my frame.

    I've seen some comment that the easiest way is to take the engine from the frame.

    Are the Pre Kat frames that different between models? Mine is '95 750.

    Remove forks, oil cooler bolts, oil cooler brackets, engine is clear to pivot down in the lower cradle once you remove the correct engine mount bolts.

    I didn't include obvious steps like removing headers, lower fairings, so on.

      Hi Kreylin,
      I can't see that working. See picture:

      The cradle pivots in the direction of the purple arrow. It stops on the edge noted with red arrow.

      Or am I getting this all wrong?

        Leave the bolt, take off the nut. The engine cradle will allow for the pivot at that point. never had an issue (it will spread apart as needed). I've done several this way on 88-97 models.

        The 98+ have issue with the welded on oil cooler brackets being in the way for pivoting out.

        Sorry I didn't see this response sooner, new website design is something I'm still getting used too.

          Forgot to say thanks for the comments. Ended up lifting the frame off and leaving the engine in the subframe/cradle. Easier and better access to everything.
