    My cylinder head is a bit warped. If I put it on a flat surface then I can get the 0.03mm feeler gauge and sometimes the 0.05mm feeler gauge between the flat surface and the cylinder head at a couple of places.

    Is it okay ore to I have to take it to a mechanic to get it 100% flat?

    I cant find anything about the service limits in the manual.

    It depends on what type of surface you are guaging it on. Is it a surface plate or heavy glass ?

    If it is then I would surface it. If it's not, then I might try to verify the flatness of the surface you are using.

    Are you having leakage past the o-rings?

    I have used two diffrent mirrors, the results are the same.

    Ther is water leaking out from the cylinder head nuts.

    Edit: Maybe I should use “liquid gasket” + the o-rings. The former owner of the bike dosen´t seam to have used anything accept the o-rings

    Now I feel stupid... :doh:

    That would be a simple answer. Not leaking- don't fix. Leaking-fix it. Probably can be precision ground by a good machinist.

    Tape a sheet of 400 grit sand paper on the heaviest mirror, or both together and hand lap it flat. Then get a new set of the OE o-ring / washers and it should be good for it's next life.
