Cylinder Head Shims

[Fauji]

Adjusting the shims in the cylinder head of my Triumph stag,

Have measured them with a mic and started checking them with feeler gauges,

Here are the tolerances  

INLET 0,006"-0,008" (0'15-0·20 mm.)
EXHAUST 0,016"-0,018" (0'4-0'45 mm.)

On some of my inlet valves I am getting readings from the feeler gauge 0.010” is this accept able or do I need to change the Shims,

How close to the tolerances do I need to be ?

Hi, Im no Stag expert but for 2 thou, especially on the big side, considering the work involved I would leave it alone for another 10k miles and recheck then. By that stage it'll probably sound more rattly and so be worth doing something about. In the meantime I believe you'll lose an undetectable amount of power at high revs.....

Hard one to call.  They are a pain to do but relatively simple.

If it's just the one that is out I'd be tempted to leave it.  That said, on my modern with very tricky to adjust valves there was a pleasant difference after I adjusted 4 or 6 shims out of the 24.
