Valves too tight?

According to my Haynes manual, my valve adjustments are:

0.004 to 0.006 for Intake
0.006 to 0.008 for exhaust

So, on the exhaust if I have a cam lobe 180 degrees away from the adjustment shim and my 0.006 feeler won't fit between the cam surface and the shim, I need to reduce the shim size. Correct?

In fact, the 0.006 feeler is the smallest one I have and will fit under only one exhaust valve. Even the 0.008 feeler with slide under that valve with slight drag. The 0.010 feeler doesn't fit under. This one valve is in spec, right?

So, I need a set of feelers that can measure the minimum clearance of 0.004 on the intake valves. The 0.006 feeler won't fit under so I'm not over spec And just need to check for under spec. Right?

I'm new to this and want to proceed correctly.

 

Yes, you are correct in all of your assumptions. Slight drag on the feeler blade is okay.

HCP3445 metric Feeler Gauge Set. These gauges will work on all XJ engines EXCEPT XJ700-X and XJ750-X models, which require thinner feeler gauges to check the intake valves clearances on those models. Complete set of 3-1/4" long straight-blade feeler gauges combines all sizes from .0015" thru .035" (.038mm thru .889mm) on a handy storage ring. Sizes on the blades are listed in both decimal and metric dimensions. Includes a 2-1/2" long ruler.

Non-"X" engines have valve clearances in a range from .004" - .008" (0.110 mm - .200 mm)

Decimal Inch Sizes:
.0015", .002", .0025", .003", .004", .005", .006", .007", .008", .009", .010", and so one by .001" increments up to .026", and also .028", .030", .032", and .035".

HCP6383 metric Feeler Gauge Set. These gauges will work on all XJ700-X and XJ750-X models, which require thinner feeler gauges to check the intake valves clearances on those models. Aftermarket 32-blade metric set has 95mm long blades, hardened and polished, with the tapered ends needed to access the valves on these models. NOTE: these feeler gauges will fit perfectly, although you will have to rotate the blade 90 degrees to the holder for some of the inner valves on X-models.

Comment: the inclusion of inch measurements AND the inclusion of smaller sizes makes this set ideal for all XJ-bikes and especially for X-models.

X-engines have valve clearances in a range from .004" - .012" (0.110 mm - .300 mm)

Decimal Inch Sizes:

.001, .0015, .002, .0025, .0028, .003, .0035, .004, .005, .006, .007, .008, .009,
