Ok thanks Grumpy.
To start with I did some conversions to mm�s as this is the measurement unit of my feeler guage
Inlet .005-.007 inch = .13mm - .18mm
Exhaust .009-.011 inch = .23mm-.28mm
At no point during the measuring process could I get a .10 feeler gauge through the top of the tappet and the bottom of the valve spring for the inlet measurement
.20mm fits through for the exhaust measurement however .25mm does not.
I triple checked the measurements to make sure I got the same results.
Regarding the breather disk. From your example I should only be able to fit a 1.1mm feeler gauge through the gap however the gap is much larger unless I am taking the measurement incorrectly.
I have placed some photo�s below as I hope others can learn from this example as well.
