Just thinking
Hi - I was just reading your posts since I ride the same bike.
I have always been inclined to keep the valve clearances towards the upper limit (ie. wider)
If you make them too tight then you don't allow for thermal expansion.
There is the chance that when the engine gets hot, and the clearances get taken up, you might perhaps end up holding the valve open a little fraction.
This in turn would let hot gasses past the seat and valve face burning these and destroying the good seal.
Mine are set at 0.15mm for the inlets and 0.2mm for the exhausts. And no rattly noise.
