Thanks for that Zman...
Out of the box my rings were at 0.25mm.
Wiseco's formula comes out at just under 0.3mm.
GasGas Workshop manual specifies minimum 0.5mm.
So based on this, I decided to split the difference and set mine at 0.4mm.
I was quite shocked when I removed my barrel and found the old ring end gap was 2.0mm.
