I have been told that the gaps should be:
1st ring: 0.016-0.018
2nd ring: 0.018-0.022
However, the set I have got already has 0.022 in the first. I measured the old, original Mitsubishi ring, and it gave me 0.018
What are the typical gaps you make in your racing engines?
I have read, you need to make it a bit loose: piston clearance about 0.020 and ring gaps 0.020-24
