Today I have taken the top end off my S2 project. All 3 pistons have approx 5mm removed off the back skirt.
Why are they ok to re-use

give the barrels and heads a bit of scrutiny simon, see if any mods done there, smoothing of the ports head squish etc, was the base gasket normal ?,
as usually other mods that go along with a cut piston skirt,
see if its been upjetted from standard, just curious,
