you should never lapp a piston and sleeve. when you do this, you remove the cross hatching on the sleeve,
and ruin the fit and finish, also the cross hatching asists in allowing to oil to have better surface tension and
do it's job. it it has no cross hatching, it will be too smooth and the fuel will not work/movearound/and stick
to the piston sleeve surfaces as intended.
