rse reed valve drill holes in piston or raise the piston skirt and extend intake port

yes, hole piston so that the intake is never or almost never closed. see my pages which detail how I did it on mine
 
Piston must have large to medium sized circle shape, square, or oval in the entire intake side of piston. Skirt should still remain for a total of 3mm under intake hole.
Works great!
