Ok, I've got a Minarelli V-1 that I've just received a new piston/rings/cylinder for. My question is the arrow on the piston...does it face the intake or the exhaust?? Also, the rings are cut at an agle on the ends...I assume the bevel should go around the locating pin in the piston's ring groove...i.e. the pin is in the "upper" part of the groove so the bevel on the ring shuld have the "long" ends of the rings at the bottom of the groove. Does this sound correct????
