Ted told me he spent quite a bit of time up in the cut, but never found better than a 6.Had to clearance lower pin support on 461 piston to clear the cooling bridge on this saw. 462 has a cast in bridge where 661 has a removable one.
Oem 462 piston weighs 96g. Meteor 461 piston weighs 82g. After clearing for skirts and cooling bridge the modified 461 comes in at 78g.
Pretty substantial when your lookin for 1/10s in the cut.
