The link below has them calling the 212cc Predator 7
HP. They also seem to be a little concerned about using ZDDP because of the flat tappets. Personally I do not thing there's enough spring pressure to worry about it.
Seems that the Predator has different rods, cams, and piston/rings than the Honda GX 200 and clones. The 212 cc Predator has a 70 mm x 55mm B/S, the old engine was 68 mm x 54 mm.
