What's not to like ? ANY engine with a Sachs crank and cylinder is good....The only difference is the machined case and mount.....
FWIW..I talked the the manufacturer of my racing twin today, he said the stiffer the mount the better it is for the engine...Quickee and Formula 1 racers go to great lengths to make the mounts as stiff as possible, stiffer mounts seem to make more rpm...Defense rests
