Mine is the newer model Saito (actually I've got two 56's one in silver and one black/gold). I'm afraid I'm not experienced enough with engines to go removing parts I can't even name! Obviously, a different style engine mount could help but I'm a bit limited here in Japan.

Also on the topic of engine mounting and radial cowls, how do you deal with the center offset caused by side and down thrust? How do you go about figuring out how much you need to relocated the mount to compensate?
