I am in the midst of building a Hog Bipe and chose the Saito 100. It was down to an OS91 surpass, or the Saito, and I chose the Saito because I wanted the Golden Knight version. If you want to see how it is going, I am doing the Hog Bipe build thread in the kit forum. You will probably run into the problems that I have and find the the carb/needle valve will need reversing. This puts the throttle cable in the center of the fuse, but it can be set up that way. You can PM me if you end up choosing the Saito and I can take pics of the install if you need.
