As I finish up my 2 stroke jackshaft kits, I am ready to move on to designing one for the 4 stroke. For those of you who have, or have seen, multiple 4 stroke kits and mounting plates, how similar are the engine mounting holes between the Honda, Huasheng, Titan, etc? My initial thought is to use the engine mounting holes to mount the bearing plates for the jackshaft but I need to know that they are all the same or at least close. I have one kit that a friend let me borrow. Would like to know how similar it is to the rest.
