Randii, terminology aside, I can see what you mean about the length of the torque "levers", pivoting closer to the crank versus further away. Reason I did it like this was to copy the stock configuration. The stock motor bracket arm thing is creating almost the same size lever as I am building, with the motor mount being just as far away. Actually, the stock cast steel or cast iron motor brackets are longer than what I am building. I'm not disagreeing with you about pivot point location but I am sure it will work this way also.

If I mount the mm this way I think I can avoid the problem with the shear forces.



My 2 questions are:

1: Can I weld in 3/8" steel sprinkler pipe as a bolt sleeve and will it weaken the frame to sleeve it like this?

2: Any tips on making the motor bracket sturdier? Some have suggested it needs more beef. The S-shaped gusset is so I have access to the bolts. The stock mount is not that much beefier looking. (cast steel I think)
