I started building a combination vertical stand for the engine that will also serve as a fixture for aligning the chain drive and allow me to safely work on the motor in the vertical attitude and to power it up on the bench. I actually have a loop frame section bent out of 1" steel tube that will be a part of this work stand. the radius matches the Sportsman loop frame dimension, though the abbreviated straight down tubes don't accurately match that frames geometry; as I didn't feel it necessary for my use as a work stand. The Sportsman frame and tank is my choice for this motor. I'm getting quite close to making some bench runs with the cased e-motor & internal drive connected. Rick C.
