So there are several ways to run this thing. I turned the bearing carriers down to the size of the 2" tube. Once the chainline is figured out, I will plug weld this into the bottom bracket. The pic above is what the setup would look like if I ran the chain on the left side of the bike. Since I don't have the Worksman wheels here, I can't determine the chainline for spacers but it is pretty close to where it would be. If I bought their 3/4" bearing wheels (with .125 inch hub material), requested by the guys making early auto replicas (http://www.smallcarplans.com), I could make my own sprocket carrier for the left side BUT there would be no brakes. I am planning on a rear drum and brakeless front. Since I don't know how robust their sprocket mounting configuration is, and since the drum will be fixed on the left side, I will likely run the chain down the drive side. I would rather have the pulley and driven gear on the same side of the bike so that the opposing forces will not twist the frame as much under torque. More about that as I get to it. Here I am cutting off some of the fins on the flywheel. They are a definite hazard turning 3000 RPM right in front of one's right shin. A small guard should be easy to fashion around the thinned flywheel. After this I will clean it up on the mill. I will leave some material there, not because there is any cooling effect (without all the shrouds), but because the engine needs the weight. Since I'm adding the clutch to the other end of the crankshaft, I'm hoping I will offset the weight reduction enough that I don't lose too much torque or create starting problems.
