Local rider has run a Shovel in a 57 straight leg frame for ever. i never thought about it before but he has a tin primary on that looks great. Since all Shovels were electric start from the factory and that would require the use of a cast primary how would any of you go about running a stamped primary? I already thought about the Pan bottom with a Shovel top idea. Somehow that doesn't seem quite right for this bike. I could be wrong. It is an early flat side motor but seems to me some of those still look beter than the "nose cone" motors that came later. Thanks in advance. I am sure some one here will know.
