One crusty pie is the correct term. For max thrust the magnets need to be just under the surface of the tyre tread, this is closer than most. This winding was corroded when it was run for 6 months as a sealed standard motor. The whole winding has been dipped in a product called Nyalic which is good to 350F but some of that has darkened. Riding with dirt bikes is very dusty.
