I have an excellent condition Victory that intermittently melts the drop bank coil on the upper PF. I have replaced it twice now and a 3rd is on the way. I suspected the lugs on the coil were getting shorted as all that stuff is jammed in pretty tight up there so I was careful to shield the lugs when I reseated the upper pf. I'm still not convinced that isn't the issue but looking for some experience here. I wouldnt think the driver transistor would be intermittent but looking for ideas.
