Watch she doesn't lick it raw... my aunt border collie had a cut on his foot, and wouldn't stop licking it raw... she had to put baby socks on it to hold the dressing so he wouldn't lick it and make it worse.
we use a product called bag balm on horse insect bites, (haven't had one on harley)
BagBalm - Canada not sure if it's available in US or not, but here you can buy it at walmart or any pharmacy.
