Hello, I just found your thread and am looking on in earnest. Many years ago I hit a deer with my Nighthawk ( and unlike others I did not cut the deer in half and keep going). I was wondering if you are going to change the cam timing or switch to a K&N filter with carb adjustments. I saw an old article somewhere on the internet that I can no longer find that described the whole process. I am intending to replace the head with an new one because of some broken fins. I've gotten to the point where the bike is actually referred to as a classic and it would be nice to get rid of the unsightly scars.
Good luck on the rebuild and I will be following
