The Dyna has proven itself to be easily tuned to. Cheap, readily available, and good looking,nice sound..
First thing to check out is leaks. The header bolts are notorious for getting loose. And, you can shaft yourself wonderfully by trying to tighten it up, so it's never gonna leak again.
Adjust cold, one hand, thumb on the end by the nut, rotate by closing fingers. Don't involve the arm muscles. Feel of it. I used antisieze there. I'd rather hafta check it and adjust than watch it rust or twist it off.
When you go to swap out the muffler, remove the whole exhaust system and then wrestle the old one off the header.
Gotta be careful about those skinny little studs in the head.
That header and Dyna offer might be good.
How old is the Dyna? Miles run?

I'm NOT gonna do it, ohhh, but the Temptation is great.
You have been around long enough to know better than leave such low hanging fruit right in front of me. I've already taken a cheap shot at Art, so, my appetite is satisfied for now.

Never exceed 3 turns out on the pilot screw.  Beyond that you cannot be sure it will not vibrate loose.  Once you get past 2 turns out you need a larger pilot jet, then go through the tuning process again starting at 1 turn out.
