Default got a problem. coughing through intake. video.

here is a video of what my bike is doing, I know it is a tune problem, or atleast it started right after my tune. bike is a 09 streetbob, python staggered duals, bct qq baffles, heavy breather, 54h cams, adj push rods, 30t pulley, pcv tuner, and some other odds and ends. what is your thoughts? fyi seems to get worse the hotter it is outside, it runs great anything above 2800 to wot. it died in the end. It is getting retuned saturday.

Oh, man that's horrible! I don't know about the internal stuff you had done but I have pretty much the same bolt on stuff as you. Mine went on the dyno and doesn't miss a beat. All work done by dealer (had a discount on parts and labor). I hope you get her running right. Good luck!

Clean the idle-air controller (IAC). spray some throttle body cleaner in the hole inside and in the top of the throttle body.

Sounds Lean, a retune should straighten it up. That is assuming the valves are adjusted properly when the cams were installed.
