The big brown truck dropped off a nice set of EPCO SS mufflers last month. Of course, they got installed right away. No other mods - took it for a spin. No deceleration popping on the road, but blipping the throttle in neutral produced a fair amount of "cackle". Throttle response was slightly improved, and the mufflers sounded great.

Two days later, my son was moving the Road King around to get to HIS bike and dumped it over on Mr. Speedy. Well, I had the fender repaired and repainted (nice job) at the local body shop and got it back today.

In the mean time, I removed the snorkel, the air injection system, and installed a K&N filter. Also, SS clamps and SS allen-head bolts for the carb bowls. Left the factory needles and purchased one of those little D-tools to do the adjustments.

Factory pilots, 130 mains, needles are 2 1/2 turns out, no shims. Have not sync'd the carbs yet.

Did about 35 miles today on the completed setup.

Does not "cackle" anymore in neutral when you blip the throttle. No deceleration popping. None. VERY improved throttle response. Probably my imagination, but I think it's louder now, also. What a BLAST !!!

My wife wants to know if that grin is permanent. :-D

What shall I tell her? :lgh:

The other other KevinTell her you are sorry for leaving the AI on so long. Sounds like now I have to airbox/rejet. Darn.

Well, I don't know if you need to rejet..... if you haven't changed the airbox or filter. There are two parts to the equation - one is opening up the exhaust and the other is improving the air flow. With only the muffler change, this one ran well and had no deceleration popping. I hadn't changed the airbox just yet nor removed the air injection..... You would have to put a few miles on it and check the spark plugs to see if it's running lean. With just the initial muffler change, mine ran just fine with no flat spots and had improved acceleration. Just that pesky cackling when blipping the throttle in neutral. Not really objectionable - sounded cool.
