Default Idles Weird - Why?

A file called "hog.mp3" is attached to this post.

Would someone tell me why the bike idles rough like that, please?

Plug or plugs fouling out? Just start all of a sudden?

What year and model of bike? Carbed or injected?

start with the simple things first, plugs, wires, fuel filter etc.

EDIT, OUR REPLIES MUST HAVE CROSSED.

That may be the problem ... it should have 2 cams. Sorry, couldn't resist

Have you confirmed spark at both cylinders?
Conpression test?
Bad injector?
Any codes?

Sounds good to me, my 04 RK has 510 cams and sounds very much like that.

Thanks pplz - I just bought this bike and I had to confirm - lol

The bike runs like STINK! Fastest Harley I ever sat on!

Do your bikes "load up" and even backfire through the exhaust when you give it gas from low revs and the motor is hot? I have to keep my revs up, then everything is OK. Starting from a stop I have to give it more revs then use the clutch gently...

Is this happening on your bikes? Seems a natural, given a cam that moves the power band up.

Itmay be a 96" thing. I have an 09 Road King and I noticed I have to give it more throttle when pulling out from a stop. Seems to lug a little if I don't have the revs up. Never had to do that with any of my other HDs.
