Long shot ---- Broken Exhaust Bracket rear Header, Loose Heat Shield

Im getting the same kinda thing from the iron 883
sounds like a resonance bout the same frequency as the cylinder finds if you flick them.
Its a bit anoying

Sounds like pinging, especially if its makin that noise under load.
What tuner are you using, can you retard the timing in that range?

Try pulling 2 degrees out of the whole timing map for both cylinders and see if it goes away...

Funny thing is doesn't really do it under load on mine just cruising along at about 80 or so.
I notice it more wearing an open face helmet.
about to get TTS and dyno, so will ask my dyno guy to suss it out and let ya know.
Im not really sure what pinging sounds like so cant confirm hope it is and it can be made to go away.
another mate with an iron has the same sound going on ive got about 3k on my bike now didnt seem to do it as it was running in.
also when i was riding with a mate who has the same pipes as me i could here that both machines were making the same noise at the same revs.
as volume of a sound will sum and increase if oscillation is the same you could really hear it quite loud.
is it possible its just the sound the engine makes?

Well Skull , Does the lid have to come off ?

Is the noise coming from the front pot only?

Just a thought but the crank maybe stuffed.

I've done 2.

Yeah just got the TTS so i might try pulling out the timing degrees.
seems all the irons ive ridden with make the same noise
more noticable with stock pipes on at lower revs.
had to take em off for inspection.

dunno about the crank only got 2500 kms on the bike would have thought it would last longer than that .

hey lonerider,  yeah I pretty much am in the same mind as you.... to me it doesn't really sound like anything is wrong, rather just a normal vibration or rattle that the engine would produce.  It really doesn't bother me at all and I was never concerned about it.  

nightrider....   now that you mention it, I think I only noticed this noise when I still had my stock pipes on!  but when we went for that night ride you said you could hear it on my bike too, but i couldn't.   I don't think I have heard it once since i put on the V&H pipes! 

Hi guys,
my Sporster does the exact same thing. Dealer says just louder then
average, all ok. Just put louder pipes on it.
Bullshit i say, brand new bike and making horrible
noises.
I suppose thats what happens when u buy old American
shit technology.

maybe it"s the shit they call petrol these days, had to use garden variety unleaded to get home yesterday, and my 1200 pinged all the way.

I put a high flow AC and a the base map from tts and the noise has pretty much gone away.
very interesting/
bike runs so good now i got a speeding ticket !!!!!

I have read the responses to this noise problem and it sounds just like what I am experiencing in my recently purchased '07 Sportster 883L.  My bike was purchased only weeks ago with only 320 miles on it.  I now have about 875 miles.  The noise that I hear is a combustion related noise,  The more pressure in the cylinders, the more intense the level of the noise.  On level ground in 5th gear, cruising at 50 mph, the noise is barely perceptible.  Roll on just a little throttle and the noise (rattle) increases.  The more throttle added, the louder the noise.

I have taken the bike to 3 Harley gurus and all agree that this noise is a Harley way of life.  All have said that some of the Sportsters are noisier than others.  The fuel that I am using is 92 octane ethanol free.  I have even tried some 100 octane aviation fuel and there was no change in the noise.  It is my firm belief that this noise is not a detonation noise.

When I first got the bike, it had loud Python 3 pipes on it, slip-ons. The noise could be heard, but mostly it was masked by the loud pipes.  Now, I have put the stock mufflers back on for some kindness to my ears---and those of my neighbors.  The noise is more apparent.  This bike has been equipped with a V & H fuel pak and was supposedly tuned with the Python pipes and the Screamin Eagle air intake.

All of the "gurus" said that the noise is a normal Harley 883 noise, and to just ride it and enjoy it.  Apparently, not all of the 883s have this noise and my question is why?

I sounds like maybe it is pinging under load maybe try differant fuel . a bad flash point and pore flame propogation causes this under load if it dosent hesitate or miss it could be due to fuel or fuel air mix maybe a timing thing . ??????

GK-74

Thanks for the thought. I have already tried different fuel all the way up to aviation 100 octane and there is no difference at all. This sound is not detonation. The sound will occur even with only light throttle and the engine just lightly loaded.

 There is a 'natural' - And I use that term loosely - noise that the evo engine makes...Only way to describe it is like a fast 'ticking' that gets faster and louder under load but quietens down when cruising. If this is the noise to which you are referring, You'll learn to like it...It's impossible to completely eliminate the noise, But a good set of pipes will drown it out, To the point of barely audible.

Check the valves mate or get em checked if its a crook valve spring OUCH check this thread not pretty

hi all , my 2012 1200 iron dose it as well, 2500kms , has done it from the day i picked it up, , seems to get more noticable when hot on long ride , and very bad when useing 91 ron fuel , just a bit of pinging nothing to worry about just ignore it after a while youll not even notice it . used to get it on a turbo car i had a few years ago when i upped the psi and had a non adjustable timing , never caused any probs
