Hello all
I have a 2015 roadglide special
I have installed a agitator breather,I mostly have the radio cranked on it,but today I turned the radio off and noticed noise on the right side that seems to be coming from the breather area,
Best I can describe it is a rattling sorta valve train noise

I can muffle it some by putting my leg next to the breather
Does not do it at all at idle,only under some load

Has anyone else noticed this with an open type breather

Thanks for input

 

I had a Ness Big Sucker on my '15 Limited, & had to take it off for the same reason. The noise is intake reversion.... sounds like a little guy in there tapping on a wooden drum. Cams make it worse, at least the 57s that I put in mine.

I went back to the stock housing with a K&N filter, didn't notice any seat of the pants difference.

I had a loud tapping noise coming from the throttle body after installing a new exhaust. The tapping noise wasn't there with the stock exhaust. I was told by a few dealers and a well know tunes here that some throttle bodies are louder than others and to live with it. It would knock loud at idle but go away when riding. I ended up hating the new exhaust. I got a great deal from a member here on a pro pipe which I really like. After installing the pro pipe the knocking noise coming from the T B that I was experiencing is gone and hasn't made a sound sense.

 

the stock air cleaner is made ...to control noise emissions

when we remove the muffling of the stock plastic backing plate etc and or the football cover- we hear the intake

you may hear a rattle or tapping which is the throttle plate reacting to the pulses of the valves opening and closing, and the changes in the air moving in response.

these pulses can be altered by changes in the exhaust tract
