Default Horrible Noise Coming From Bike

Hi Guys, I need some advice please. I have just had my bike in at HD getting some work done. It had stage 1 with Swept Pipes with stock baffles and K&N filter.

I had the RPW Baffles installed and the Lloydz timing wheel set to 4+ as well.

I took it for a 30 minute ride the first night back and it ran perfectly and sounded amazing. Couldn't have been happier. Not sure if my neighbours would agree though as it now sounds a lot tougher than stock baffles.

I went out today to ride to work and it kicked over fine, idled fine for a couple of minutes to warm up. I then rode off to work and about 2 minutes in it started making a really bad noise when I let go of the throttle. It sounds like (and this is going to be a crap description) a wood pecker banging on the exhaust like dak-a-dak-a-dak-a-dak-a-dak. It stops instantly as soon as i even give it 1mm of throttle. It sounds horrible.

I don't think it's pinging as it is an exhaust noise and not coming from the engine. I can ride it smooth as all through the gears and rev it right out as well and no bad noise. It is purely when I totally release the throttle.

I thought it could be backfiring but it is not a banging noise like a gun going off.

I aslo gave them Lloyds Exhaust gaskets as well to make sure it was not going to leak anywhere.

I have also unplugged the 02's as well and used WitchDoctors plugs for them.

I was thinking it might just need a tune now as the increased Airflow of the new baffles could be letting fuel through or not enough etc. but if that was the case then why was it running perfectly on the last ride and then it showed up on this ride?

Theoretically if it was a fuelling/mapping issue from my mods then it should have been having this issue then right?

The Bike is always run on the highest grade fuel as well. 97 Octane in the UK.


If anyone can shed some light that would be great. I will try and get a video of it but it will be hard to do as I need to ride it and get someone to film it.

Hear from you soon! HELP!

if possible, the best thing you can do is get a video of what you're talking about.

[Edit] I just saw the last part about having someone film that for you.

Deleted the comment.

Sorry, Re-read the first post. I thought you meant it was the bike that stopped rather than the noise when you let off the throttle.

I'm thinking the baffle too now. It would explain why it has only started today and not on the first ride. It would also explain why the noise is only there at closed throttle and any revs it goes away. I think the more airflow keeps it in place.

I don't think it the wheel as it runs perfectly at revs and is coming from the exhaust.
