I have a 2001 X1 FI, I bought a muffler repack kit for the Buell Pro or Race Series Muffler. After taking out the rivets I saw the can was empty minus a few flakes. I'm not the original owner and had wondered if the previous owner removed the packing or if it just blew out.

I have seen in four stroke that not having the packing can be torque robbing if I'm not mistaken.

I guess what I'm getting at has anyone found this bike to perform better without the packing? should I not repack it?
I know sufficient back pressure is needed to have max acceleration or torque.

I'm interested in what you guys have seen

Also new to the forum, thanks ahead a time, I live in NH, married, kids, house. You know the rest.

The packing likely blew out. Packing from the factory might last 2000 miles if you're lucky.

Do the right thing and get it repacked - there's far too many squids already... no use adding yourself to the list.

Packing will make it sound a lot better too. You still get the deep rumble minus a lot of high frequency crap.

My V&H SS2R was also missing the packing (and the baffle) when I bought my bike. I guess the previous owner must have liked the sound (louder without the packing/baffle). The bike was running lean so I got the packing/baffle. It not only sounds better now (deeper rumble) but it also has a little stronger low/mid-range torque. The V&H guy told me that these bikes like some back-pressure and I agree.

How often should you repack the muffler?

According to the V&H tech guy, it depends on how you ride but generally between 5000-6000 miles. The change in the sound of the exhaust is usually a good indicator
