Great product

Came with more than enough to do a pro circuit silencer. After installation I noticed a big improvement in power and throttle response. Very pleased!

Repack more often than not

Not much to say about this. It's a bag of packing, helps quiet down the bike and get that nice crisp sound back.

So easy to do

First time ever using this product, very easy to do and work with. Plenty to repack once- might even have enough to do again.

Meets and Exceeds Expectations

Ordered the repacking material and a top end rebuild kit on Wednesday and everything arrived well packaged on Saturday evening. After watching a brief YouTube video on how to properly repack the silencer I was finished in about 10 minutes.

After rebuilding the CR250 on Sunday the engine runs great and sounds perfect! Everything meet or exceeded my expectations.

I've used Motorsport since around 2008 and I've never been disappointed in an item I've purchased or their customer service! They have become my primary online parts store for all my dirt bike needs.

Works darn good

Well it is exhaust packing so not much to say but after I put it on my bike sounded totally different in a lot more tolerable. Notheing worse than a 2 stroke with a blown out silencer

Not enough material

Bought this for my fmf shorty and there wasn’t near enough material to repack the silencer. It was comparable to wrapping a napkin around it. Luckily the old packing was salvageable. Will not recommend.

Q: Stupid question but will 4t packing work in a 2 stroke
Over 4 years ago
Over 4 years ago
A: Yes, the 4 stroke packing is fine for use in a 2 stroke silencer, but not the other way around. Only use 4 stroke packing in a 4 stroke silencer.

A: Yes this packing will work great on any brand of 2-stroke silencer.
Over 4 years ago
A: Absolutely! You will likely have quite a bit left over. And depending on the exact size of your silencer, and how you cut it, there may be enough to repack it again when the time comes. Lucky you.

I have a FMF shorty pipe will this packing work with it?
Over 5 years ago
A: Yes it's plenty long. You will need to trim it down to fit
MotoSport Staff Expert
Over 5 years ago
A: Yes, this would perfectly with your Shorty Silencer. You will likely have extra packing since this would also work for the standard length FMF Powercore as well.
Q: I was just wondering of this came with the silicone? Thanks.

Expert MotoSport Staff

A: No. There is not silicone included with the packing. You should be able to use any High-Temp Silicone that you would find at your local hardware or auto-supply store.

Q: How to repack FMF Silencer
Over 5 years ago
MotoSport Staff
Over 5 years ago
A: First the outer can must be removed to gain access to the inner core. Typically this is done by either removing the screws or drilling the rivets(whichever your particular exhaust has) on the inlet side of the silencer. Once those are removed, you will be able to remove the outer portion or can of the silencer. You will need to remove all packing that still resides in the can and from around the core. The silencer packing comes in a large sheet and will need to be cut to length for the length of the core. After cutting the packing, you simply roll the packing up around the core snugly and reassemble the silencer. If you do a silencer repack search on youtube, there are a few that you can watch that will also help show you how to do it.
