Powercore Insert

Bought this as a replacement for the one I lost that came with my powercore 4 slip on. It fits but not as snug as I'd like it to be but gets the job done with passing ama inspections at local races. I may try using some high temp silicone grease or something to see if I can seal it better.

Doesn't fit well.

I bought this because my Powercore 4 silencer needed a spark arrestor for riding at parks. The actual item is really well made, but it doesn't fit well on my bike. The bolt does not seem to tighten all the way down and what I end up getting is a really loose spark arrestor. Maybe I just need a longer bolt. But so far, it sucks.

Do I need to get this and the fmf 4.1 s/a too? for a dual exhaust 2006 crf250r with the fmf 4.1?
on the fmf 4.1 spark arrestor page it says I need this part to make it fit. I'm not sure if I need just this or both of the s/a.

To better assist you in answering this question, I was able to get a response directly from FMF Racing.

"Thank you for your interest we appreciate your business. Currently we do not offer a dual set up for the 2006 CRF250R but we do offer a single muffler that will work with the stock or FMF header. This muffler will come with a quiet core spark arrestor insert. If you purchased a dual muffler for this model it will not come with an insert but we do offer inserts that will work in the smaller canister. Since the dual canisters are smaller they will use a smaller insert. For any further questions please contact us at the number below or via email."

This is the incorrect spark arrestor for the fmf 4.1 exhaust. Here's the link to the correct part: http://www.motosport.com/dirtbike/product/FMF-FACTORY-41-SPARK-ARRESTOR-INSERT/?catalogId=102323

this will not lower the sound of the bike by much.

FMF offers a few different spark arrestors for the powercore 4. Take a look at this fmf page to see which powercore 4 you have:

this spark arrestor insert only fits the FMF titanium powercore exhaust systems. the only spark arrestor end caps that will work with stock exhaust we carry, is the ProMoto Billet.

This is designed for FMF silencers. You might be able to make it work but I wouldn't recommend it.

Your supposed to use your stock cap, we only sell the screen so you will have to drill the rivets out holding the end cap on then replace the screen and re rivet it back together.
