Hi there!
I bought a FMF quiet core insert (040630) for my Powercore4 muffler.
The thing is that the hole in the new insert, were the allen screw goes through, does not align with the screw hole in the muffler. Looks like the thin inner pipe in the muffler that holds the hole has gone like 5-8 mm into the muffler itself (picture).
If you look at the old spark arrestor you can see how "stretched" and oval the hole is, to be able to reach the screw hole in the muffler.
Anyone who has seen it before?
I thinking of taking the muffler apart and see if I can bang the inner pipe in place to align with the new insert's hole.
Any other suggestions? :)
