    I never post as I hate to hassle but the suggestions on here all suggest the entry end of the silencer slips off with some effort after removing the 8mm nuts .

    I’m great at wrench handing motorcycles but can’t get the intake end to budge without me destroying it. Am I correct to assume the rivets drilled out to remove the packing are the countersunk circles I can see on the intake end after unbolted ? Then rivet it again after repacking with some suitable JB weld or permatex if you wreck the O-ring ? All my 4T huskies were easy. Thing thing is Nuts.

    Thanks for any help.

    Yes, you will need to drill out the rivets. Be sure to use steel rivets when you reassemble. I started saving up for a FMF replacement right away, after repacking my OEM muffler on the WR300.

    Awesome. Thanks for the help. I thought it was a different silencer until I saw the faint raised paint circles

    I've always had to use a thin table knive with a nice rounded handle/end to separate the sealant between the can and the end cap. Spray a little furniture polish in the gap... Endust is my favorite, really cuts the spooge and gunk.:oldman:
