  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Just like title says. I have the FMF powercore usfs approved arrestor and its got about 14 months solid use. Today it was making a "crackling" noise after I shut bike off. I was like..."what the eff is that" -lol. Other than a little normal spoog that was it. Is it time or how would I know?
 
If I remove the silencer while working on the bike and it feels like it weighs 10 lbs. then I know it's oil saturated and I repack it. That hasn't been a problem since I got a Lectron carb so I'm going to defer to Mike-AK and do it when the Brraaapppp!! hurts my ears.
 
I've been going with 40-50 hours but I'm running an FMF Q Stealth (KTM 250 XC) with no spooge. My CR only has 7 hours on it but I haven't really fine tuned the jetting because of the constant weather changes lately making it almost pointless for a play bike---moderate spooge so I'll just pull it apart at 20 hours to peek at it.

I ran the same packing in a White Brothers 4T silencer for two years once and suspect that, after the packing wore out, the excess heat caused the metal fatigue and cracking of the internal ring.
