  • 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 The previous version was outdated and no longer supported.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!

Twin Air Filter Decomposing

My 310 has been sitting the last few years and only been ridden 4-5 times in that time. I think I put this new air filter in 3 years ago and was twin air green eco formula oil.

You can see in the image my filter is now brown. I removed it this afternoon and it crumbled in my hands but was just a gooey mess. Is this simply what happens to old, oiled foam filters?

Just glad I didn't go off motoring with a leaking petcock and a clogged filter's gooey bits ready to get sucked into the engine.

In any case Bill's saved the day again and has a left side petcock coming my way.

Sidenote: Do you use the mesh screen behind the filter? I was considering removing mine, but ended up glueing it in place for a permanent seal :D

Thanks all. Picked up a can of Maxima Fab 1 spray for the TA filter I had waiting. I do use the backfire screen.

All back together and she fired right up with alacrity.

I've seen a lot of decomposed filters on old vintage bikes but I'm sure some of them had been sitting for decades. To have a foam filter falling apart after 3 years doesn't seem normal. Its a good thing you're the type to do preventative maintenance. What a mess that decomposed filter and the dirt that would have followed would have done to your engine.
