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 The previous version was outdated and no longer supported.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

Here's what I did, done a couple sets of them for the 630s, 610 has the same internals I believe.

The stainless muffler will slide out of the aluminum case with some tapping once you drill out the rivets on both ends. You may have to slide it out a bit, cut off the end cap, and then pull the rest out the front if the insulation between the stainless and the aluminum binds up.

With the endcaps chopped off, you can replace the center core with some perforated tubing and wrap it in muffler packing, then rivet it all back together.

I went one step further and opened up the endcap exits and welded in some short tubes to center the perforated tube.

If you still have an O2 sensor, you haven't done the power-up, which is the FIRST thing you should do, even before gutting the exhaust.

It eliminates the O2 sensor and replaces it with a brass plug and a resistor plug in the harness.

You will use more fuel, but that is because the bike will be running richer, as it should be.
