• Husqvarna Motorcycles Made In Sweden - About 1988 and older

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 The previous version was outdated and no longer supported.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

72-74 CR 400 pipe

Please post some photos of your 72-74 CR400 pipe. I don't care if it's stock or aftermarket, I just need some good reference photos. All angles, mounts, silencers, whatever you can post, please. I don't have a pipe for the '73 I'm building from scratch, and I'm not sure what I'm looking for. Having said that...

I need to buy one if you have one.
 
72 - 74 would be the MJ and MK frame. Here's some photos of a stock exhaust. Sorry but I don't have one for sale. If you want measurements or more photos just let me know, more than happy to help out.

Tip: You can build a 400 header pipe out of automotive exhaust material. 2-3/8 O.D. X .0625 wall mild steel. Purchase a 180 degree U shape with a 5" CLR (clear line radius) aka 10" center to center radius. NOTE: The 450's from the MJ and MK frame era require the 9" radius, 8" can work if 9" is not available. The U pipe will need to be cut and re-welded near the center. Best way to find the correct position is to set in up on the bike before tacking it into place.

For the exhaust manifold mount use a 1-1/4" long piece of 2.25 O.D. X .095 wall mild steel exhaust tubing. It will slide inside the header pipe and over the manifold with a little persuading.

Here's an example of a 450 application, virtually the same as the 400.

Wow. That's such great info. Thanks so much. I have some left side pipes that are "not 400" but don't know what they are other than that. They won't fit the exhaust flange and clear the 400 head. I'm trying not to cut them up because they are usable on the right bike.
