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 The previous version was outdated and no longer supported.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

Beaware of used cylinders.

When buying cylinders and heads on eBay. I see miss dated cylinders. Look at the location of the studs. Some later cylinders have the studs against the sealing ring. The older cylinders have the studs away from the sealing ring.
Some are dated wrong. Make sure you match up your cylinder to the one pictured. Check and double check.
 
Are you specifically speaking of the stud difference between the 1979 and 1980 390 cylinders? I am not sure if the difference occurred in the lower displacement models as well. Since I have never owned a non primary kick 250 as of yet.
 
In the early years the studs were closer together with smaller transfer ports. Then they opened up the dimensions on the studs and increased the length of the transfer ports. In 82 they increased the transfer ports again size wise on the air cooled. This was kept the same into the liquid cooled engines. I'm not sure about in the late 70's as to what interchanges but you need to checkout the stud locations and the transfer ports. One of the Husqvarna parts sellers has pictures of the base gasket shown. I noticed the missed marked year wise cylinders on eBay.

Look closely at the base gaskets and the size of the transfer ports.
