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 The previous version was outdated and no longer supported.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

head compatability

One way is to see if the cylinder base gasket is the same part#.
For instance it is the same for the earlier non-primary kickstart 250/390.
Just go to Hall's Cycles online parts books.
 
You can make a case for the 430 by cutting out the metal which makes the crank cavity smaller. Yes sure the the main four long ones will be in the same spot but I can't say about what they call the head screws as I don't have a 250 head.

Add later,

Well from the parts sheets it looks like the 81 250 has an ealier kind of cases but basically once the cases look the same it is a web in the crank cavity as best as I examine the parts.

The 420 head has much less volume and is designed for the same piston diameter. The other 420 one has th plug exactly centered. It sure looks to me like a 500 head so long as it isn't the 84 or last air cooled version would bolt on with no mods. I suppose most of the guys here are racing tracks not slamming through rock gardens and wouldn't want to go that way.

Yes i was thinking if my current head mod doesnt work out that a 250 would give me more material to work with.
Huskydoggg,Thanks for the pictures for us visual males.
Like Schimm says a picture is worth a thousand words.
 
Highdez,
If you want a 250 head to use, I have a good donor. A PO ground some material off the front edge (or back, depending on which way it's installed). You can have it for the cost of shipping from NorCal.
