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 The previous version was outdated and no longer supported.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

CR250 to 390 Swap?

What are you trying to do here, turn your 250 into a 390? or do you just want to know if the 390 cylinder will bolt up to the cases? What year 390 top end ? The 390 has a longer stroke than the 250 so if your looking to build a 390 you may as well start with one to begin with as a core engine might be cheaper to buy than a rod kit. I was going to build a 250cc engine to stick in my 77 390CR that way I could race one bike in two different classes with a quick engine change but never could find any 2959 engine cases so I gave up on that idea.
 
I have a 2065 Bottom end I was planning on rebuilding. So I am buying a rod kit anyway. I don't have a 390 top end so I would have to find one that would fit.

I'm intrigued by the idea.
 
Ok so your going to build one. I have a 77 390 cylinder sitting on the bench I can see if if the bolt spacing is the same and check it to a 2042 engine.
 
the bolt spacing is the same.
however,, the head, rod, bearings, pipe, ect, are all different...
it might be easier to just buy a used 390 engine... and find a good used pipe as well.
