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 The previous version was outdated and no longer supported.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

Could a 87 430 L/C cylinder & piston bolt on to a 86 400.

Does this sound like an easy swap?
Is the the sleeve that much larger that is does not slip into the cases.

Thanks.

Does the 400 head work on a 430?
Just wondering if the stamped 430 head is different CC volume than 400?

From what I have seen and it is only two 400 heads the earlier ones have a cast in number and are higher compression while the later ones seem to be 430 heads just not stamped as such. I would say an 86 is later but my sample is small and all obtained used.
 
I wonder now what the vibration factor would be like, more or less?
2premo is there more, due to a heavier piston.
Or do they keep pistons weights the same between 400 & 430 and not rebalance the cranks.

Higher compression in high altitude might be ok, i think with my thin air where i am.


Thanks guys!
 
the 430 will likely vibrate a tad more but much of the swede vibration is in whether the crank is balanced or not it seems. my 400 is really really smooth and rev happy.
 
the reason these existed was competition, don't think they were too concerned about the vibration
the owners manual said to do major work after 8 hours, pull the top end etc.
back to the 400 430 question the cranks are the same part so if the piston is a bit heavier, well, shake your booty
 
Some of that stuff looked or looks pretty good. I got frustrated searching husky parts years ago but going sellers other items was kind of tempting on a few. I left the guy alone on the primary drive clutch but he didn't go strong enough. That is still first size. If you intend on using the piston look carefully at the wristpin bore as the standard shift ones seem to get egged out in the up down direction. The earlier 420/430 design had a longer wristpin.
