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 The previous version was outdated and no longer supported.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

Compression Testing & PSI

Curious what a typical PSI reading should be on a vintage Husky using a compression tester. I just bought a tester and want to give it a try before I take the motor down and inspect it manually. I've heard numbers anywhere from 125-150LBS is a normal range. Not sure if the bike specifics matter or not, but if they do, my Husky is a 1979 250WR. Any help would be appreciated. David
 
I think it should be higher than that. My 83 250 runs about 160psi and my 430 about 180psi. But there are so many variables including altitude and how hard you kick, not to mention the gauge itself. About all you can really do is build the motor correctly and get a baseline when it's new and broken in, then watch the readings over time to help gauge when it's time for a rebuild.
 
I did some research on proceedure to confirm what I have heard about having throttle wide open during test. I did find an article supporting it so it does make sense
 
You can't push the PSI as high on an air cooled bike as you can on a water cooled, but I think there's more power hiding in those Can-Am's!!!
