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 The previous version was outdated and no longer supported.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

WR 500 / 1984 carb-jetting Mikuni VM 40

It depends on where you live and your mix ratio. First do you have any experience in jetting?

Make sure your float lever is set correctly.
Make sure the air cleaner is clean and lubed.
Check the rubber boots for cracks replace when necessary.
Set the needle in the third clip.
Second make sure your needle and seat isn't leaking(when the bike is off with the fuel on, flooding)
When your pilot jet is correct the balance screw should be between 1/2 to 1 1/2 turns from bottom.
Lower the idle screw as you go.
With your main jet I'd go rich till blurry then back off smaller till it cleans up.
Then adjust your needle up then down till the throttle feels smooth.
Last adjust your balance screw to tweek it in.
If it's still rich 1/3 rd of the way and up you may need a leaner needle jet. That's the verticle tube in the carb body that holds the main jet.

Sometimes going through this jetting process may take two or more times to get it right. Depending on how far it's off.
