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 The previous version was outdated and no longer supported.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

1978 250CR Jetting Question

I'm running the stock 38mm Mikuni on my 78 250CR and I'm looking for some jetting advice. I ran the bike with this jetting at Glen Helen (1,000ft Elev and 98F).

Needle: 6DH3 (one slot from the top)
Needle Jet: 166-Q8
Pilot: 45
Main Jet: 430

It seemed fat all around, but I sacrificed power for longevity (quite a few seizures that day).

I'm taking her to a race that will be 4,500ft Elevation and around 95F. I've moved the clip up to the top notch on the needle and gone to a 410 main jet as a start and will do a plug run after practice. Anyone have experience with the 38mm Mikuni at higher altitudes? Thanks for any help offered!

Race Report: The top end performance was good, but there weren't any long starightaways. It still felt a little rich bewteen 1/4 and 1/2 throttle (where i spent most of my time). Since the clip in in the top position I think maybe I need to carry another needle jet with me. Should I go to a Q6 or a Q4?

I see that one of the Husky Bulletins says to switch to the 166-R2 needle jet on the 1979 250CR. Aren't the motors the same on the 78-79 250CRs? I'm wondering if this would help my 78's jetting? I'm thinking maybe there are some differences otherwise they would have listed both years for the change. ???
