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 The previous version was outdated and no longer supported.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

40mm carb on a '80 cr390

I purchased a brand new 40mm round slide, the c&r500 air box grommet. I fabricated and modified the intake side adapting the 83 cr 500 grommet to the reed housing.
I changed the needle jet tube and carefully jetted the 40mm carb to the cr 390. You want to talk about the "hit" when you wick-it? What a wild ride it was.
Too bad I ended up selling it. The first guy who purchased it got injured on it. The 390cr was a fast bike anyway.

I wonder how the 40mm carb would work on a ported 250?

I built a '85 Honda 125cr I ported it and changed the port timing with the added roost boost increased voltage on the coil. She was beating the 250's but I couldn't keep it together. As I had more experience later on after we sold the bike it needed more fuel. It needed a 38mm carb. I realized this when I seen the 38mm carb on the 125 husky.
Porting, tuning, carburetor cfm/jetting along with the correct tuned pipe all goes together.
