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 The previous version was outdated and no longer supported.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

I used these decades ago in my husqvarna 38mm & 40mm million carbs. It's snow mobile technology. www.thunderproducts.com/_u_f_o.htm

You have to try this. I used lower sized jets and the husqvarna being vintage as they were beat the newer bikes in response and down the straights.
 
It greatly improves the throttle responce. It makes the round slide carbs feel like a flat side.
 
Some of the Kawasaki dirt bikes last round slide Mikuni carbs had the slides built to function like this. In 1988, the KDX 200 C3 came with a flat slide style Keihin on it, but the 86-87 C1 and C2 had a "solid" bottom round slide.
 
I've got one in my 125 Hodaka and the results are awesome. The response is great.
I tried there 38mm version for my 390, and it didn't sit in the base of the carb right and kept the slide partially raised so I had to turf it. Great product tho!
 
I use a dremel tool to fit the UFO a tad better. I kind of ramp it more. I do a vee shape around the needle area.

It make the flow of the mix more even while headed to the reeds. There are no vertical walls to make the mix turn backwards. It's a straight path to the reeds. You may have to lower the jets in the carb.
 
I have one in the 38mm Mikuni VM on my 83 KX250. Running a much smaller pilot jet and slightly smaller main as a result. Throttle response is about 10%-15% better, but not as good as a well jetted PWK I'd say. Not sure how it compares to a TMX.
