• 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 The previous version was outdated and no longer supported.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'm just finishing putting a new top end on my 84 500CR, and after talking with Rick Horvat, i'm thinking of going back to the 38mm Mukini
the bike had on it , instead of the 40mm.

He said the 38 will make it start easier, & has some jetting info his said
he'd dig up for me.

What's every one here running: 38mm or stock 40 or 44 :eek:

I've got a 40 on the 82.5 and I am putting a 38 on my '83 500CR. LeftCoast has all the jetting info and set-up stuff in a article in Husky Club Newsletter #32
 
I'm very interested in the carb modifications. I have two 500's, 83-XC500 and a 84 WR-500. Easier starting would be a plus and power wise? they will never be ridden to their full potental. I'm unable to find the #32 issue on the list on this site.
 
Here's info from #32 newsletter

Here's the info from Husky newsletter #32 on the 82.5 500CR of
Allen McKay

Allen's bike had metal removed from the combustion dome to lower compression & make it easier to start. (doesn't say where or how much though?!)

Other mod's are a 38mm carb Manifold (off a 250 and pushed the carb bell back too far back) was milled 6mm.

He's settings for Sea level:
380 Main Jet , 3.0 Slide , 6Dh3 Needle with clip in #1 position,
P-2 needle Jet, 35 Pilot jet, NO air jet, 50/50 VP & pump gas
with Spectro 50:1.

Note it says he's running the stock pipe with a larger aftermarket silencer ,PVL ignition & polished reed assy too.

The Stock Husky setting for the 1984 500CR (from MXaction) with 40mm are as follows:
360 Main Jet, AA5 needle jet, 7DH3 Jet needle & 35 pilot
 
You can save your $$$$ on a new carb

I am running the stock 40 on my 83 XC 500

I did build my own intake blade system to increase throttle velocity and hopefully ease starting.

it did that and more.

She lights right up and the throttle response is almost too quick, still very smooth, but she builds revs much faster than before, starts easy (start it with my left boot on the bike if it has been started that day)
and pulls hard and fast and it was about 150 cheaper than a new 38mm

YMMV
