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 The previous version was outdated and no longer supported.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

New Bike: 1974 Husky 400 WR

Hi. I just picked up this bike, and have a few questions. Hopefully some folks are familiar with these bikes.
1. The bike has a piece missing on the crankcase around the rear chain drive sprocket. Are the cases magnesium? I have a spare mag cover I was thinking of using as a donor for welding, and wondered if they are also made of magnesium?
2. I would like to change the spark plug wire coming out of the coil. Does the plug wire screw in style to the coil, or is it not possible to remove the wire and replace it with a new plug wire?
3. I was hoping to find an electronic copy of the owner's manual, but so far, no luck. Does anybody have a copy, or know of a source?

Thanks,
Stephen Hill

Stephen: I've got my original 1974 400WR Owner's Manual; I'd be delighted to scan it for you. But, it lacks some of the detail you need. I'm working on the magneto and wires myself (FEMSA unit). The manual does not have a wiring diagram. There are 3 outputs from the mag to the downtube - red, yellow, green. I found an '82 360 diagram that says "yellow is hi-output for headlight; green is lo-output for tailight" - that would indicate that red is hot to the under-tank coil for the ignition, but I'd sure like to confirm that. I'm getting spark at the points, but nothing to the plug as yet. I'll test for continuity next.

I've often seen the countershaft sprocket cover off similar bikes, I've never had a problem with the bike throwing a chain, but I'd guess it's there to keep out crud and protect your leg. I saw one on eBay at one time.
 
I am pretty sure the big case engines used aluminum cases. Mostly because Husqvarna made a big deal of it when the 250 MAG came out in 1974 :)
 
Stephen, i'm starting a restoration on my 74 400WR myself. I bought it in 75 from the original owner; been carrying it around ever since.

Anyway mine has a Femsa mag and a Bosch coil. The plug wire screws onto a post centered in the coil socket. The plug wire on mine was/is stranded copper core "Bumblebee" 7mm dia. wire. I just ordered some from an Ebay seller. Now I need to find a new 7mm rubber boot for the coil end and a rubber screw-on plug cap.

Hope this helps.
