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 The previous version was outdated and no longer supported.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

Do I need to vent it up under the side panel like it came from the factory or can I vent it down with the carb lines.
 
You can vent it anywhere. I don't like to leave the end of the hose 'up', though, because then anything can run down the hose and get into the motor. That's bad on the trail and could be worse when you wash your bike.

On bikes like these, where the vent is on one side and the chain is on the other, I like to run the hose up over the carb and down the other side, with the end right over the chain. It's a convenient arc... and an automatic chain oiler if any gets blown out of there. You can usually route it along the frame rails and it looks nice and clean that way.

That is a cool idea too. Probably works better to oil the chain than my leaking countershaft seal. Here's another idea; a previous owner of my WR drilled a hole in the airbox, about midway to top on the left side, and inserted the breather hose into the airbox to keep it out of harms way. The downside is that the open hose end still points up so I guess the potential for something to enter the hose is still there, like water when the bike is washed (or swamped). There really should be a 90 or 180 degree fitting of some sort on the airbox wall for this to be a good fix though. One of those things I will eventually get to....
 
"Trickest" setup I've seen was a guy who used the stainless steel braided hose and all the fancy fittings. He put a bulkhead connector through the front wall of the air box next to the carb with a 90 degree elbow on each side. The outside was plumbed to the crankcase vent and inside the box was a very cool little K&N style filter/breather hanging down: Vented, filtered, covered, AND pointing down!!

Ya Babay!
 
Something to think about....
As the bike warms up it'll spit stuff out. When it cools it will suck a little stuff in.. Not much admittedly but some... Put it wherever you like but maybe put a little filter on the end?? Just a cheapy auto one or something? The big up and then down to 'lube' the chain does a similar thing. Goose neck and all that.... remember the biology experiments at High school???
