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 The previous version was outdated and no longer supported.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

88 WR 250 Exhaust Repacking

B Class
The bike shown in my avatar has a stock silencer fitted with a spark arrestor. Husqvarna appeared to do a short version and a long version judging from the parts catalogue. Mine has the short version.

Inside the silencer is a primary stage (about half of the length) which is the conventional perforated tube and fibre packing. (renewed the packing here) the second stage is similar but the pipe is not perforated (didn't repack this part) finally there is a spark arrestor jubilee clipped to the end (cant get this off)

The bike is a bit noisy - any idea's.
 
Bin everything inside the silencer and use some new perforated tube from end to end! The Enduro baffle tubes were tapered, which is tricky - I would just use a peice of 1-1/4'' baffle tube and braze a ring on the end cap inside to accept it... This will work fine and be reasonably quiet if you pack it properly - and you will get a bit more 'go'...

Any pics of this? Sounds like a quick mod
 
I gutted the muffler completely so I had a hollow pipe with the end on it to mate with the exhaust pipe. I then got the bit of baffle and had ol mate cut off the tube from the ring and then he welded a longer perforated tube to the ring part and that sits just inside the end of the muffler. then I got the spark arrestor, pulled it to bits and reversed the outer cone which slips inside the end of the pipe, over the ring of the perforated tube and a couple of tech screws holds it together. I wound a heap of steel wool around it and jammed it all in. works ok. looks a bit second hand.....I added a short piece of pipe to the end and angled it down at 45 degrees like the old kdx mufflers, just took a bit more bark off the sound than a straight end piece
 
So , On a 79 wr factory spark arrestor at the end piece where the perforated cone is just before the end cap. Is this small area insulated or not ?
 
it wasn't on the 400, only the first 1/2 was insulated, then a spring thingy and the spiral arrestor in the end. California bike... aussie bikes had full perforated core mufflers
