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 The previous version was outdated and no longer supported.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

40mm fork seals?

http://www.cafehusky.com/threads/1-of-5.35165/page-13

15w oil to start out with at 430cc.

Tear your forks apart and clean all inside well. Check your top out plastic washers to see if they are all mangled, broke, etc.... You can get those from Phil at Husqvarna-parts.com for 40mm forks.
Also, put new air valves in top.

Seal size is 40mm ID x 52 OD x 7,8,9mm thick.
 
Or you can use Kawasaki 80's 1000 eliminator street bike fork seals, i've used them for years.

I use 1984-85 Honda XL350R fork seals which are 39x52x11, one per leg. They are hard to get the tube in the seal because they are 1mm smaller ID than the stock ones, but they dont leak.
 
Don't forget to pre lube any seal during the assembly.

Even on the rear wheel seals and engine crank seals pre lube them.

Sorry for the refresher on pre lubing seals. Sometimes we find ourselves in a rush. I was when I was younger now I'm old and slow but I'm fast on wicking it.
 
Phil at Husqvarnaparts has the best leakproof seals ive ever used, 3 years on the 400 and just the tiniest hint of a weep after a long ride so :thumbsup: from me.
 
Do you guys put a thin layer of silicone inside the fork tube and the outside diameter of the seal during the installation? I pre lube the tube and seal contact area so it's not dry during the installation.

I purchased three pairs of the 500cc single shock front forks thinking the front fork springs and valving would be heavier duty for the bigger engine. Now I need to figure out what kind of oil brand wise and what weight oil. I need an oil weight in between so my son can ride it and I can ride it. I just putt. Probably the stock weight oil might be ok. I'm not sure what the stock weight oil would be?
 
atf seems to work well. comes out pretty clean after some hours as well. it would be a good starting point anyway.
 
ATF is a bout7.5 wt.

I would go with straight 10 wt and see how you go. if its a little fast on the rebound for you Bill, go up to 12.5 by blending a 10 and a 15.

im 80Kg, and 10 wt in the 400 seems pretty good.
