• 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 The previous version was outdated and no longer supported.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 to me 86 WR400

Thanks Dukkman! My cover isn't that bad but the plate is a great idea. Did you seal under the plate too?

Dukkman, please describe the backing plate you made. I'm not clear where it installs on the cover.
The sulfuric acid cleaned out the pits in the metal. I used two Qtips of acid with water rinses. Worked well.
Maybe walnut shell blasting- sandblasting is too aggressive. I would tear a hole in the case.
I think the best chance of success for the JB weld is a clean surface to adhere to.

The real key to using JB Weld in a fluid area is to seal any JB surface that the skin has been sanded or ground off with epoxy or do not remove the skin to start with

Yep , bit of 3 bond just to make sure.
I wish I could take credit for the idea.
I bought my 240 first , the pump was shabby so I came up with the plate idea.
Then I bought my 400 and it already had a plate.
 
So I got it started briefly! Thanks to all you's for your help :cheers:
Unfortunately I sheared the flywheel key because I didn't tighten the flywheel so I'll get another one tomorrow and try again.
 
The bolt was only hand tightened- I'm sure that was the problem.
Is it possible to easily install a decompression lever on a liquid cooled motor?
 
Headstay doesn't work guys .
What it does is hide the problem until it's really bad.
Best cure is to fix the swingarm through the motor bolt/bushes .
Also make sure that the frame holes aren't elongated or you will never stop the vibes.

Yep ajcm those nuts are stepped to use the original studs.
 
Are those decompression valves currently available Dukkman?
Not clear on why a head stay would not work. Without one my old Triumph's shaking is considerably worse.
This assumes all the problems you mentioned have been implemented.

Can't find where I bought those deco's from but they were Harley ones.
Any chainsaw deco will work and there's a guy in NZ who is using Victa Mower ones because they are automatic and don't need resetting.

If you fix the back end/swing arm bolt the vibration goes away and you don't need the headstay anymore.
I made 2 of them .
One for my 400 and as I said after fixing the cause never needed the brace anymore.
The other was on my 240 and I sat down and learn't how to balance the motor which totally removed the vibs AND let the thing rev like a demented 80cc. [ entirely different bike ]
 
Thanks Dukkman! Balancing the engine is a little costly, isn't it? Haven't tackled the Triumph because of the cost. "O
Thanks for the deco info. "It only vibrates a little..."
