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 The previous version was outdated and no longer supported.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

Weisco 250 husky piston(air cooled)

.008 clearance on my 84 250WR engine when I got it even though it ran only showed 100 psi on a compression test. I am sure the rings were worn as well. I have since found there was a trend among POs of that bike showing that topends were neglected to the point of having a piston skirt break off and fractured the 250 web in the crankwell. Because of the 430 wall being intact there was never any pressure loss

How noisy was the piston slap?

I'm switching from blendeze castor to maxima 727 castor oil blend. At 20:1 mix. 40:1 super maxima didn't work for me.
 
I only had it running just prior to paying for it at purchase time. The packing in the silencer was shot so I did not hear it. I did not even start after purchase because I wanted to check the engine and mechanical condition. I tested the compression and after finding only 100 psi with wide open throttle I decided to pull the top end. I ended up removing the engine from the frame first because I could not remove the cylinder while it was still in the frame (hitting on the down tube)
 
I learned through experience to freshen every purchase even though it runs good. With my luck in a short time they fail anyway. Most of the time the crank is good. At the cost of crankbearings, seals, new piston, I bore it myself it's well worth it than taking a chance on the crank failing if the piston goes by running it.

Since dirt can get into the open cylinder stud holes I remove the cylinder with the engine case upside down. This way the dirt falls down. But the case gets disassembled and washed anyway. I try to get nothing in the lower bearing n the rod.
