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 The previous version was outdated and no longer supported.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

Squish band clearance

How much squish band clearance is everyone running? I'm thinking about 1.0mm at say sea level is where it should be.

What about head and base gaskets thickness stock? Any options?
How about custom copper gaskets in different thicknesses.

Haha, sorry it did not correlate to my instinks. I only have ac models(except for street), but lots of these fellas have LC bikes. I had an 82 Honda 250r that required .7mm to keep the piston off the gasket I never figured out why til years later(circa 1993). To prevent the failure of their crappy gaskets, but I am sure the newer gaskets are superior. I put an old used copper gasket back into a 1955 Kohler Generator and it has been wonderful, albeit only a year or so with little usage. Check out my vids top see it in operation. One of my proudest builds. Good luck toolie! Chris
 
1.0mm is a good starting point. I have had Cometic make base gaskets in many thicknesses for the AC bikes.
 
Great, thanks.

I'm not sure what current clearance is but I'd like to go in steps just to be on the safe side. The piston was replaced when I bought the bike and being an aftermarket piece it might be off. Just a feeling, compression seems a bit low.
 
It is probably about 1.5mm stock. But ya, go down in steps and see what you feel. Contact Chris Workman at Cometic.
 
So finally got around to checking squish, 1.1-1.2mm which is much tighter than I thought it would be. I'd say someone has adjusted it before. To contrast, my 18 TE300 came in at just under 2mm. The TE is about 1.5 now but I'll be machining 0.3 and try again. I'll be leaving the XC as is.
