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 The previous version was outdated and no longer supported.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

1988 WR250 revival 2016

in Oz, everything is measured by the blma... a drive to somewhere is a two blma trip, replacing a tyre is a 3 blma job...etc
 
Another small setback, I bought some cases from 2premo, great to deal with, sent some excellent photos, packaged very well, absolutely as described and recommend highly, however my mistake was assuming that '86 250 cases were the same as '87-88 with the exception of the seal flange at the sprocket.
I was wrong. The cavity in the crankcase where the crank wheel fits on the '88 is 115mm across and the crank cheeks are 113.5mm across, the '86 cases are 112.5 across to suit the short stroke crank, I mistakenly assumed that they would be interchangeable.
I'll see if a machine shop can machine the thicker web on the 86 cases to fit the '88 crank. Of course I discovered this after fitting the bearings and crank seal, I hadn't yet assembled the transmission/clutch though!

Tony.

had no idea of that, very sorry
i feel very bad on that
 
I built and assembled a 250 five speed tranny into a 83 250cr bike. The five speed was from a later 80's bike. I can't remember the crank I used. But it worked. Your info is something to think about when swapping parts to make things work.

That's half a mm on a side obstruction. I wonder if it can be machined out using a die grinder with a carbide bit on the case. Or set up the case on a milling machine and bore it out 1/2 mm?
