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 The previous version was outdated and no longer supported.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

Need 84 250 air cooled cylinder

First I'm not perfect. I'm not always right. I throw out a statement or an idea sometimes looking for an answer or some one else's thoughts. What I perceive isn't always right.
Please forgive me. I'm not here to upset the roost. If I bother anyone here let me know just send me a message.

No other riders including my buddies realize the older husqvarnas are well known for there top speed in desert racing.
 
i agree fran i believe the main limitation of the swede topend in use of the long cylinder studs that even on the 250 really cramp the port design, where the short studs allow much larger transfer and "boost" ports..there was a cool pic floating around here of a "works" lc jug that had the casting around the outside of the long studs, you could actually see the a good part of the studs just hanging out in the port

Don't forget to retorque the base gasket bolts no matter which design you have wether the bike is brand new or a restoration. Run it for a while then reset the torque.

I'm really going to focus more on porting to the husky specs and add them to what I did in the past. My 81 husqvarna cr250 had all my porting done to it. When you wicked it you were in for a wild ride. The 2t engine is very responsive to the throttle.

Advice, When an engine cooks a piston it's not just reboring it and installing a new piston. It's finding the cause why it cooked. I now disassemble the engine, install new crank bearings and seals/gaskets/reeds. Plus boring it for the next over sized piston. Then it's the leak down test.

On our 125cr Honda I found the previous owner removed the cylinder with a screwdriver at the base gasket. I couldn't see the leak but the leak down test found it.

My point is fix it right. Leak down test it. I made a carb manifold solid plug. A block off plate for the exhaust plate with a tire valve installed in the exhaust plate. I used the fork pump to put pressure in the engine. Just 6 to 8lbs. I like it to hold it for 6 to 10 hours.

Just some info to pass on to the new guys. To save you from having problems.
