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 The previous version was outdated and no longer supported.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

125 HVA LEJ 1st liquid cooled

First water cooled cylinder in '77? Prototype? What took Husqvarna so long to change.

Being water cooled allowed for a change in port timing which produced more power but more heat which the water cooling took the heat away.
 
As this LC evolved with different proto types I can see a problem with the water cooled head only. The cylinder and head expanded at different rates. Maybe warpage if the cylinder got hot enough. Then they cooled the cylinder and the head.
These guys were smart. They lead the industry in development.

I stopped by Lars-Erik yesterday, we talked a lot about the water cooled kits he made.
It was only 40 complete kits he produced and delivered to Husqvarna 1983.
Everything else produced was for his own testing.

He still has the very first water cooled cylinder he made back in -77.
It used self circulation without water pump and worked well as long as he was driving fast.
When driving slowly for a longer while would it overheat the water.

I'll bring the camera next time

Bryll,

Do you ever see Lars-Erik ? I rode Roger Harveys 1977 works 125 Husky for a while when he was injured. It had a very special engine that I'd love to know if he worked on it, as a have a lot of questions about it ?

Cheers Steve

I would appreciate that if you could.

The bike was built for Roger Harvey (British 125 GP Rider) for the 1977 GP's. It had a twin reedblock. One in the barrel and one into the crank case. I'd love to know if it was him who developed the engine ? I rode it a couple of times in British Schoolboy championships, when Roger was injured and it was so fast. Here in the UK, my dad who worked for the main Husqvarna Importer (Brian Leask) tried to replicate the set up, but we couldn't get the crank cases to seal properly and the engine kept seizing.

Takk sa mykke.
Steve
 
I'm sorry, but I have been quite busy and forgot to call Lars-Erik.
Will try to remember to give him a call later this week.
Don't think he was involved in that motor, but I will check with him so we know for sure.
